: The tool will generate a list of stations, color-coded by predicted signal strength.
These modern tools have become the standard for cord-cutters looking to cut the cord and switch to an over-the-air TV antenna, as they instantly display "Callsign / Network / Location/ Channel/ Miles Away/ Direction/ Signal (quality)".
Always remember the golden rule of DTV: The map tells you what is out there, but only the rescan button on your remote control brings it onto your screen. dtv gov maps
: The predictions and signal strength calculations assume you are using a quality outdoor antenna mounted 30 feet above ground level . If you plan to use an indoor antenna, your actual reception quality may vary significantly. The guide works hand-in-hand with an official "Antenna Guide" which provides general information on antennas and shows the kinds of antennas typically needed to receive strong, moderate, and weak signals.
Current research (IEEE BTS 2024) advocates for: : The tool will generate a list of
| | Pre-repack (typical) | Post-repack | |---------------|--------------------------|------------------| | Channel | UHF 30-51 | UHF 14-36, VHF 7-13| | ERP | 1000 kW (UHF) | 250-500 kW (UHF) | | Required field | 41 dBμV/m | 41 dBμV/m (UHF), 48 dBμV/m (VHF) |
If dtv.gov/maps shows your local stations are in the "Weak" (red) zone, do not waste money on a $20 indoor flat antenna. You will need a high-gain outdoor antenna [4,5]. : The predictions and signal strength calculations assume
: Clicking on a channel name reveals its frequency, distance from your location, and the precise direction (heading) of the transmitter. Optimization Tips for Better Reception
To get the most accurate results from the DTV Reception Map, there are some important technical details and tips you should keep in mind.
