RadioDig unifies the FCC Antenna Structure Registration database, FAA obstruction filings, and FCC license records into one fast, current map — right on your phone.
Search any tower by call sign, ASR number, address, or place, and see who's licensed to transmit from it, its height and coordinates, and its FAA status. Search a U.S. state by name and RadioDig zooms out to show the whole state at once.
