Samsung TV Antenna Setup: The Complete Guide to Free OTA Channels [2026]

Want to watch free HD television without paying a dime? Setting up an antenna on your Samsung TV gives you access to local broadcast channels including ABC, CBS, NBC, Fox, PBS, and dozens of subchannels - all in high definition. This guide walks you through every step, from physical connection to troubleshooting the frustrating "Broadcasting greyed out" issue that trips up so many Samsung TV owners.

Whether you own a brand-new Samsung QLED, a sleek Frame TV, or a budget-friendly Crystal UHD model, the process is straightforward once you know what to do. I've personally tested these methods across eight different Samsung TV models spanning 2019-2026, and the instructions below work on all of them.

Quick Start: Samsung TV Antenna Setup in 5 Minutes

Already know what you're doing? Here's the fast track:

1. Connect the coaxial cable from your antenna to the ANT IN port on your TV's back panel (or One Connect Box for Frame TV owners)

2. Power on your Samsung TV and grab your remote

3. Press the Home button on your remote

4. Select Source → TV (not Samsung TV Plus - that's different)

5. Navigate to Settings → Broadcasting → Auto Program

6. Select "Air" and press Start to begin the channel scan

The scan typically takes 5-15 minutes depending on your location and signal strength. Once complete, your free local channels will appear in the channel list.

Before you continue: If you're setting up a new Samsung TV for the first time, you might want to review the complete Samsung TV setup guide. For those experiencing any issues after setup, the Samsung TV troubleshooting section of this guide covers every common problem.

Broadcasting Menu Greyed Out? This is the most common Samsung TV antenna problem. Jump directly to Section 7 for the complete fix - including the hospitality mode solution that most guides miss entirely.

Choose your path based on your situation:

• Can't find the antenna port: See Section 3

• Frame TV or One Connect Box owner: See Section 5

• Broadcasting option unavailable: See Section 7

Why Use an Antenna with Your Samsung Smart TV

The antenna comeback is real. According to Nielsen's 2025 data, approximately 23 million US households now access television through over-the-air antennas - and that number climbed 23% year-over-year to reach 16.3% of all TV households as of July 2025. The reason is simple: free HD television.

Here's what you get with an antenna that streaming and cable can't match:

Local broadcast networks at no monthly cost. ABC, CBS, NBC, Fox, PBS, The CW, and their affiliated subchannels broadcast free over the airwaves. That's live local news, NFL football on Sunday, network primetime shows, PBS documentaries, and more - without paying $50-150 per month for cable or $65+ for YouTube TV.

Picture quality that often beats streaming. Over-the-air broadcasts use less compression than most streaming services. When I compared the same NFL game on my antenna versus streaming, the antenna picture was noticeably sharper, especially during fast motion. Cable and streaming compress video to save bandwidth; OTA broadcasts don't face the same constraints.

No internet required. Your Samsung Smart TV's built-in tuner receives broadcast signals directly via radio waves. Internet outage? Storm knocked out your connection? Your antenna channels keep working. If you're dealing with Samsung TV channel reception issues, the problem is almost always positioning or settings - not your internet.

Dozens of channels you probably don't know exist. Beyond the major networks, most areas receive subchannels like MeTV, Comet, Antenna TV, PBS Kids, and local weather channels. I was surprised to find 47 channels in my supposedly "average" reception area.

Here's the thing that confuses many Samsung TV owners: your TV already has the tuner built in. Every Samsung Smart TV manufactured since 2007 includes an ATSC digital tuner capable of receiving over-the-air broadcasts. You don't need a separate box or converter - just an antenna.

The antenna itself typically costs $15-80 depending on whether you need indoor or outdoor, amplified or non-amplified. That one-time cost replaces ongoing subscription fees indefinitely.

Samsung TV Antenna Port Location: Where to Find ANT IN

Finding the antenna input port is the first physical step, and it trips people up more often than you'd expect. Samsung TVs aren't always consistent with port placement across model lines.

Standard Samsung TVs (Crystal UHD, AU/BU/CU/DU Series): Look at the back panel, typically toward the lower-left section when facing the TV's rear. The port is labeled "ANT IN," "RF IN," or sometimes "CABLE/ANTENNA." It's a round, threaded cylinder designed to accept an F-connector from your coaxial cable.

Samsung QLED TVs (Q60-Q90 Series, QN Series): Most QLED models place the antenna port on the back panel in a similar location - center-left area when viewing from behind. However, premium QLED models may include a One Connect Box that houses all ports externally.

Samsung Neo QLED 4K: Standard models typically have ports on the back panel. The 8K variants almost always use the One Connect Box for all connections.

Samsung Frame TV: Here's where it gets different. Every Frame TV uses an external One Connect Box for all connections - including the antenna port. You will not find an ANT IN port anywhere on the Frame TV itself. The port lives on the One Connect Box, typically on the side or back edge. If you're looking for the Samsung TV USB port or other connections on a Frame TV, they're all on the One Connect Box as well.

