Sometime during the planning stages for a proposed new antenna structure (tower, pole, water tank, wind turbine, windmill), a Search Ring Analysis is performed to determine best location for FAA and FCC ASR permitting and licensing. The analysis is quite detailed, involving a central latitude/longitude with ground elevation and proposed overall structure height. Information for the study is usually acquired through a Site Acquisition or an RF Engineering firm. The study examines ten points in a 0 to 360 degree circumference and three to ten miles out from the central location. The 360-degree radius search captivates:
- All existing registered FCC ASR structures, structure type and overall height.
- Public-use landing facilities (airports) within the search ring perimeters.
- The nearest runway at each studied location.
- FAA notice criteria for each location which includes 100:1 (airport runway more than 3,200 ft.), 50:1 (airport runway no more than 3,200 ft.) or 25:1 (heliport) runway slope and Part 77 notice standards.
- A recommendation depicting best location within the search ring for the proposed new antenna structure.
The resulting information is compiled into a detailed report and presented to the Site Acquisition team responsible for acquiring leased property for the proposed antenna structure. The team will initiate leasing negotiations with the property owner(s) in the search ring. Once a lease has been generated, the state and federal permitting and licensing process for the new structure can begin.
The Search Ring Analysis may expose the most advantageous location impacts air navigation by failing runway slope or exceeding other FAA Part 77 notice standards. At that point, a decision will be made to pursue state/federal permitting in spite of the risk or relocate the proposed structure to a less risky place.
