Important Warning: If you are using an indoor antenna placed on a TV stand, your reception quality will likely be than the map predicts, because the FCC's model assumes an outdoor, elevated installation.
The tool immediately populates a list of local television stations. It also displays a dynamic map showing your location relative to the broadcast towers. Understanding the Signal Strength Color Codes
: TV channels are split into Ultra High Frequency (UHF, RF channels 14–51) and Very High Frequency (VHF, RF channels 2–13). If the tool shows your favorite local stations are distributed across both bands, you must buy an antenna explicitly specified as a VHF/UHF combo antenna .
The map provides estimates based on a "terrain-sensitive propagation model". It assumes your antenna is outdoor and 30 feet above ground level, so indoor results may be weaker. dtv gov maps
While dtv.gov is the primary source, the data is used by the wider community:
The website dtv.gov (which redirects to the official FCC landing page) was established during the landmark transition from analog to digital television broadcasting in the late 2000s. The goal was to help consumers understand the massive shift in technology and coverage.
The map uses complex models that consider terrain (hills, mountains) between you and the transmitter to predict signal strength. Important Warning: If you are using an indoor

Click on the of a station. If the station changed frequency during the repack, the map lists the date (known as the "repack date") when viewers needed to rescan their TVs to continue receiving the signal. If you open the map and your antenna shows no signal for a station you used to get, the tool will instantly tell you if it was due to a frequency change.
This tool will analyze your location to determine which broadcast television signals are available in your area. It will compute t...