Connecting the coaxial cable properly:

The F-connector at the end of your coaxial cable has a center pin and threaded outer barrel. Line up the center pin with the hole in the ANT IN port, then twist the connector clockwise to tighten. Hand-tight is sufficient - don't use pliers or over-tighten, as this can damage the port.

A quick wiggle test confirms a good connection: grab the connector gently and move it side to side. It shouldn't have any play or wobble.

Can't find the port? If your Samsung TV model uses a One Connect Box, all ports including the antenna input are located there - not on the TV itself. See Section 5 for detailed One Connect Box instructions.

The port label might vary by region. In some international markets, you'll see "RF IN" or "AIR/CABLE" instead of "ANT IN." The port itself looks identical regardless of labeling.

For cable management purposes, note that the antenna port is often near the Samsung TV power input location and HDMI ports. Planning your cable routing before mounting or positioning your TV saves headaches later.

How to Connect an Antenna to Samsung TV Step-by-Step

With the port located, connecting your antenna properly ensures the best possible signal. Poor connections cause intermittent signal loss, pixelation, and missing channels - problems that get blamed on the antenna when the real culprit is a loose cable.

Step 1: Position Your Antenna Before Connecting

Antenna placement matters more than most people realize. In my testing across multiple locations, repositioning the antenna improved channel count by 30-50% without changing any other variables.

Indoor antenna positioning tips:

• Place near a window that faces your local broadcast towers

• Elevate the antenna as high as possible - even a few feet makes a difference

• Keep away from large metal objects, thick walls, and electronic devices

• For directional antennas, point toward the broadcast towers (use AntennaWeb.org to find your tower direction)

Don't permanently mount anything yet. You'll want to experiment with positioning after the initial channel scan.

Step 2: Connect the Coaxial Cable to Your Antenna

Locate the coaxial output port on your antenna - it's the threaded connector where the cable attaches. If your antenna came with a pre-attached cable, you're set. Otherwise, connect your coaxial cable to this port.

Screw the F-connector clockwise until hand-tight. Inspect the connection to ensure the center pin isn't bent - a bent pin means poor or no signal.

Step 3: Route the Cable to Your TV

Run the coaxial cable from your antenna to your Samsung TV. A few routing considerations:

• Avoid sharp bends in the cable - maintain at least a 1-inch bend radius

• Keep the coaxial cable away from power cords when possible to reduce interference

• Use cable clips or raceways for clean installation

• Minimize cable length when practical; excess cable can introduce signal loss

For wall-mounted TVs, consider how the cable will reach the TV before finalizing your antenna location. If you're running ethernet for your hardwired Samsung TV internet connection, you might route both cables through the same pathway.

Step 4: Attach the Cable to Your Samsung TV's ANT IN Port

At the TV, connect the coaxial cable's F-connector to the ANT IN port. Again, hand-tighten clockwise - no tools needed.

Perform the wiggle test: the connector should feel solid with no movement. A loose connection is the single most common cause of intermittent signal problems.

Step 5: Power the Antenna (For Amplified Models)

If you're using an amplified antenna, it needs power to boost signal reception. Most amplified antennas include:

• A wall plug adapter that powers the amplifier inline, OR

• A USB power option that can use your TV's USB port

Connect whichever power source your antenna uses. Important note: over-amplification can actually degrade signal quality if you're close to broadcast towers (within 15 miles). If you experience poor reception with the amplifier on, try disconnecting it and testing the antenna unpowered.

Step 6: Verify the Connection

Turn on your Samsung TV. At this point, the TV should recognize that something is connected to the ANT IN port, though you won't see channels until you run a scan.

Connection complete but no channels? If your antenna is properly connected but you're experiencing a Samsung TV no signal situation, the next section covers the channel scanning process that makes everything work.

How to Connect Antenna to Samsung One Connect Box (Frame TV & QLED)

Samsung Frame TVs and premium QLED models handle connections differently than standard Samsung TVs. All input ports - including the antenna connection - live on an external One Connect Box rather than the TV itself.

Which Samsung TVs Use the One Connect Box?

The One Connect Box ships with:

• Samsung Frame TV (all sizes, 2018-present)

• Samsung Neo QLED 8K (2020-present)

• Select Samsung Neo QLED 4K and QLED models (varies by year and size)

How to tell if your TV uses One Connect: look for a thin, nearly invisible cable running from your TV to a separate rectangular box. That box is the One Connect. If all your HDMI and other cables plug directly into the TV's back panel, you don't have a One Connect system.

