Antenna Structure Registration (ASR) - Help

This site includes information about registering antenna structures in the FCC’s Antenna Structure Registration (ASR) system. An antenna structure must be registered if the antenna structure is taller than 200 feet above ground level or may interfere with the flight path of a nearby airport.

On May 9, 2012, the FCC released a Public Notice that provides guidance on the implementation of the environmental notification process for the registration of antenna structures. The environmental notification process applies to new tower registrations and to certain modifications of registered towers that may have a significant environmental effect. We have created a series of help articles to help you understand the environmental notification process. Please review the help articles under the topics Environmental Notice Process and Filing a Request for Environmental Review.
