      Well, and you'd be right. Rohn BX is basically TV tower and has very 
little torsional resistance (it's for TV antennas, remember?). Anyway, bigger 
antennas will eventually beat up the tower resulting in the rotator plate 
breaking as well as cross braces popping off. 

     And they're real meat grinders when you have to work on them. Be real 
careful if you want to install one.