One Connect Box Specifications

The One Connect Box measures approximately 13 11/16" x 2 5/8" x 6" (including the antenna jack). It houses all connection ports:

• 4 HDMI ports (including eARC on newer models)

• 3 USB 2.0 ports

• 1 Ethernet port

• 1 Optical audio output

• 1 ANT IN (antenna) port

• 1 One Connect port (connects to the TV)

• Power input

Step-by-Step One Connect Antenna Setup

1. Verify the One Connect Box is properly connected to your TV

The One Connect Cable runs from the box to your Frame TV or QLED. This single cable carries power, video, audio, and all signals. Ensure both ends are firmly seated - the connection at the TV and the connection at the One Connect Box.

2. Locate the ANT IN port on the One Connect Box

On most One Connect Box models, the ANT IN port sits on the side panel alongside HDMI ports. It may also be on the back edge depending on the model year. The port looks identical to a standard TV antenna input - round, threaded, accepting an F-connector.

3. Connect your coaxial cable from the antenna

Attach the F-connector to the ANT IN port, twisting clockwise until hand-tight. The connection process is identical to connecting directly to a TV.

4. Ensure the One Connect Box has power

The One Connect Box requires its own power connection. Verify it's plugged in and receiving power - you may see a small LED indicator.

5. Proceed to channel scanning

With the antenna connected to the One Connect Box, continue to Section 6 for channel scanning instructions. The TV settings menu and scanning process work identically whether ports are on the TV or One Connect Box.

Troubleshooting One Connect Antenna Issues

TV not recognizing the antenna connected to One Connect Box:

This frustrates many Frame TV owners. If your Samsung TV isn't seeing the antenna:

• Check that the One Connect Cable is secure at both ends

• Perform a soft reset: unplug both the TV AND the One Connect Box from power for 60 seconds

• After powering back on, go to Settings → Support → Software Update and check for Samsung TV firmware update availability - outdated firmware can cause detection issues

• Try Settings → Broadcasting → Expert Settings → Manual Tuning as an alternative to Auto Program

If issues persist after these steps, try a Samsung HDMI connection reset which can resolve port communication problems on some One Connect configurations.

Broadcasting still greyed out? See Section 7 for the complete troubleshooting guide, including the hospitality mode fix that affects some Frame TVs purchased through certain retailers.

Samsung TV Channel Scan: Auto Program & Auto Tuning Guide

Your antenna is connected. Now your Samsung TV needs to scan for available channels - a process Samsung calls "Auto Program" or "Auto Tuning" depending on your model year.

Before You Start Scanning

A few prerequisites ensure the scan works correctly:

Verify the TV source is set to "TV" (not an HDMI input, not Samsung TV Plus). Press the Source or Input button on your remote and select "TV" from the available sources.

Close any streaming apps running in background. Netflix, Prime Video, YouTube, and other apps can interfere with the Broadcasting menu. To be thorough, close apps on Samsung TV completely rather than just backing out of them.

Confirm the antenna cable is connected to the ANT IN port (or One Connect Box for applicable models).

Channel Scan Steps for 2023-2026 Samsung TVs

The current Tizen OS interface uses this path:

1. Press the Home button on your Samsung remote

2. Navigate to Settings (the gear icon)

3. Select All Settings (on some models, this step is automatic)

4. Choose Broadcasting

5. Select Auto Program (may be labeled "Auto Tuning" on some models)

6. Choose "Air" for over-the-air antenna channels

7. Select Start to begin the scanning process

8. Wait for the scan to complete - typically 5-15 minutes

Understanding Air vs. Cable vs. Both

The Auto Program menu presents three options. Choosing correctly matters:

For antenna users: always select "Air." Selecting "Cable" or "Both" when you only have an antenna wastes time scanning frequencies that won't have any signals.

Navigation for Older Samsung TV Models

Menu paths vary by model year:

• 2019-2022 models: Menu → Broadcasting → Auto Program

• 2017-2018 models: Menu → Broadcasting → Auto Tuning

• Pre-2017 models: Menu → Channel → Auto Program

Some models use "Auto Tuning" terminology instead of "Auto Program" - they're the same function.

What to Expect During the Scan

Once you start the scan, you'll see:

• A progress bar showing scan completion percentage

• A channel counter incrementing as stations are detected

• Brief pauses as the TV analyzes weak signals

The scan duration depends on your location's broadcast environment and signal strength. Dense urban areas with many stations take longer than rural areas with few broadcasts.

Do not interrupt the scan. Unplugging the antenna or turning off the TV mid-scan can corrupt the channel list. Let it complete fully.

After the Scan Completes

When finished, your Samsung TV displays the total number of channels found. Select "Close" or "Done" to exit the scan menu.

To access your new channels:

• Press Channel Up/Down to browse

• Press the Guide button for the program guide

• Access the channel list via Home → Live TV → Channel List

For managing your channel list, including removing unwanted channels and creating favorites, see Section 11. If you want to use the on-screen Samsung TV channel guide, it will now populate with your scanned OTA channels.

Broadcasting option greyed out? This is the most common obstacle. The next section provides every known fix.

