The tool provides a comprehensive technical overview of the broadcast landscape for any specific U.S. address or zip code:
dtv.gov/maps is an indispensable instrument in the American telecommunications landscape, providing a standardized, scientifically grounded reference for digital television coverage. It successfully translates complex propagation physics into an accessible format for the public. However, users must recognize that the tool provides a theoretical prediction based on outdoor reception and idealized terrain data. For optimal utility, the maps should be viewed as the first step in a site survey, not the final verdict on reception capability. As the broadcast standard evolves, the methodology behind these maps must evolve to maintain relevance in a mobile, IP-driven media environment. dtv.gov/maps

Click on the call letters of your favorite networks (e.g., ABC, NBC, CBS). The map will show where those towers are. If most towers are in one direction, a directional antenna pointed that way is often best. However, users must recognize that the tool provides
The most significant limitation of the FCC model is that the propagation contours are typically calculated for an outdoor antenna at a height of 30 feet (roughly equivalent to a standard two-story rooftop).

The maps integrate detailed terrain elevation data. Because VHF and UHF signals are heavily influenced by topography (shadowing by hills, diffraction over ridges), the accuracy of the map is directly tied to the resolution of the topographical database used by the FCC. The tool identifies "Line of Sight" versus "No Line of Sight" scenarios, which are critical for UHF reception.
