Make sure you know what the wind ratings are for your area before getting
excited about a particular tower. Manufacturers assume you live in the most
favorable place. Wind rating for my tower location turned out not to be 90 Mph
but 130Mph! (Ridge crest/Slope etc).
73!

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.
