The results page generates a list of stations. Do not just look at the channel number; look at the in dBm (decibel-milliwatts) or the color code:

are currently updating to include ATSC 3.0 "Lite" signals (simulcasts). When you use the map, look for stations marked with "ATSC 3.0" or "NextGen." The coverage patterns for 3.0 are often different (and generally slightly weaker range) than legacy ATSC 1.0 signals.

Technically, the value of DTV.gov maps lies in their ability to account for propagation modeling. Radio frequency propagation is influenced by numerous variables, including topography, antenna height, and interference. A generic coverage circle drawn around a tower is insufficient because it fails to account for hills, valleys, and large buildings that can block signals. The FCC’s maps utilize sophisticated Longley-Rice methodology to predict signal behavior over irregular terrain. This technical precision ensures that the predictions are reliable, providing a trustworthy standard that third-party websites and apps often reference. It transforms the invisible and abstract concept of radio waves into a tangible, visual data set. dtv gov maps

If you’re relying on an over-the-air antenna for free TV, knowing which channels you can actually receive is critical. That’s where the come in.

Provided by the Federal Communications Commission (FCC), this interactive mapping program allows you to enter your address or zip code to see which over-the-air digital television (DTV) signals are available at your specific location.

After setting up or moving an antenna, you must re-scan for channels on your TV to capture the available signals. Alternative Resources Technically, the value of DTV

: Most TVs manufactured after 2007 have a built-in digital tuner.
