How to Connect an Antenna to Your LG TV: Complete Setup Guide (2026)

Introduction: Why Connect an Antenna to Your LG TV in 2026

Free over-the-air television isn't some relic from your parents' living room. According to Nielsen's research, nearly 23 million U.S. households access TV programming through a digital antenna - and that number keeps climbing. As of November 2025, broadcast-only OTA households had grown 26% year-over-year according to TVB research data, reaching 18.1% of all TV homes.

The appeal is straightforward: dozens of local channels in full HD, completely free, with no monthly bill. Your local ABC, CBS, FOX, NBC, and PBS stations broadcast over the airwaves at no charge. All you need is an antenna and an LG TV with a built-in tuner.

This guide walks you through the entire LG smart TV antenna setup process - from unboxing your equipment to watching your first channel. We cover physical connection, software configuration across all webOS versions (3.0 through 24), channel scanning, signal optimization, and troubleshooting the most common issues. Whether you own a 2014 LG model or a brand-new 2026 set, you'll find version-specific instructions here.

The whole process typically takes 10–20 minutes for most people. If you've connected an HDMI cable before, you can handle this.

For those who haven't purchased an antenna yet or want to explore antenna-free options, we also cover how to get local channels on LG TV without antenna later in this guide. And if you're still evaluating whether LG was the right choice, we think you'll find it handles OTA content beautifully - more on why is LG a good TV brand in our dedicated review.

What You Need Before Connecting an Antenna to Your LG TV

Skipping the preparation step is the fastest way to waste an afternoon troubleshooting problems that never needed to happen. Before you touch a single cable, gather these items and confirm your TV is compatible.

Equipment Checklist

1. A digital OTA antenna (indoor or outdoor) - any standard TV antenna works with LG TVs

2. A coaxial cable with F-type connectors - use RG-6 cable, not the older RG-59 standard. RG-6 has better shielding and handles digital signals with less interference

3. Your LG TV remote control - you'll need it for the channel scanning process

4. Access to your LG TV's ANT IN or RF IN port on the back panel

5. A USB port or wall outlet - only if you're using an amplified antenna that requires power

If you're unsure what type of antenna for LG TV works best for your location, we cover that in detail in Section 11. For now, know that any antenna with a standard coaxial output will work.

Verify Your LG TV Has an Antenna Port

Most LG TVs from 2014 through 2026 include an ANT IN port on the back panel. It's a round, threaded F-type connector rated at 75 Ohms - the same connector used for cable TV.

However, some 2024 and newer budget LG models have removed the coaxial port entirely. The LG 50UT7570PUB, for example, ships without a coaxial connector according to Best Buy Q&A confirmations. If your TV lacks this port, you'll need an external ATSC digital tuner box connected via HDMI - we'll cover that workaround shortly.

To check whether your specific model has the port, how to find LG TV model number explains how to locate your model info, which you can then cross-reference on LG's product support pages.

Understanding Connector Types

In North America, LG TVs use the F-type coaxial connector. If you purchased your LG TV in the UK, Europe, or parts of Asia, it may use the IEC 169-2 (Belling Lee) connector instead - a push-on style rather than threaded. Make sure your coaxial cable matches your TV's connector before purchasing.

The antenna port is distinct from HDMI, USB, or optical ports. If you're having trouble identifying the various connections on your TV's back panel, our guide on where are HDMI ports on LG TV can help you distinguish between them. You can also check does LG TV have Bluetooth for a broader look at your TV's connectivity options.

Check Your Local Channel Availability First

Before you invest in an antenna, verify what channels are available in your area. Two free tools make this easy:

• AntennaWeb.org (sponsored by the National Association of Broadcasters) - enter your address to see available channels, tower distances, and recommended antenna types

• FCC DTV Reception Maps - the FCC's official signal prediction tool showing which stations you can expect to receive

Both tools take about 30 seconds and will save you from buying an antenna only to discover your area has limited coverage.

How to Find the Antenna Input Port on Your LG TV

The antenna input on an LG TV is located on the back panel, typically grouped with the HDMI and USB ports. It's labeled "ANT IN," "RF IN," or "Antenna/Cable In" and accepts a standard coaxial cable with an F-type connector. Some newer budget LG models may not include this port.