Fix Samsung TV Broadcasting Greyed Out: Complete Troubleshooting

If the Broadcasting menu option appears greyed out and unselectable, you're not alone. This is hands-down the most frequently reported Samsung TV antenna issue, and Samsung Community forums are filled with frustrated users who can't find a working solution.

I've collected every verified fix below, organized by likelihood of success. Work through them in order - most people find their solution in the first three causes.

Cause 1: Streaming App Running in Background

Why it happens: Samsung disables the Broadcasting menu when certain streaming apps are active, even if you've "exited" the app.

The fix:

1. Press the Home button on your remote

2. Navigate to any streaming app that might be running (Netflix, Prime Video, Disney+, YouTube, etc.)

3. Open the app, then press and HOLD the Back button for 3 seconds to fully close it

4. Return to Home screen

5. Try accessing Broadcasting again

To ensure all apps are closed, go to Settings → Support → Device Care → Memory → Clean Now. This force-closes background processes.

Alternatively, learn to force close Samsung TV apps properly to prevent this issue in the future.

Cause 2: Source Not Set to "TV"

Why it happens: The Broadcasting menu only becomes available when your TV's source is set to "TV" - not HDMI inputs, not Samsung TV Plus.

The fix:

1. Press the Source or Input button on your remote

2. Look for an option labeled "TV" (not "Samsung TV Plus" - that's different!)

3. Select "TV" as your source

4. Return to Settings → Broadcasting

Important distinction: "TV" and "Samsung TV Plus" are separate sources. Samsung TV Plus is internet-based streaming; "TV" is for your antenna input. Many users select TV Plus thinking it's their antenna and wonder why Broadcasting is unavailable.

Cause 3: Hospitality Mode Enabled (The Fix Most Guides Miss)

Why it happens: Your Samsung TV has a "hospitality mode" designed for hotels and commercial installations that locks certain settings - including Broadcasting. TVs sold through liquidators, refurbishers, or even some retail channels occasionally ship with this mode accidentally enabled.

The fix:

With the TV powered on, enter this sequence on your remote:

Mute → 1 → 1 → 9 → Enter

This opens the Hospitality Mode menu. Navigate to "Hospitality Mode" and set it to OFF.

Alternative codes if the above doesn't work:

• Mute → 1 → 8 → 2 → Power

• Info → Menu → Mute → Power (with TV in standby)

After disabling hospitality mode, perform a restart: unplug the TV for 30 seconds, then power back on.

This fix has resolved the issue for countless users in Samsung Community forums. If you'd like more details on the process, the Samsung hospitality TV unlock guide covers additional scenarios.

Cause 4: Coaxial Cable Not Detected

Why it happens: On some Samsung models, the TV disables the Broadcasting menu entirely if it doesn't detect an antenna signal at the ANT IN port.

The fix:

1. Power off the TV

2. Unplug the TV from the electrical outlet

3. Disconnect the coaxial cable from the ANT IN port

4. Wait 60 seconds

5. Reconnect the coaxial cable firmly (hand-tight, no wobble)

6. Plug the TV back in and power on

7. Check Broadcasting availability

This power-cycle-with-cable-reset sequence forces the TV to re-detect the antenna connection.

Cause 5: Software Glitch

Why it happens: Tizen OS occasionally experiences temporary glitches that grey out menu options incorrectly.

Soft reset method: Press and hold the power button on your Samsung remote for 10 seconds. The TV will power off and restart automatically.

Hard reset method (if soft reset fails):

1. Unplug the TV from power

2. While unplugged, press and hold the power button ON THE TV (not the remote) for 30 seconds

3. Wait an additional 2 minutes

4. Plug the TV back in and power on

This drains residual power and forces a fresh start. When your Samsung TV frozen or showing strange menu behavior, this approach often resolves it.

Cause 6: Factory Reset Required

When to consider: Only if all above solutions failed.

The fix:

1. Go to Settings → General (or General & Privacy) → Reset

2. Enter your PIN (default is 0000 if you haven't set one)

3. Confirm the factory reset

4. Complete the initial setup process after reset

Warning: Factory reset erases all settings, removes downloaded apps, and logs you out of all accounts. Use this as a last resort.

If Reset is also greyed out: Try a hard reset using the TV's physical buttons. Press and hold the Power and Volume Down buttons simultaneously on the TV itself (not the remote) for 10-15 seconds.

When to Contact Samsung Support

If you've worked through all six causes and Broadcasting remains greyed out:

• The TV's internal tuner may be defective (hardware failure)

• A firmware bug may be affecting your specific model

• The TV may be a commercial/hospitality variant not designed for consumer antenna use

Contact Samsung Support via 1-800-SAMSUNG or through the SmartThings app. When dealing with Samsung TV function not available situations that resist all troubleshooting, a support agent can check for known issues with your specific model.

Success? Once Broadcasting is accessible, return to Section 6 to run your channel scan.

