      Morgan County, AL, is only a 70 MPH windspeed zone so you're off the
hook for big winds.

     What you need is the MARC Program - the Mast, Antenna and Rotator
Calculator. Plug in the wind speed and the above information and it'll TELL
YOU exactly what you need - mast material, wall thickness and yield strength
required. It's only $9.95 + s/h from TOWER TECH, Box 572, Woodinville, WA,
