I believe that may be a giant leap you are making to assume that the
top of the 45G will support 20 square feet in a 90 mph condition. If
you are going to make a leap like that, why did you not address the
loading of the various feedlines Rohn allows for on their design?????
Personally I would be very scared to make that quantum leap and
assumption because I do not believe it is correct.