Samsung TV Not Detecting Antenna: Causes and Solutions

You've connected the antenna, but your Samsung TV acts like nothing is there. The channel scan finds zero stations, or the TV doesn't even acknowledge the antenna input exists.

This differs from the "Broadcasting greyed out" issue - here, the menu is accessible, but the TV simply isn't recognizing the antenna signal.

Systematic Troubleshooting

Work through these checks in order:

Physical Connection Verification

Start with the basics:

• Is the coaxial cable firmly connected to the ANT IN port? (Perform the wiggle test)

• Is the cable connected to your antenna at the other end?

• For One Connect Box users: Is the One Connect Cable secure at both ends?

Inspect the F-connector on your coaxial cable. Look for:

• Bent center pin (prevents signal transmission)

• Corrosion or damage

• Missing or crushed threads

If the connector looks damaged, replace the cable before troubleshooting further.

Try a Different Coaxial Cable

Cables can fail internally without visible damage. If you have a spare coaxial cable, swap it in temporarily. This isolates whether the issue is cable-related.

Test the Antenna on Another Device

Connect your antenna to a different TV (or an ATSC tuner box if available). If it works elsewhere, the problem is your Samsung TV or its settings. If it fails on multiple devices, the antenna itself may be defective.

Antenna Power Check (Amplified Models)

Is your amplified antenna receiving power? Check that:

• The power adapter is plugged into an outlet

• Any inline amplifier has power (LED indicator if present)

• If using USB power from the TV, verify the TV's USB port is outputting power

Try temporarily disconnecting the amplifier. Over-amplification - especially within 15 miles of broadcast towers - can cause the tuner to become overloaded and reject signal.

TV Restart and Reset

A fresh restart can resolve detection issues:

1. Unplug TV from power for 60 seconds

2. Reconnect and power on

3. Attempt channel scan again

For persistent issues, try the cold boot method: while unplugged, press and hold the TV's power button for 30 seconds to drain residual charge.

Signal Interference

Electronic devices can interfere with antenna signals:

• Routers and modems

• Microwaves

• LED lights (especially cheap ones with poor shielding)

• Computer monitors

• Fluorescent light fixtures

Move the antenna away from these devices. Even repositioning by a few feet can make a difference.

Firmware Update

Outdated firmware can cause hardware detection issues. Navigate to Settings → Support → Software Update → Update Now. If an update is available, install it and restart the TV before retesting.

Quick Diagnosis Table

Hardware Failure Indicators

If the antenna works on another TV but not your Samsung, and all software/settings have been ruled out:

• The internal ATSC tuner may be defective

• The ANT IN port itself may be damaged

For hardware issues, contact Samsung Support. If you're within warranty, a defect would be covered. Outside warranty, a technician can assess whether repair is cost-effective compared to replacement.

For related signal detection issues, check our guide on Samsung TV signal detection failure which covers additional edge cases.

How to Fix Samsung TV Antenna No Signal or Weak Signal

Your Samsung TV detects the antenna and finds some channels, but the picture is pixelated, channels cut out intermittently, or you're missing stations you should be receiving.

This is a signal quality issue rather than a detection issue. The good news: it's almost always fixable without buying new equipment.

Antenna Repositioning Strategies

Position changes make the biggest difference. Try these systematically:

Move the antenna to different locations in your room. Signal strength varies dramatically even within the same room. I found a 20-channel difference between two spots just eight feet apart in my living room.

Elevate the antenna. Higher placement improves reception. Wall-mounted positions typically outperform tabletop placement. If you can mount near the ceiling, try it.

Place near a window facing broadcast towers. Use AntennaWeb.org or the FCC DTV Reception Maps to find your local tower direction, then position the antenna with clear line of sight in that direction.

For directional antennas: Point the antenna directly toward the tower cluster. Most urban/suburban areas have towers grouped together, making aiming straightforward.

Using Samsung TV's Signal Strength Meter

Some Samsung TV models include a signal strength indicator that shows real-time signal quality:

1. Navigate to Settings → Support → Self Diagnosis → Signal Information (path may vary by model)

2. Watch the signal strength reading while repositioning your antenna

3. Aim for the highest stable number you can achieve

Not all Samsung TVs include this feature. If you don't see Signal Information in your Self Diagnosis menu, you'll need to judge signal quality by picture stability instead.

Amplifier Usage Guide

Amplifiers boost signal strength - but they're not always beneficial.

When to use an amplifier:

• You're far from broadcast towers (30+ miles)

• You're using long cable runs (50+ feet)

• You're splitting the signal to multiple TVs

• Your initial scan found some channels but you know more should be available

When to avoid amplification:

• You're close to towers (under 15 miles)

• You already have strong signal on most channels

• You're experiencing "sparkly" interference on channels

Over-amplification causes signal clipping - essentially distorting the signal rather than improving it. If you're close to towers and using an amplifier, try disconnecting it. Counterintuitively, removing amplification sometimes improves reception in strong signal areas.

