SignalScout - Cell Tower Map

SignalScout puts every registered cell tower and antenna in the United States on one clean, fast map — straight from public FCC records.

Whether you're checking what's broadcasting near your home, scouting coverage, researching a property, or just curious about that tower down the road, SignalScout gives you the real data behind the signal.

WHAT YOU GET
- 159,000+ towers: A nationwide map of FCC Antenna Structure Registration records, bundled for instant browsing, even offline.
- Smart clustering: Towers group together when zoomed out and snap to individual pins as you zoom in, so the map stays fast everywhere.
- Filter by owner: Screen for Verizon, AT&T, T-Mobile, US Cellular, DISH, the big tower companies, or local utilities. SignalScout matches their real legal entity names, so "Verizon" also finds Cellco Partnership and GTE Mobilnet.
- Full tower details: Tap any site for owner, height, structure type, status, registration date, and a link to the official FCC record.
- Satellite view: Switch to satellite imagery to see the actual terrain, rooftops, and structures around each site.
- Search anywhere: Jump to any city, address, or place, or recenter on your current location.
- Add towers you spot: See a tower that isn't on the map? Drop a pin and save it. Your additions are clearly marked as your own and stored on your device.
- Favorites & units: Save towers you care about and switch between feet and meters.

FREE FOR EVERYONE
Everything in SignalScout is free — every tower, every detail, no ads, no subscriptions, nothing locked. If the app helps you, an optional tip jar in Settings lets you support development with a one-time tip of any size.

WHERE THE DATA COMES FROM
- Registered towers: U.S. FCC Antenna Structure Registration (ASR) database.
- Cellular antenna sites: FCC Universal Licensing System via HIFLD Open Data.
- 5G NR cells: OpenCelliD (optional, with your own free API key).
