Radio line of sight in two taps: terrain, antenna heights, repeaters, towers.
Will my radios reach? Zenith LOS Scout answers in two taps.
Tap where one antenna is, tap where the other is, and you get a plain answer: clear, partly blocked or blocked, with the distance, the terrain between them and the antenna heights that would make it work.
Built for ham radio operators, GMRS families, Meshtastic and MeshCore mesh builders, repeater owners, preppers and anyone planning a radio link.
WHAT YOU CAN DO
• Check any path: tap two points (or search a place, or use your location) and see if it's clear
• See the terrain profile between the two antennas, with the radio "keep-clear" zone drawn in
• Find out how tall each antenna needs to be to clear the path
• Pick your band: GMRS, 2 m, 70 cm, 1.25 m, 6 m, Meshtastic 915 MHz or a custom frequency
• Spot real obstructions: towers, buildings, stacks, turbines and power lines near the path, with heights
• Turn on map layers: ham repeaters, Meshtastic nodes, MeshCore nodes, water towers and tanks
• Streets, satellite and topo maps
• My sites: save your towers, repeaters and nodes with frequencies, offsets and tones; import RepeaterBook and CHIRP CSV files; export to CSV or JSON
• Share a path or your sites by link, or share sites with your group
• Optional free account to sync your sites to all your devices (and delete it any time, right in the app)
• Works without an account. No ads.
Results are estimates from public elevation and obstruction data. Always confirm with a real on-air test.
