The Best Indoor TV Antennas

So much about indoor antenna use comes down to location, from where you place the antenna in your home to where your home is geographically located and which broadcasts are available in your area. Before purchasing an antenna, I highly recommend checking out AntennaWeb.org, which can help determine which channels and what kind of broadcast quality and features you can expect.

If you live in a rural location, you may want to consider a high-powered outdoor TV antenna or other digital live TV alternatives and so-called cord-cutter options like YouTube TV or Hulu with Live TV, as even the best indoor antennas may not help. Many smart TV systems from brands like Samsung, Roku, LG, and others offer free digital channels online, including news, sports, and reruns—lots and lots of reruns—from across the TV landscape.

For most areas, local channels are available in a mix of SD (Standard Definition) and HD (High Definition) at 720p or 1080i. All digital antennas also support the latest ATSC 3.0 standard which allows for “Nextgen” TV channels, including support for modern features like 4K UHD resolution, HDR and Wide Color Gamut, and audio formats like Dolby Atmos. To take advantage of ATSC 3.0 broadcasts on your TV, you'll need a model with an ATSC 3.0 tuner (many TV brands have begun dropping this excellent feature so check before you buy), as well as a local broadcaster that supports the standard.

ATSC 3.0 is still in its early stages, and has been rolling out slowly. In our Oregon test area, ATSC 3.0 is available only in a limited fashion, though the channel list has been growing, with intriguing options like an HDR pickleball channel (seriously). Only a modest number of national broadcasts support features like HDR or 4K UHD resolution at present. To see if ATSC 3.0 is available in your area, you can peruse this map and check out the Nextgen TV website for more info.

Your indoor antenna success rate and channel availability depend not only on your broadcast area, but also your home's local terrain, layout, and other circumstances. After you've discovered which TV stations are technically available in your area, you'll want to locate your home's antenna sweet spot. This will take some trial and error, but a good rule of thumb is to set your antenna at or near a window facing your primary broadcast transmitters, as walls and other objects can cause interference.

When in doubt, raise your antenna higher. All the antennas we tested come with around 10 to 12 feet of reach, and you can easily extend that by purchasing some cheap coaxial cable. While some antennas are “unidirectional,” all the antennas we chose are omnidirectional, designed to pick up signals from multiple stations and areas.

The short answer is: maybe? We tested both amplified and older plug-and-play reference antennas in multiple areas, including in the middle of a moderately sized metro area and several miles outside it. Overall, we found mostly minor differences in the available channels or broadcast quality, though the pricier amplified antennas tended to get more channels (even if most weren't super enticing). The difference may be more evident if you live 30-plus miles outside a broadcast area, or it might not, depending largely on geography and your position to broadcast towers. That said, most antennas currently available come with amplification.

Most amplified antennas we tested claim a 50- to 60-mile range from transmitters, but your mileage may vary. In some cases, amplification may even distort signals if you're too close to the broadcast area, though we didn't notice any such issues. Amplification can be turned off, but we got fewer channels when turning off amplified antennas than when using non-amplified antennas in the same area. As noted above, your first step is to check for what's available in your area with a site like AntennaWeb.

One of the most notable findings in our testing is that the number of channels each antenna picks up may vary wildly between channel scans with (and sometimes without) a modest change in position. That's especially true for the Nextgen channels. All digital antennas should technically be able to receive Nextgen channels when tested with a TV/tuner that supports ATSC 3.0, though even some premium brands have dropped or added ATSC 3.0 support between model years.

As we continue to test (and retest) models, we've noticed an increase in avaialble options, including a 50% increase in available Nextgen channels over the last year. One other point worth noting is an antenna's onboard signal meter didn't always equate to better reception. So the best moto for channel scanning is, to borrow a childhood idiom, try, try, and try again.

If you start going down the antenna rabbit hole, you may find broadcast channels and antenna models listing UHF (ultra high frequency) and VHF (very high frequency) support. Essentially, all broadcast channels are separated into either the higher-frequency UHF band (where most modern digital channels reside) or VHF. VHF is generally a stronger signal over longer distances, but UHF is better for obstructions like buildings, and UHF channels are better optimized for the digital era. While some TV transmitters still use VHF, the majority of today's over-the-air TV channels broadcast over UHF. For most people it's not something to worry about. While most of the models on our list technically support both bands, they're likely to be optimized for UHF. You can find out more about UHF vs VHF here.

One reason you might have trouble receiving channels is local interference which can be caused by everything from rough weather to cars driving by your reception area. If you're suddenly missing some channels or not getting as many as you expected, local interference may be the culprit. This is one reason we do multiple tests and scans over several days to ensure the best signal for evaluation. Because of the frequencies used in OTA broadcasts, antennas are generally unaffected by broader phenomenon like solar storms.
