[TowerTalk] Mast loading

[ersmar at comcast.net]

TT:

     I'm considering changing out my GP-15 and D40 on my tower this spring 
for some V/UHF Yagis.  I used Frank Travanty W9JCC's article on tower and 
antenna wind loading (QEX July /Aug 2001) as my main reference for the 
calculations.  Based on the methodology in that article, I'm well within the 
safe limits of my Trylon T-500-64 tower and CM mast, even at 90 mph winds, 
for my proposed antenna configs.

     However, I think I recall a recent posting here (within the last month 
or so) that warns about a math error in Frank's article.  Did I recall 
correctly?  Or was that some other article that has error(s)?  The archives 
are no help in that there are so many recent postings on tower loading (kind 
of like drinking water from a fire hose.)

     Thanks for any help here.
