I am installing a 40 foot tower. It will not be self supporting. It will be bracketed to the roof/wall, and I will use guy wires. The tower is in 10 foot sections, and is about 50 pounds per section.

I believe the 45G is only rated for 40 or 50 feet self supporting with a small tribander. Even in the smallest tribander would not be safe at 40-50 feet on freestanding Rohn 45 at the 90 MPH rating.
