*****************
I've received a number of excellent treatises on the subject. Mike's
response points out several important issues--all of which are omitted in
the glossy brochures from tower manufacturers. Now my concern is to be able
to compare the various manufacturer's specifications to make a realistic
comparison.
E.g. US Tower boasts of huge loadings at 50 MPH. I get 50 MPH many times a
year. Twice in the last two weeks! The 50 MPH rating is a JOKE! Other
manufacturers, like Rohn, will rate them at 70, 80, 90, even 110 MPH.
Making a realistic comparison is difficult unless you have the blueprints
and know how to read them...
Short of hiring a PE, what's a tower owner wanna-bee to do?
