[TowerTalk] Guying a Rohn Tower

In an 80 MPH area (like that of NE0P), the 2 sq ft. for 
Rohn 45 with 34' above a bracket is not enough to support 
much of anything.  With 24' above the top bracket, Rohn 
25 is rated for 4.9 ft. sq. and Rohn 45 is rated to 9.3
ft. sq.  

Note that the Rohn specifications call for two brackets 
*AND* a rigid concrete (not pinned) base.  The second 
bracket is placed 50% of the height of the top bracket.
