     Hank is quite right. Of course the TIA and UBC calculations are done 
differently so that's part of the problem. The tower manufacturers run into 
this too since they are more compliant with the TIA. I have a letter from 
Rohn (around here somewhere) stating that for their purposes, they comply 
with the UBC as well. (This is a broad statement of my recollection - lawyers 
and engineers will certainly have their input.)