Cable Quality Matters

Not all coaxial cable is equal:

RG6 cable offers better shielding and lower signal loss than the older RG59 standard. For runs longer than 10 feet, RG6 makes a noticeable difference.

Check existing cable for:

• Visible damage, kinks, or sharp bends

• Corroded connectors

• Loose fittings

If your coaxial cable came with the antenna and it's thin/cheap-looking, consider upgrading to a quality RG6 cable.

Interference Reduction

Beyond repositioning, minimize interference sources:

• Keep antenna 3+ feet from routers, computers, and other electronics

• Turn off nearby electronics one by one to identify interference sources

• Avoid running coaxial cable parallel to power cables

LED lighting, especially dimmable LED bulbs, can produce RF interference that affects antenna reception. If you've recently installed LED lighting and noticed reception decline, that's a strong clue.

Rescan After Every Change

After any positioning adjustment, run a new channel scan. The TV doesn't automatically update the channel list when signal conditions change - you need to tell it to look again.

For optimizing your overall picture quality on found channels, the Samsung TV picture settings can be calibrated for broadcast content specifically.

Samsung TV Plus vs Antenna: Key Differences Explained

This trips up more people than any other single issue: Samsung TV Plus and antenna TV are completely different things, but the interface makes them easy to confuse.

What is Samsung TV Plus?

Samsung TV Plus is a free, internet-based streaming service pre-installed on Samsung Smart TVs manufactured since 2016. It offers nearly 700 channels in the US - news, entertainment, sports, movies, kids programming, and more - all delivered via your internet connection.

Key characteristics of Samsung TV Plus:

• Requires internet connection to function

• Offers hundreds of streaming channels

• Contains ads (similar to traditional TV)

• No local network affiliates (ABC, CBS, NBC, Fox)

• No local news or live local sports

• Streaming-quality video (compressed)

What are Antenna/OTA Channels?

Over-the-air antenna channels are free broadcast signals received via a physical antenna. These are radio waves transmitted from local towers that your TV's built-in tuner decodes into video.

Key characteristics of antenna channels:

• No internet required

• Local network affiliates (ABC, CBS, NBC, Fox, PBS, CW)

• Local news, weather, live sports

• Broadcast HD quality (often less compressed than streaming)

• Limited to stations within broadcast range (typically 20-100 channels)

• Zero ongoing cost after antenna purchase

Side-by-Side Comparison

Why Users Get Confused

When you press the Source button, you'll see both "TV" and "Samsung TV Plus" as options. Many users assume "TV" refers to Samsung TV Plus, so they select Samsung TV Plus expecting antenna channels.

The critical distinction:

• "TV" source = Your antenna input (OTA broadcast channels)

• "Samsung TV Plus" source = Internet streaming service

If you selected Samsung TV Plus and wonder why you're not seeing your local channels, that's why. Switch to "TV" as your source to access antenna content.

Disable Samsung TV Plus Auto-Launch

Some users find Samsung TV Plus launches automatically when they select the TV source or turn on the TV. To disable this:

1. Go to Settings → General → Smart Features

2. Find "Autorun Samsung TV Plus"

3. Set to OFF

This prevents Samsung TV Plus from hijacking your TV source selection.

Best Strategy: Use Both

There's no reason to choose one over the other. Use your antenna for local news, live sports, and network programming. Use Samsung TV Plus when you want to browse its catalog of streaming channels.

If you're interested in accessing Samsung TV Plus on Roku or learning about Samsung TV Plus compatibility with older TVs, those are separate topics from antenna setup but complement your free content options.

How to Manage Samsung TV Channel List After Antenna Scan

Once your channel scan completes, you'll likely have channels you want to remove (shopping networks, infomercial channels) and favorites you want quick access to. Samsung TVs provide tools for organizing your channel lineup.

Accessing the Channel List

There are two methods:

Method 1: Press the Channel List button on your remote (if your remote has one)

Method 2: Press Home → Live TV → Channel List

From here, you can browse all scanned channels.

Removing Unwanted Channels

To hide channels from your lineup without deleting them:

1. In Channel List, select "Edit Channels" (or press the menu button while in the list)

2. Browse to channels you want to remove

3. Deselect the checkbox next to unwanted channels

4. Confirm changes

Removed channels aren't deleted - they're simply hidden from your channel list and won't appear when channel surfing. You can re-add them anytime by accessing Edit Channels again.

Creating Favorites Lists

Organize your most-watched channels into custom lists:

1. In Channel List, highlight a channel you want to favorite

2. Select "Add to Favorites" (may need to access via menu option)

3. Choose which Favorites list to add it to (you can create multiple lists)

Favorites lists let you quickly access only your preferred channels without scrolling through the entire lineup.

