    I couldn't agree more. Unfortunately there is WAY too much tower between 
the housebracket and the guys - 42 feet. The Rohn specs call for 32-34 feet 

    Why do I suspect that the guys were NOT 3/16" EHS like the specs call 
for? Just a wild guess on my part.

    They do well for amateur installations in spite of the many short-cuts 
and back-of-the-envelope engineering hams are well known for.

    I did - it's wrong. I just posted more specific information on "Tower 
Buidling (sic) 201".
