This interactive map shows TV signal coverage across the continental United States. The data is computed using terrain-aware RF propagation modeling with SRTM elevation data for 593 million grid points (~160m resolution).
Tips:
- Use the network selector to view coverage for specific TV networks
- Toggle 3D terrain to see how mountains affect signal propagation
- Click "My Location" to center the map on your position
- Tilt and rotate the map with right-click drag or Ctrl+drag
