[TowerTalk] Tower Mast Wind Loading

[Mike Ryan]

Ed, While in lived in the D.C. area some years ago, I had a 160ft stick of 
Rohn 45 with a similar mast as you described. Eight feet of my 24ft mast 
were in the top section which employed 2 thrust bearings and a T2x rotator. 
Above was a 4 element monobander for 17, a Hygain 204BA, and a HyGain 
Discoverer 3 (3 ele 40mtr monobander). That worked well for me for the 9 
years I lived there.  -Mike

"Really? I never heard this rule of thumb before."

It was always what I learned.  And seems to make sense from a moment arm
standpoint.



I would be interested in what others do in their designs.