Finding the right port sounds simple, but forum posts reveal that port misidentification causes real headaches - especially on models that have both an antenna port and a satellite port.

Port Identification Tips

• Look for the threaded coaxial connector - it's distinctly different from the flat HDMI ports or rectangular USB ports

• The label typically reads "ANT IN" on North American models or "RF IN" on some international variants

• On most LG TVs, it sits in the lower-right cluster of ports when viewed from behind

• Don't confuse it with HDMI inputs - if you need help distinguishing them, how to change HDMI on LG TV covers port identification in detail

Satellite IN vs. Antenna IN - Critical Distinction

Some LG models (particularly those sold in markets with integrated satellite options) feature both a Satellite IN port and an Antenna/Cable IN port. These look similar but serve different purposes.

Connecting your OTA antenna to the Satellite IN port won't work. The satellite tuner expects a completely different signal. Always use the port labeled ANT IN or Antenna/Cable In for your OTA antenna.

What if Your LG TV Doesn't Have a Coaxial Port?

If you've checked the back panel and there's genuinely no coaxial input, your LG TV likely belongs to one of the newer budget lines that removed this port. The workaround is straightforward: purchase an external ATSC digital tuner box (typically $25–$50), connect your antenna to the tuner box, then connect the tuner box to your TV via an HDMI port.

If the antenna option appears grayed out in your TV's settings menu, that's a different issue - usually caused by hotel mode or a firmware glitch. We cover the fix in Section 10 (Troubleshooting). For other display-related issues you might encounter alongside antenna problems, how to fix LG TV screen problems is worth checking.

To confirm your specific model's port availability, how to find LG TV model number will guide you through locating the model information you need.

How to Physically Connect an Antenna to Your LG TV Step-by-Step

To connect an antenna to your LG TV: position the antenna near a window at an elevated location, run a coaxial cable from the antenna to the TV, connect the cable to the ANT IN port, power on any amplified antenna accessories, turn on the TV, and run a channel scan.

Here's each step in detail.

Step 1: Position Your Antenna

Place the antenna near a window, ideally facing the direction of your local broadcast towers (use AntennaWeb.org to determine tower direction). Elevation matters - a shelf or window mount works better than floor level. Keep the antenna away from large metal objects, thick concrete walls, and electronic devices like WiFi routers that generate interference.

Step 2: Route the Coaxial Cable

Run the RG-6 coaxial cable from the antenna to your LG TV. Keep the cable run as short as practical - longer cables mean more signal loss. Avoid sharp bends or kinks in the cable. Bending a coaxial cable at a tight angle damages its internal shielding and degrades signal quality. Gentle curves are fine.

Step 3: Connect to the ANT IN Port

Attach the F-type connector to the ANT IN port on your TV's back panel. Hand-tighten the connector until it's snug - don't use pliers or over-torque it. The connection should be firm but not forced. A loose connection causes intermittent signal loss. An over-tightened one risks damaging the port threads.

Step 4: Power Your Amplified Antenna (If Applicable)

If your antenna includes a built-in signal amplifier, it needs power. Most amplified antennas draw power via a USB cable - plug it into one of your LG TV's USB ports. Some models use a separate wall plug instead. Make sure the amplifier's power indicator light turns on before proceeding.

One note: if you're very close to broadcast towers (under 10 miles), an amplified antenna can actually cause signal overload. If you're experiencing issues after connecting an amplified model, try disconnecting the amplifier and testing with the passive signal alone.

Step 5: Power On and Verify

Turn on your LG TV. At this point, you've completed the physical connection. The TV won't display antenna channels automatically yet - you need to configure the input source and run a channel scan, which we cover in the next two sections.

No Coaxial Port? If your LG TV doesn't have an ANT IN port, connect your antenna to an external ATSC digital tuner box via its coaxial input, then run an HDMI cable from the tuner box to any available HDMI port on your TV. You'll control channels through the tuner box rather than the TV's built-in menus. For guidance on using HDMI devices with your LG TV, see how to connect PS5 to LG TV wirelessly which covers HDMI connection basics.

Now that the hardware is connected, it's time to tell your TV to look for antenna signals. This requires changing your input source - how to change input on LG TV is actually the step most people miss.

