I test TV antennas. Follow these steps to pick the right one for you

TV antennas are having something of a renaissance in the U.S. Buoyed by the ever-increasing costs of cable and streaming subscriptions, and additional channels enabled by the advent of digital TV, roughly one in five U.S. homes now rely on an antenna for their television. Beyond the cost of the antenna, all the channels are free, and you might even get a better picture than through a pay TV service.

When it comes to choosing an antenna, the selection is almost as wide as the programming you can receive, but if you do a little homework, you should be able to buy with confidence and ensure a good picture.

We’ll walk through the steps required to figure out what kind of antenna you need and what you might receive, then you can use PCWorld’s buyer’s guide to help narrow down your choices when you’re ready to shop.

The first step is figuring out what TV programming is available where your live.

What can I tune in with a TV antenna?

The quantity and selection of TV channels depends on where you live. In general, the closer you are to a large metro area, where the broadcasters’ towers are generally located, the more channels will be broadcast. In rural areas, the opposite is typically the case. If you live near the Canadian or Mexican borders, you might be able to receive additional channels from those countries.

Most parts of the U.S. have access to the four major commercial networks (ABC, CBS, Fox and NBC) and a local PBS station. Many of these stations broadcast additional digital networks dedicated to a particular theme, such as children’s shows on PBS Kids and classic TV on MeTV, Cozi, and Antenna TV.

To figure out what’s available, we recommend navigating to Rabbit Ears. This website models TV reception based on the location of the antenna and TV transmitter data from the Federal Communications Commission (FCC). The Signal Search Map page is where you need to be.

1. Enter your address (street, city, and state)
2. When the map updates to show your house, click “Move pushpin to center of Map View” in the panel below the map
3. Set the approximate height your antenna is above ground level
4. Click “Go”

The site will display its best prediction of the TV channels available in your location, along with an estimate of the strength of their signal levels (higher numbers are better). Take a look at the channels and networks and figure out what you want to receive; make a note of the predicted signal level.

As a rule of thumb, an indoor antenna will be sufficient for channels with a good signal level, an attic or outdoor antenna will likely be required for stations marked fair, and a larger outdoor antenna with an amplifier will be required for those marked poor. Stations marked as bad will likely be difficult to receive without extreme measures.

Finally, take a look at the direction of the transmitters from your location. If they are all in roughly the same direction, a single antenna should be fine. If they are wide apart, an antenna on a rotator—a motor that can turn the mast the antenna is mounted to to change the antenna’s orientation—might be required, especially if the signals strengths are poor.

Choose an antenna

Now you’re armed with everything you need to make an informed decision. PCWorld’s antenna picks are divided into several categories, from cheap indoor antennas to substantial roof-mounted ones. In general, an outdoor antenna will always deliver the best performance, no matter the signal level. They’ll provide much more reliable reception than indoor antennas, which are always a compromise.

That said, not everyone can install an outdoor antenna, so we have several indoor antennas, from basic, thin antennas that can be put in a window so better amplified antennas that should provide a step up in reception.

A further level up are smaller outdoor antennas, many of which can easily be installed on the side of a house, on a balcony, or inside an attic space.

Many of these are also amplified. Finally, we have tested a number of roof-mounted antennas that are the gold standard in TV reception. A roof-mounted antenna will provide the most reliable reception and should pull in the greatest number of channels. If you are planning to install one yourself, please use safety precautions when on a roof and ensure the system meets local building code requirements, especially for grounding.

Warning! Don’t believe the claims

If you browse online shopping sites or look at the advertising for antennas, you’ll see lots of dubious claims.

The first rule is to ignore anything about antenna range claims. Reception depends on a multitude of factors, including the transmitter frequency and power, the location of the transmitter, the immediate environment around your house, and more. There is simply no way an antenna can guarantee its claimed number of miles. Use the method outlined above, that takes all these factors into account.

The second thing to remember is that there’s no such thing as an HD, 4K, or NextGen TV antenna. An antenna simply receives signals and isn’t dependent on the format being broadcast, so ignore those claims as well.

PCWorld’s antenna reviews are conducted under real-world conditions with the same equipment and at the same location, so we can give an honest and measured comparison of every antenna we test.

Attention renters, HOA residents, and apartment dwellers

If you rent a house or apartment or live under the terms of an HOA (Homeowners Association), don’t let anyone tell you you cannot install a TV antenna. In the U.S. federal law gives you the right to do so under the FCC’s “OTARD” regulations. In short, you have the right to install a TV antenna for reception of local broadcast signals in an area you rent or have exclusive access to. If you’re facing resistance, read the FCC page, linked above, and quote the OTARD rule.

Connecting the antenna to your TV

Martyn Williams/Foundry

Most indoor antennas come with a small cord attached that can be connected directly to a TV or amplifier, if one is supplied; other antennas might come with a cable or require you to supply your own.

TV antenna cable is called coaxial cable, or coax for short. It has a center wire that carries the signal, a plastic insulator, an outer braid that shields the center cable from interference, and an outer sheath protects the cable from the elements. The standard for TV antennas is called RG-6.

It’s important to use a good quality coax because cables result in signal loss. You can minimize this by using a good cable and keeping the length as short as possible. If you need to run a very long cable, consider an amplifier, ideally at the antenna end of the connection.

And that’s how to choose a TV antenna

That should be everything you need to choose and install a TV antenna. TV reception is mostly a science but can be a little bit of an art; so, if you don’t get satisfactory reception, go over the steps again. Try moving the location of the antenna to see if that improves picture quality. If you get a lot of interference, consider adding an amplifier.

Most of all, don’t give up! A good antenna will provide thousands of hours of free entertainment for many years, so invest a bit of time and money into getting it right.
