[TowerTalk] Straightening 45g tower base

[W0MU Mike Fatchett]

That is with the load at the top of the tower.  If he mounts a rotor and 
has a 20 ft mast I think things could change pretty quickly?

As such, and if this is true, the wind load, per Rohn specs, is: 110 mph 3 sec gust exp B 35 sq ft and exp C 22 sq ft. If it's std 45 G, won't take 110 gust. At 90 mph 3 sec gust, its rated at 4.9 sq ft. And I think someone should run the figures again on how much it would be off over 40 foot. If it's off 1" at the top of the short base, well my common sense says it off more than 4" at 40 foot. (But then I am old and senile)