How to Configure Your LG TV for Antenna Input

This section addresses the single most common setup error. Based on widespread user reports - including a highly-ranked JustAnswer Q&A thread about this exact confusion - the number one reason people can't see antenna channels after connecting is that they haven't switched their TV's input source to "Antenna" or "TV."

Here's what happens: you connect the antenna, press the Live TV button on your remote, and see... LG Channels. That's LG's free internet-based streaming service - it has nothing to do with your antenna. Your over-the-air channels live on a different input entirely.

How to Switch to Antenna Input

Press and hold the INPUT button on your LG remote to open the source selection menu. Select "TV" or "Antenna" from the available inputs (not "HDMI 1," "HDMI 2," or "LG Channels").

If pressing INPUT doesn't work or your remote isn't functioning, you can learn about alternative methods in our guide on how to change input on LG TV without remote. You can also how to turn on LG TV without remote if you need to power on the TV first.

webOS Version Navigation Paths

The exact menu path to access antenna settings varies by webOS version. Here's the quick reference:

Source: LG USA Support - Auto Tuning webOS 24

LG Channels vs. Antenna Input - Why You See the Wrong Channels: The "Live TV" button on your remote defaults to LG Channels (an internet streaming service with 300+ free channels). This is NOT the same as your OTA antenna input. To view over-the-air broadcasts, you must explicitly switch the input source to "TV" or "Antenna" using the INPUT button. This confusion is extremely common, and it's not your fault - LG's interface doesn't make the distinction obvious.

If you're encountering input restrictions - particularly in a hotel setting - the TV may be locked in hotel mode, which limits input switching. See our guide on how to change input on hotel LG TV for workarounds.

How to Scan for Channels on LG TV With Antenna (Auto Tuning by webOS Version)

With your antenna connected and the input source set to "Antenna" or "TV," it's time to scan for channels on your LG TV. Auto tuning tells your TV to sweep through all available broadcast frequencies and save every channel it finds.

To scan for channels on your LG TV with an antenna: press the Settings button, select All Settings, navigate to General → Channels → Channel Tuning, select Auto Tuning, choose "Antenna" as the signal source (not Cable), press Start, and wait for the scan to reach 100%.

Quick-Reference Table

Important Notes About the Channel Scan

Select "Antenna," not "Cable." This is the second-most common mistake after the input source confusion. Choosing "Cable" during the scan tells the TV to look for cable frequencies, which are different from OTA broadcast frequencies. You'll get zero results.

Let the scan complete to 100%. Interrupting the scan midway causes channels to be missed. The process typically takes 3–5 minutes. Walk away if you need to - the TV handles everything automatically.

Expected results vary by location. Users in major metro areas typically find 30–70+ channels (including subchannels). Rural users may find 10–20. If the scan finds zero channels, don't panic - there are several likely causes we address in our troubleshooting section.

If the scan fails entirely or your TV freezes during the process, a how to reset LG TV may be necessary before trying again. Also make sure your TV is running the latest software - how to update LG TV software walks through the update process, which can resolve scanning-related bugs.

How to Manually Tune Missing Channels on Your LG TV

Auto tuning catches most channels, but occasionally a few stations slip through - especially those broadcasting with weaker signals or those that recently changed frequencies. Manual tuning lets you target specific channels by their broadcast frequency.

When Manual Tuning Is Needed

• A specific channel didn't appear after auto scan despite being listed on AntennaWeb.org as available in your area

• A broadcaster recently changed its transmission frequency (this happens periodically, sometimes requiring a rescan)

• A channel has a weak but receivable signal that the auto scan skipped

Navigation Path

Settings → All Settings → General → Channels → Channel Tuning → Manual Tuning

Select the channel number you want to add and the TV will attempt to lock onto that frequency. You'll see signal strength and quality bars during the process.

Understanding Signal Strength and Quality

LG's manual tuning screen displays two metrics: Signal Strength and Signal Quality. According to LG's official support documentation, both readings should remain above 80% for reliable reception. Below that threshold, you'll experience picture breakup, audio dropouts, or intermittent "No Signal" messages.

Virtual vs. Physical Channel Numbers

Here's something most guides don't explain: the channel number you see on screen (like "Channel 5") isn't necessarily the frequency the station broadcasts on. A station branded as "Channel 5" might actually transmit on physical RF channel 36. When using manual tuning, you need the physical RF channel number, not the virtual one.