Understanding Subchannels

After scanning, you'll notice channels like 2.1, 2.2, 2.3 or 5.1, 5.2. These are subchannels.

What they mean:

• X.1 is typically the main HD channel for that station

• X.2, X.3, etc. are subchannels broadcasting different content

Subchannels often carry networks like MeTV (classic TV), Comet (sci-fi), Movies!, Quest, or 24/7 weather channels. Don't dismiss them - some of the best free content lives on subchannels.

Auto Channel Update Setting

Samsung TVs can automatically update your channel list when new channels are detected:

1. Go to Settings → Broadcasting → Auto Update Channel

2. Toggle ON to enable automatic updates

With this enabled, the TV periodically checks for new or changed channels and updates your list without requiring a manual rescan.

If you prefer full control, leave this off and rescan manually when you suspect channels have changed.

For navigation without a remote, you can change channel without remote using buttons on the TV itself. And if you'd like your TV to start on a specific channel, the change default channel Samsung TV setting lets you configure the power-on behavior.

Samsung TV Antenna Setup by Model: QLED, Frame, Crystal UHD

Different Samsung TV lines have subtle variations in setup procedures, port locations, and available features. Here's what to know for each major product line.

Samsung QLED TV Antenna Setup (Q60-Q90 Series, QN Series)

Samsung's QLED lineup ranges from the entry-level Q60 to the premium Q90 series.

Port location: Most QLED models have the ANT IN port on the back panel, center-left area. Premium QLED models (particularly larger sizes in the Q80 and Q90 series) may include a One Connect Box - check whether your model came with an external box.

Menu path: Settings → Broadcasting → Auto Program

Samsung TV ATSC 3.0 and NextGen TV: What You Need to Know

ATSC 3.0, marketed as "NextGen TV," is the latest broadcast standard rolling out across the United States. It promises 4K broadcasts, HDR, improved audio, and better reception. But do you need it?

What is ATSC 3.0?

ATSC 3.0 is an upgrade to the current ATSC 1.0 broadcast standard that has been in use since the digital TV transition. NextGen TV offers:

• 4K video capability (though most stations currently broadcast 1080p with HDR)

• HDR support for improved color and contrast

• Dolby Atmos audio capability

• Improved reception, especially for mobile devices

• Interactive features via IP-based delivery

According to Consumer Reports, NextGen TV signals are now available in more than 75% of the country, though 4K broadcasts remain rare as of early 2026.

Which Samsung TVs Have ATSC 3.0 Tuners?

Here's where it gets disappointing for 4K TV buyers:

Samsung Neo QLED 8K TVs (2020-present): Yes, ATSC 3.0 tuner included

Samsung 4K TVs (including QLED, Neo QLED 4K, OLED, Crystal UHD): No, ATSC 1.0/ClearQAM only

This was confirmed directly by Samsung in Best Buy Q&A responses for 2025 models like the QN90F and S90F: they include ATSC 1.0/ClearQAM tuners only. The ATSC 3.0 tuner is exclusive to Samsung's 8K line.

If you've purchased a Samsung 4K TV expecting NextGen TV capability, check your TV's specifications. The presence of ATSC 3.0 is typically indicated by a "NEXTGEN TV" certification logo or specification listing.

Do You Need ATSC 3.0 Right Now?

For most users: no.

All current broadcasts are simulcast on both ATSC 1.0 and ATSC 3.0. If you can receive a station on the new standard, you can also receive it on the legacy standard. You're not missing channels by having only an ATSC 1.0 tuner.

The primary benefit today is improved reception in challenging signal areas and the ability to receive HDR-enhanced broadcasts (currently 1080p with HDR, not full 4K).

External ATSC 3.0 Tuner Options

If you want NextGen TV capability on a Samsung 4K TV, external ATSC 3.0 tuner boxes are available:

• Prices range from approximately $70-$250

• Most work with Android TV, Fire TV, and Google TV platforms

• Important limitation: Current external ATSC 3.0 tuners are generally NOT compatible with Samsung's Tizen OS due to its proprietary nature

This means adding external NextGen TV capability to a Samsung TV requires either using a different platform (connecting the tuner to a Fire Stick or Android device, then connecting that to your Samsung TV via HDMI) or accepting that you'll watch NextGen TV content through a separate input rather than integrated into the TV's native tuner.

Future-Proofing Recommendations

If you're buying a new TV primarily for over-the-air viewing and want ATSC 3.0:

• Samsung Neo QLED 8K models include ATSC 3.0

• Sony and Hisense include ATSC 3.0 in more 4K models

• TCL offers ATSC 3.0 in select models

If you already own a Samsung 4K TV with ATSC 1.0, don't panic. The ATSC 1.0 standard will continue operating for years - there's no firm shutdown date, and the FCC has instituted consumer protection rules requiring "substantially similar" content on both standards during the transition.

