Can a Rohn 25G be safely self-supporting at ~ 40' with a house bracket at
15', or must it be guyed? The beam will be a 10 lb. Mosley 3el mini-beam
with only 2.5 sq ft of wind surface area.

My "25G Bracketed Towers - No Ice" chart shows 7.7 Sq Ft at 90mph for a
bracketed 40 ft tower. It lists two brackets, one at 30 ft and one at
15 ft. It is not clear to me whether this is an either/or situation
involving one bracket or a two-bracket configuration. It's Rohn DWG#