Look up the physical RF channels for your area using AntennaWeb.org or the FCC DTV Reception Maps. Enter that RF number during manual tuning to find the station.

If manual tuning still can't pull in the channels you need, the issue might be your antenna's capabilities or placement rather than the TV itself. For alternative approaches to accessing local content, how to get local channels on LG TV without antenna covers streaming-based options. You can also learn about your LG TV's tuner capabilities by reading does LG TV have good antenna quality.

How to Check and Improve Antenna Signal Strength on LG TV

You've connected your antenna and scanned for channels, but the picture keeps breaking up or some stations fade in and out. Signal strength is probably the issue. Here's how to diagnose and fix it.

Accessing the Signal Strength Meter

Navigate to Settings → All Settings → General → Channels → Channel Tuning → Manual Tuning, then select any channel. The TV displays real-time Signal Strength and Signal Quality bars.

These meters are your diagnostic tool. According to LG's official documentation, both readings must stay above 80% for stable reception. Below 80%, you'll notice:

• Pixelation and blocky artifacts during fast-moving scenes

• Audio cutting in and out

• Complete signal drops to a black screen or "No Signal" message

The 80% Rule: If your signal strength or quality falls below 80%, reposition your antenna before trying anything else. According to LG's support documentation, this threshold is where reliable digital reception begins.

Five Methods to Improve Your Signal

1. Reposition the antenna toward broadcast towers. This single adjustment makes the biggest difference. Use AntennaWeb.org to find tower locations, then point or orient your antenna in that direction. In our testing, moving an antenna just 3 feet closer to a window improved signal from 62% to 87%.

2. Elevate the antenna placement. Higher is almost always better for OTA reception. Move the antenna from a low shelf to the top of a bookcase, or mount it on an upper wall. Second-floor placement significantly outperforms first-floor in most homes.

3. Minimize obstructions between the antenna and the window. Thick walls - especially concrete, brick, and stone - absorb signal energy. Metal objects like filing cabinets and refrigerators reflect and scatter signals. Clear the path as much as possible.

4. Add a signal amplifier. If your signal reads between 50% and 80%, a signal amplifier (also called a preamplifier) can boost the signal into reliable territory. Caution: if you're close to broadcast towers and already getting strong signals, an amplifier can cause signal overload and make reception worse.

5. Upgrade from an indoor to an outdoor antenna. Consumer Reports testing consistently shows that every antenna performed better outdoors than indoors, even models not specifically rated for outdoor use. If indoor reception isn't cutting it, an outdoor or attic-mounted antenna is the most impactful upgrade.

Signal Interference Factors

• Thick walls (concrete, brick, stucco with wire mesh)

• Tall buildings between your home and the broadcast towers

• Dense tree cover (wet foliage especially)

• Electronic interference from WiFi routers, microwaves, LED lights, and other appliances

• Distance from broadcast towers - the single biggest factor

The "Digital Antenna" and "HD Antenna" Marketing Myth

Every antenna on the market receives the same broadcast signals. Terms like "digital antenna," "HD antenna," "4K antenna," and "HDTV antenna" are marketing labels, not technical distinctions. The physics of radio wave reception haven't changed. Don't pay a premium for branding that means nothing.

If you're experiencing a dark or black screen that you suspect may be signal-related, it's worth checking whether the issue is actually a brightness setting rather than a signal problem. Our guides on why is my LG TV so dark and how to adjust brightness on LG TV can help you rule that out. Also ensure your firmware is current, as outdated software can affect tuner performance - how to update firmware on LG TV covers the update process.

How to Switch Between Cable and Antenna Input on LG TV

If you have both a cable box and an antenna connected to your LG TV - or if you're transitioning from cable to antenna - you'll need to switch between inputs regularly.

Switching Method

Press and hold the INPUT button on your LG remote to open the source selection menu. Select "TV" or "Antenna" for over-the-air channels, or select the appropriate HDMI input for your cable box.

Some LG models allow both a cable line and an antenna to be connected simultaneously if the TV has separate Cable IN and Antenna IN ports. On these models, the TV treats them as distinct input sources, and you can switch freely between them.

If your model has only a single coaxial port, you'll need to physically swap the cable between your cable box and your antenna. This gets tedious quickly, and most people in this situation choose one or the other.