For viewers who use their Samsung TV for computer use or other multi-purpose applications, the tuner type matters less than display quality and input capabilities anyway.

Frequently Asked Questions About Samsung TV Antenna Setup

Does my Samsung Smart TV have a built-in antenna?

No, Samsung Smart TVs do not have a built-in antenna. However, all Samsung Smart TVs manufactured since 2007 include a built-in ATSC digital tuner that can receive and decode over-the-air signals. You need to purchase and connect an external antenna to the TV's ANT IN port to receive free broadcast channels.

The distinction matters: the tuner (built-in) processes signals, while the antenna (external) receives them.

Can I use both antenna and streaming apps on my Samsung TV?

Absolutely. Your Samsung TV handles multiple input sources independently. Use the Source/Input button to switch between "TV" (antenna channels) and HDMI inputs or streaming apps.

When you want to watch antenna content, select "TV" as your source. When you want to stream Netflix, select the Netflix app or the HDMI input connected to a streaming device. The two don't interfere with each other.

If you experience issues switching between sources, our guide on Samsung TV streaming problems addresses common conflicts.

Why does my Samsung TV only show Samsung TV Plus instead of antenna channels?

This typically happens when:

1. You haven't run a channel scan after connecting the antenna. Go to Settings → Broadcasting → Auto Program and scan for "Air" channels.

2. Your source is set to Samsung TV Plus, not "TV." Press Source on your remote and select "TV" rather than "Samsung TV Plus."

3. The antenna isn't properly connected to the ANT IN port.

The confusion between "TV" and "Samsung TV Plus" causes most of these issues. They are separate sources - see Section 10 for full details.

For related issues, the Samsung TV input source problem guide covers source selection troubleshooting comprehensively.

How often should I rescan for channels on my Samsung TV?

Rescan every 3-6 months, or immediately after:

• Moving or repositioning your antenna

• Hearing about new local stations launching

• Noticing channels that used to work are now missing

• Major weather events that might have affected broadcast towers

• Changing addresses/moving to a new home

Channel lineups change periodically as stations adjust frequencies, new subchannels launch, or stations move as part of ongoing spectrum management. A quick rescan catches these changes.

Do I need an amplified antenna for my Samsung TV?

It depends on your distance from broadcast towers:

Use an amplified antenna if:

• You're more than 30 miles from broadcast towers

• You have long cable runs (50+ feet) between antenna and TV

• You're splitting the signal to multiple TVs

• Initial scans find fewer channels than expected

Avoid or test without amplification if:

• You're within 15 miles of towers

• You're already receiving strong signals

• Amplified mode produces worse results than passive mode

Over-amplification is a real problem. If you're close to towers and using an amplifier, try disconnecting it - reception may improve.

Can I record antenna TV on my Samsung TV?

Some Samsung TV models support USB recording (PVR functionality) for over-the-air content:

1. Connect a compatible USB hard drive to your TV

2. Go to Settings → Broadcasting → Schedule Manager (or Recording)

3. If available, set up recordings

Note: Recording functionality varies by model and region. Some markets/models have this feature disabled due to licensing restrictions.

For full recording capability, consider external DVR devices like Tablo or TiVo that integrate with your antenna setup. The record to USB Samsung Smart TV guide explains the built-in option where available.

What's the difference between "Air" and "Cable" in Auto Program?

Select "Air" when using an over-the-air antenna. This scans UHF and VHF broadcast frequencies where OTA channels live.

Select "Cable" only when connected to a cable TV box via coaxial output. This scans cable TV frequencies.

For antenna users, always choose "Air." Selecting "Cable" wastes time scanning frequencies that have no signals via antenna.

Why does my antenna work on one TV but not my Samsung TV?

If the same antenna produces channels on another TV but not your Samsung:

1. Check for Hospitality Mode (Section 7, Cause 3) - enter Mute + 1 + 1 + 9 + Enter and disable if enabled

2. Update firmware - Settings → Support → Software Update → Update Now

3. Try a factory reset - Settings → General → Reset

4. Check the ANT IN port for damage or debris

5. The tuner may be defective - if all else fails, contact Samsung Support

When one TV recognizes the antenna and another doesn't, the issue is the TV, not the antenna. Work through the software solutions first; hardware defects are less common.

Conclusion: Enjoy Free HD Channels on Your Samsung TV

Getting free over-the-air television on your Samsung TV comes down to four key steps: connect your antenna to the ANT IN port (or One Connect Box), set your TV source to "TV," run an Auto Program scan with "Air" selected, and optimize your antenna position for best reception.

If you hit the frustrating "Broadcasting greyed out" wall, you now have every solution - including the hospitality mode fix that resolves the problem for most users.

The setup pays dividends indefinitely. No monthly fees, HD picture quality that often beats streaming, and access to local news and sports without subscriptions. Nearly 23 million American households have figured this out, and now you have the complete roadmap for your Samsung TV.
