I'm exploring the possibility of putting up a radio tower on a property I own. The problem is that my property is roughly 1,000ft from a private airstrip. The location that I want to put the tower is not within the approach/departure path of the runway and is not under any navigational easements. The height that I'm looking at is roughly 150ft, just high enough to get approximately 20-30ft above the existing trees in the area. My question though is, what are FAA restrictions around building towers near private airports? Is it different from public airports? If so, is it possible to do this at all so close to an existing airport?
According to this AC you dont need to light the structure,
Any temporary or permanent structure, including all appurtenances, that exceeds an overall height of 200 feet (61 m) above ground level (AGL) or exceeds any obstruction standard contained in 14 CFR Part 77 should be marked and/or lighted.
But the FAA does have special cases and since you are close to a strip they may require/recommend it,
The FAA may also recommend marking and/or lighting a structure that does not exceed 200 (61 m) feet AGL or 14 CFR Part 77 standards because of its particular location.
Looks like you need some specific stuff to actually light it. Your local FSDO should be able to help out with what ever info you need. As far as I know these kinds of regulations don't change between public and private airports.
You can find the letter of the law for 14 CFR Part 77 here. The most applicable to your case is quite possibly,
(3) A height within a terminal obstacle clearance area, including an initial approach segment, a departure area, and a circling approach area, which would result in the vertical distance between any point on the object and an established minimum instrument flight altitude within that area or segment to be less than the required obstacle clearance.
Even though you are not directly in line with the runway you may be in conflict with a potential traffic pattern or approach segment.
