[TowerTalk] de-rating tower wind loading limits

[henry gillow-wiles]

I have a crank-up tower rated at 30 sq. ft. for a 50 mph wind. I have 20
ft. of chrome-molly mast with 4 ft. in the tower. I want to de-rate the
wind load for 70 mph. How do I do this and what effect does the mast have
on the wind loading limits of the tower? I want to put 8 sq.ft. near the
top of the mast and 8.5 sq. ft. at the top of the tower. Can I do this, or
am I dancing with disaster?

tnx,    Henry   KB7RTA
