Over-the-air TV has been around for years, and it’s built right into your TV — all you need is an antenna. Local channels broadcast in your area provide sports, news and TV shows from ABC, CBS, Fox, NBC, PBS and more with excellent HD image quality. It’s no wonder that OTA is one of the first stops for anyone looking to cut the cord or supplement their streaming diet.

The best part is the price: absolutely free. Unlike cable or live TV streaming services, antenna broadcasts don’t require you to pay any ongoing fees, and if you live in an area with decent reception you can get OTA TV with an indoor antenna for less than $20 all told. In other parts of the country you may need to spend more on an outdoor antenna.

Antenna TV is simple to get set up. Here’s where to start.

Indoor antennas are so inexpensive that my best advice is to just buy one, connect it to your TV and see what channels you pull in. I reviewed the top indoor antenna models from Amazon and found that the best in an urban environment is the Channel Master Flatenna. In my testing I found that the number and strength of channels didn’t increase in a poor coverage area when replaced with a more expensive model, even with a gain amplifier. In other words, if the cheaper internal antennas don’t work, it’s likely nothing similar will. That’s because your location is the single biggest factor in whether or not you get reception — your antenna tech is a distant second, at best.

If you’re having trouble getting reception, you might get some improvement with an outdoor antenna. They cost more, however, and are significantly more difficult to install, because they typically require access to a roof or an attic and you may require professional help.

We haven’t tested external antennas at CNET, but highly rated ones from Amazon and tech site Tech Hive start from $60. Try to get an antenna compatible with both UHF and VHF, for while most channels have moved to UHF with the advent of digital transmissions, some legacy stations are still using VHF.

Tips for installing an antenna

Given the complexity (and potential dangers) of installing a roof antenna we’re going to stick with internal antennas for this article. Here’s what you need: 

Most modern indoor antennas are flat and designed to be installed high on a window, preferably facing in the direction of a broadcast antenna. How do you determine which way that is? 

In addition to selling its namesakes, Antennas Direct is also an excellent cord-cutting resource and offers maps based on your location, as well as the direction of the nearest antennas. Keep your compass or Google Maps app handy!

Some antennas include adhesive strips for mounting but if yours doesn’t, you’ll need masking tape or poster putty. Try not to use duct tape, as it can mark your walls or windows. 

Install the antenna as high as you can because neighboring houses and buildings can block TV signals. Experiment with placement — if a window doesn’t work, try a wall as it may give you better reception. Try to keep the antenna away from magnetic metals such as security bars and radiators if possible.

Many indoor antennas have a long, detachable coaxial cable, but if your TV and best reception placement are too far away, you may need a longer cable. Once you have enough slack in the cable, connect the spare end of the coaxial cable to the back of your TV or DVR. Screw it in nice and tight. Finally, you can now set your tuner to scan for available channels.

Whether you’re using the tuner built into your TV or an external box such as TiVo, you’ll nevertheless receive OTA TV as a digital signal: analog signals were switched off in 2009. In the Settings menu of your device, you should find either a Channel or Tuning section, and from there you should be able to activate an Auto setting. The tuner on the TV or DVR will then find all of the available channels, and if it’s got a program guide it will then arrange all of the upcoming shows into a grid for you.  

If you live in an area with good reception you’ll be able to get at least the major network channels and their affiliates, including your local PBS station. Depending on where your house is you may have some issues due to natural or man-made obstacles, and searching for a problem channel on Google can tell you if it’s a common one.

In addition to the Antennas Direct site mentioned above, the FCC maintains a DTV Reception Maps page where you can enter your address and find the channels available in your area. It grades each station according to frequency as well as signal strength but it won’t tell you which direction the antenna is in.

If you live in a poor reception area you could try a model with a built-in amplifier. But be aware that this can overload your tuner and you could end up with a lot less channels. If you have a model with an amp, try it without first. 

Because you’re receiving digital signals, instead of analog ones, you won’t get snow in the case of suboptimal reception. If you have poor to no reception, you’ll either get a jumpy or pixelated picture or nothing at all, just blackness.

Finally if you get a good picture and decide you like using antenna TV, you might want to invest in an antenna DVR. It will allow you to schedule and record shows for playback later, skip commercials and even stream your antenna TV outside the home.

Will I need a new antenna for Next Gen TV?

Next Gen TV, aka ATSC 3.0, is the next-generation version of free OTA TV, rolling out in select areas of the country now and over the next few years. Among other improvements it supports 4K HDR video and an internet back-channel which is used for on-demand video and usage data. 

To get Next Gen TV you won’t need a new antenna. That’s the good news. 

The bad news is that you will need a new TV or external tuner box. TVs with Next Gen TV tuners are just starting to arrive and they’re mostly expensive, and only a couple of tuner boxes are available now.

In other words, your cheap antenna will be useful for a long time.
