How close to the airport can my antenna be before being subject to the restrictions Part 17?
A. It begins at about four miles from the nearest runway. Section 17.7(b) describes an imaginary surface above which notification and registration are required. It extends outward and upward at one of the following slopes: For a large airport (any runway length more than 3,200-feet), the slope is 100 to 1 for a horizontal distance of 20,000-feet from the nearest point on the nearest runway. For a small airport (longest runway length no more than 3,200-feet), the slope is 50 to 1 for a horizontal distance of 10,000-feet from the nearest point on the nearest runway. For a heliport, the slope is 25:1 for a horizontal distance of 5,000-feet from the nearest landing and takeoff area. Q. My neighbor has a landing strip on his property. Must I give notification to the FAA? A. Section 17.7(d)(1) says that notification is required where the airport is available for public use and is listed in the Airport Directory of the current Airman’s Information Manual or in either the Alaska or Pacific Air
