Antennas pick up over-the-air broadcast channels that are available in your area. This typically means local networks like NBC, ABC, CBS, and Fox, along with a few dozen other stations. Channel availability, however, can drastically differ depending on whether your community is more rural or urban.  One way to check available channels in your community is through the AntennaWeb tool. Just enter your address in the search bar and a list of channels that can be picked up in your area will show up in the results.
