Reception maps for digital television are available on the Federal Communications Commission's website, located at fcc.gov. The website allows users to search for digital television signals that are available at a specific location.
The reception maps on the Federal Communications Commission's website display and calculate signal strength based on assumptions of utilizing an outdoor antenna placed 30 feet above ground level. Due to this generalized calculation, the reception level actually experienced indoors may vary drastically. The website allows users to search for digital television reception by city, state, zip code, or street address. After searching, detailed information on the nearby towers providing digital television signals is available.
