[TowerTalk] Tower loading calcs have changed?

[Mickey Baker]

Hi, Jack,

The method of calculating windload HAS changed and the requirements of
building codes have changed to reflect the newer EIA standards. No use
repeating what someone else has done a nice job explaining.  K7NV helped me
to understand at his web site about this:
