What is the primary purpose of antenna structure registration (ASR) with the FCC?

The primary purpose of Antenna Structure Registration (ASR) with the FCC (Federal Communications Commission) is to ensure aviation safety by providing a centralized database of antenna structures that could pose a hazard to air navigation. By registering antenna structures that meet certain height and location criteria, the FCC can identify potential obstructions in navigable airspace. This information is then used to coordinate with the FAA (Federal Aviation Administration) to determine if marking and lighting are required to make the structure more visible to pilots. The ASR process helps to prevent collisions between aircraft and antenna structures, contributing to the safety of air travel. It also allows the FCC to manage the radio frequency spectrum effectively by understanding the location and characteristics of transmitting antennas.
