The Antenna Registration Structure (ASR) program requires owners of antenna structures that are taller than 200 feet above ground level or that may interfere with the flight path of a nearby airport to register those structures with the FCC. The antenna structure owner must obtain painting and lighting specifications from the Federal Aviation Administration (FAA) and include those specifications in its registration prior to construction. The ASR program allows the FCC to fulfill its statutory responsibility to require painting and lighting of antenna structures that may pose a hazard to air navigation.
The Commission's antenna structure registration, marking and lighting rules are located in 47 C.F.R Part 17.
You can register an antenna structure, search existing registrations and more at the FCC's Antenna Structure Registration (ASR) system.