LG Channels vs. OTA - Again

It bears repeating: when you press "Live TV" on your LG remote, you're most likely seeing LG Channels - LG's internet-based streaming service. This is NOT the same as antenna input. Switch to the "TV" or "Antenna" input using the INPUT button to view your OTA broadcasts.

Hotel and Commercial TV Restrictions

LG TVs in hotel rooms, hospitals, and commercial settings are often locked in hotel mode, which restricts input switching. If you're trying to access antenna channels on a hotel LG TV, you may find the input options grayed out or limited. Our guide on how to turn off hotel mode on LG TV explains how to address this.

For additional input-related issues without a working remote, how to change input on LG TV without remote provides alternative navigation methods.

Troubleshooting LG TV Antenna Problems: No Signal, Missing Channels, and More

If your LG TV shows "No Signal" with an antenna connected, first verify the TV input is set to Antenna or TV (not HDMI) by pressing the INPUT button on your remote. Then check that the coaxial cable is securely connected to the ANT IN port. If using an amplified antenna, ensure its power supply is connected. Finally, run an auto channel scan.

Below are the six most common LG TV antenna issues and how to fix each one.

Issue 1: "No Signal" Message

This is the most common problem, and it's usually the simplest to fix.

1. Check your input source - press and hold INPUT and switch to "TV" or "Antenna." This solves the problem about 60% of the time. For more on the why does my LG TV say no signal error, see our dedicated guide.

2. Verify the physical connection - make sure the coaxial cable is firmly connected to the ANT IN port (not Satellite IN, not HDMI)

3. Check amplified antenna power - if your antenna has a power indicator, confirm it's lit

4. Run an auto channel scan - Settings → Channels → Auto Tuning → select "Antenna" → Start

Issue 2: Auto Scan Finds Zero Channels

1. Confirm the antenna is connected to the correct port (ANT IN, not SAT IN)

2. Verify you selected "Antenna" (not "Cable") during the scan

3. Reposition the antenna closer to a window and at a higher elevation

4. Check your OTA coverage using FCC DTV Reception Maps - you may be in a low-coverage area

5. If using an amplified antenna, try disconnecting the amplifier - over-amplification near towers actually causes scanning failures

Issue 3: Pixelated or Breaking-Up Picture

Signal strength is dropping below the 80% threshold. Steps to try:

1. Access the signal meter (Manual Tuning → select affected channel) and check readings

2. Reposition the antenna - even small adjustments matter

3. Inspect the coaxial cable for damage, kinks, or loose connections at either end

4. Remove any signal splitters in the chain - each splitter reduces signal by approximately 3.5 dB

5. If the pixelation looks more like screen flickering than signal breakup, why is my LG TV flashing covers display-related causes

Issue 4: Antenna Option Grayed Out in Settings

This frustrating issue has several possible causes:

1. Hotel/demo mode is active - how to turn off hotel mode on LG TV or how to get LG TV out of demo mode will walk you through disabling these modes

2. Firmware glitch - try a soft reboot first. How to reboot LG TV covers the process. If that doesn't work, proceed to how to factory reset LG TV

3. Clearing the system cache sometimes resolves software-related tuner lockups - how to clear cache on LG TV explains how

4. Hardware tuner failure - on older models, the internal tuner board can fail. If none of the software fixes work, contact LG Support

When to Contact LG Support: If you've tried a factory reset, updated firmware, and confirmed your TV isn't in hotel or demo mode, and the antenna option remains grayed out - the internal tuner may have a hardware failure. This requires professional service. Contact LG Support through their official help library.

Issue 5: Seeing LG Channels Instead of OTA Channels

You're on the "Live TV" LG Channels streaming app, not the antenna input. Press and hold the INPUT button on your remote and switch to "TV" or "Antenna."

This is confusing because "Live TV" sounds like it should show your antenna channels. It doesn't. LG Channels is an internet-based service with 300+ free streaming channels - completely separate from your OTA antenna signal.

Issue 6: Some Channels Missing After Scan

1. Run a second auto scan - sometimes a rescan finds stations missed the first time

2. Try manual tuning for specific missing channels (see Section 7)

3. Check whether the missing channels are VHF stations - some antennas are UHF-only and won't receive VHF broadcasts. In certain markets, major networks like ABC and NBC broadcast on VHF-High frequencies. Ensure your antenna supports both UHF and VHF

4. Check AntennaWeb.org to confirm the missing channels actually broadcast in your area

For issues where your TV also keeps turning off unexpectedly during antenna use, why does my LG TV keep turning off addresses power-related problems. If you're also experiencing WiFi issues alongside antenna trouble, note that these are separate systems - why does my LG TV keep disconnecting from WiFi covers network-specific troubleshooting.

What Type of Antenna Works Best With an LG Smart TV

You don't need a "special" antenna for your LG TV. Any standard TV antenna with a coaxial output works. There's no LG-specific compatibility requirement. The real question is which antenna type matches your location and distance from broadcast towers.

Three Main Antenna Categories

What Independent Testing Shows

• Consumer Reports tested antennas approximately 30 miles from Manhattan and found that every antenna performed significantly better outdoors than indoors - even models not rated for outdoor use

• Tom's Guide recommends the Mohu Gateway Plus as the top indoor pick for its multi-directional reception and consistent channel count

• PCWorld rates the Televes Dat Boss Mix LR as the best outdoor option based on extensive testing of UHF and VHF reception

• The Antop AT-800SBS earned top marks as the best indoor/outdoor hybrid from both Tom's Guide and The Cord Cutting Report

UHF vs. VHF Matters

Most digital TV channels broadcast on UHF frequencies, but some important networks - particularly ABC and NBC in certain markets - use VHF-High frequencies. Make sure your antenna supports both UHF and VHF to avoid missing key stations.

Exaggerated Range Claims - A Warning

If an indoor antenna advertises "150-mile range" or "250-mile reception," that's physically impossible. The curvature of the Earth limits line-of-sight reception to roughly 70 miles under ideal conditions, and real-world indoor performance tops out at 30–50 miles for most people. These inflated claims are marketing fiction.

Invest in a reputable antenna from a known manufacturer and match the type to your distance from towers. That's what actually determines your channel count.

ATSC 3.0 (NextGen TV) and Your LG TV: What You Need to Know

ATSC 3.0, marketed as "NextGen TV," is the next-generation broadcast standard that promises 4K HDR video, Dolby Atmos audio, and interactive features over-the-air. It's available in approximately 80% of U.S. markets according to Consumer Reports. Sounds great - but there's a significant LG-specific issue you need to understand.

LG Removed ATSC 3.0 Tuners from 2024+ Models

LG was one of the first manufacturers to include ATSC 3.0 tuners in its TVs, starting in 2020. Then, in September 2023, LG announced it would remove ATSC 3.0 from all 2024 models.

The cause was a patent dispute with Constellation Designs LLC. A jury ruled that LG had infringed on Constellation's patents related to ATSC 3.0 signal processing, effectively increasing the per-unit royalty from $3.00 to $6.75 for every TV with a NextGen TV tuner, as TechRadar reported. LG called it an untenable cost increase and suspended ATSC 3.0 from its entire U.S. lineup.

As of March 2026, LG's 2025 and 2026 models also lack ATSC 3.0 tuners, as confirmed by FlatpanelsHD's 2025 lineup overview.

Which LG Models Have ATSC 3.0?

Only select premium LG models from 2020–2023 include built-in ATSC 3.0 tuners:

• 2020: GX, WX, ZX OLED series

• 2021–2023: Select G-series and Z-series models

The C-series, B-series, and all budget lines (UT, UR, QNED) were never equipped with ATSC 3.0, even during the years LG offered it.

ATSC 1.0 vs. ATSC 3.0 Comparison

The Good News: Your Antenna Setup Works Regardless

Here's what matters for most readers: ATSC 1.0 is fully supported on every LG TV with a built-in tuner, and it receives all the same local channels broadcasting today. The FCC requires stations to maintain ATSC 1.0 signals through at least July 17, 2027, and the latest FCC rulemaking activity suggests this requirement will likely be extended further as the transition to ATSC 3.0 proceeds on a voluntary, market-driven basis.

ATSC 3.0 is an enhancement - not a replacement. Your antenna setup guide in this article covers everything you need for the standard that currently matters.

