[TowerTalk] bracketed 55g

[Jim Rhodes]

The Rohn web page has a table at:

http://www.rohnnet.com/CommPro/Towers/Bracketed/Bracketed.htm

That should give you an idea. A 90 foot tower with the top bracket at 66 ft 
has a 90mph rating of 16 square feet with the top bracket 24 ft down. A 50 
foot tower with the top bracket 14 feet down has a 90mph rating of 39.4 ft. 
Since Yellow Medicine Co. is in an 85mph zone that should give you an idea. 
Sounds pretty good
