[TowerTalk] W-51 wind load

[Neil]

Good morning,

Can someone shed some light on why Tashijan tower's WT-51 is rated for
13 sq. ft. of load for 3 second gust @ 85 mph, while my Triex W-51 is 
only rated
for 9 sq. ft. of antenna load @ 50 mph?
The only difference that I can see, looking at the PE drawings, is the  
Tashijan tower
required a bigger concrete base, which is the base I poured , 3 x 3 x 
6'deep.
Very interested to hear what others feel is a safe loading of this Tower.
Also, I want to re-cable the tower, I am thinking of going from 3/16" to a
1/4" cable, does anyone in the Tri-state area (NH-VT-MA) have a 1/4"
swaging tool I could use? I really hate to spend $300+ for a tool I will
probably only use once or twice in my life......
Thanks....
