This article provides information on filing an application to register a replacement antenna structure in the Antenna Structure Registration (ASR) system. A replacement structure replaces an existing antenna structure at the same geographic location. Registration of a replacement antenna structure does not require Environmental Notice .
An antenna structure cannot be considered a replacement if any of the following conditions apply:
- The proposed antenna structure uses a less preferred FAA Lighting style than the existing antenna structure. Lighting styles are ranked as follows (with the most preferred lighting style listed first and the least preferred listed last):
- No lights;
- FAA Lighting Styles that do not involve use of red steady lights; and
- FAA Lighting Styles that involve use of red steady lights.
- The proposed antenna structure will result in a substantial increase in size compared to the existing antenna structure. A substantial increase in size occurs if:
- The proposed antenna structure would be more than 10% or twenty feet (whichever is greater) taller than the existing antenna structure;
- The proposed antenna structure would involve the installation of more than the standard number of new equipment cabinets for the technology involved, not to exceed four, or more than one new equipment shelter; or
- The proposed antenna structure would be more than twenty feet wider or more than double the width of the existing antenna structure at any height, whichever is greater.
- The proposed antenna structure will require excavation more than 30 feet beyond the edge of the existing antenna structure property and any existing easements.
If any of these conditions is met, the proposed antenna structure needs to be registered by filing a New Antenna Structure Registration (insert link).
