[TowerTalk] Wind loading

[Gary Smith]

I'm having to play games with setting up eight, short, active 
vertical elements on an incredibly rocky area. I am not able to drive 
in ground rods, much less the base of the antennas. I'm coming up 
with a plan to make wooden bases for them and hold them down with 
rocks. 

Since I live on the ocean's edge and have to contend with hurricane 
force winds every so often, I'm trying to figure out the wind loading 
of the verticals I'm considering. I'll buy the aluminum sections from 
DXE and prefer to use larger sections just because of branches 
falling at the marsh edge, as they always do. But thicker pieces will 
have more wind loading and that is a problem.

If I use the thinnest configuration I'll have about 22 feet tall made 
of .375, .5, .625 & .750 sections.

I asked what the wind loading would be and nobody I talked to was 
able to give me a clue. Does anyone know a formula to figure the wind 
loading of tapered elements?

Thanks & 73,

Gary
