[TowerTalk] Rohn 25 & Mast lingth

[Jim Brown]

I'm not a structural or mechanical engineer, but from my courses at the 
beginner level in those disciplines 50+ years ago, it seems to me that 
how much mast is needed within the tower depends on what is above the 
tower on that mast, how long that mast is, and the wind loads.

If you're an ME and have done the calcs, I'll certainly defer to your 
advice.