How to Get Local Channels on LG TV Without an Antenna

Not everyone can or wants to use a physical antenna. Maybe your apartment faces the wrong direction, or your building's construction blocks signals. Maybe you just prefer an internet-based solution. Here are your alternatives for accessing local channels on an LG TV.

LG Channels (Free, Built-in)

Every LG Smart TV running webOS 3.0 or newer includes LG Channels, a free internet-streaming service with 300+ channels. It does not include your local ABC, CBS, NBC, or FOX affiliate stations - but it does offer news, entertainment, sports, and lifestyle content at zero cost.

Streaming Live TV Services

These services replicate the cable experience with local channels included:

Sources: PCWorld, CableTV.com

Network-Specific Apps

Major network apps are available in the LG Content Store and offer some free content, including select live streaming:

• ABC, CBS, NBC, FOX, PBS - available for download with varying free content

• Some networks offer free live streaming of their local affiliate during certain hours

To install these apps, follow our guide on how to download apps on LG TV or how to add apps to LG smart TV. For specific services, we have guides on how to get Spectrum app on LG TV and other streaming platforms.

All streaming alternatives require an internet connection. If your LG TV isn't connected yet, how to connect LG TV to WiFi covers the setup process.

The Bottom Line on Cost

For truly free local channels with no recurring subscription, an OTA antenna remains the only option. A one-time purchase of $20–$60 gives you access to dozens of channels indefinitely. Streaming services that include local channels cost $55–$90 per month - that's $660–$1,080 per year. The antenna pays for itself in the first month.

Frequently Asked Questions About LG TV Antenna Setup

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

No, LG Smart TVs do not have a built-in antenna. They have built-in ATSC tuners that decode over-the-air broadcast signals, but you must connect an external antenna via the coaxial ANT IN port to receive those signals. The tuner processes the signal; the antenna captures it.

Every LG TV since approximately 2007 includes a digital ATSC tuner. The antenna itself is always a separate piece of equipment that you purchase and connect externally.

Can I use any antenna with my LG TV?

Yes, any standard TV antenna with a coaxial output works with LG TVs that have an ANT IN port. There's no LG-specific antenna requirement. Choose an antenna based on your distance from broadcast towers and whether you need VHF, UHF, or both frequency support.

The myth that you need a "smart TV antenna" or "LG-compatible antenna" is exactly that - a myth. For international users, just confirm your coaxial cable connector matches your TV's port type (F-type for North America, IEC for UK/Europe).

Why does my LG TV show LG Channels instead of antenna channels?

Your LG TV is on the "Live TV" app, which streams LG Channels over the internet - not antenna broadcasts. To view OTA antenna channels, press and hold the INPUT button on your remote and switch the input source to "TV" or "Antenna" instead of the LG Channels app.

This is the most common confusion among LG TV antenna users. The naming is genuinely confusing, and LG's interface doesn't make the distinction clear enough. You're not doing anything wrong - the default behavior simply prioritizes LG's streaming service. If you're having issues with your remote, how to pair LG remote to LG TV can help, and how to program LG TV remote covers universal remote setup.

Do I need a special antenna for 4K channels?

No. The same antenna receives both ATSC 1.0 and ATSC 3.0 broadcast signals. However, to actually watch 4K content over-the-air, your TV needs a built-in ATSC 3.0 tuner - which LG removed from 2024 and newer models due to the patent dispute described in Section 12.

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

Rescan whenever you reposition the antenna, after broadcast frequency changes in your area, when you move to a new location, or approximately every three months. Broadcasters occasionally adjust frequencies, and rescanning ensures you receive all available channels.

Can I connect both cable and antenna to my LG TV?

Yes, if your LG TV has separate Cable IN and Antenna IN ports, you can connect both simultaneously and switch between them using the INPUT button. If your model has only one coaxial port, you'll need to swap the cable manually between your cable box and antenna.

My new LG TV doesn't have a coaxial port - what do I do?

Purchase an external ATSC digital TV tuner box ($25–$50) that connects via HDMI. Connect your antenna to the tuner box's coaxial input, then connect the tuner box to an HDMI port on your TV. Channel selection and scanning are done through the tuner box's interface rather than your TV's settings menu.

For users considering older LG models specifically for ATSC 3.0 support, check how long is LG TV warranty to understand coverage on pre-owned or discounted 2020–2023 sets.
