This may not be comparing apples to apples but here's my question after
studying the two towers.
US Tower HDX-89 claims 9.2 sq ft of max allowable antenna wind area 90
mph 3 second gust
Tash DX86 claims 21 sq ft of max allowable antenna wind area 85 mph 3
sec gust
After looking at both designs they both start with a lower section that
is 28.75" wide and a top section that is 13 7/8" (Tash) and 13 15/16"
(US Tower)
So the designs appear to be the same, why are the allow able antenna
wind loads so different? I realize that one is based on 90 mph the
other on 85 mph. Does the 5 mph delta add up to a 11.8 sq ft difference?
Thanks in advance.
