Hi Gregg, at one time there were guy plans for Rohn Towers used for  
Broadcast antennas. Those guy plans showed 60% guying radius.
 
Not sure if these drawings are still published but you might try a google  
search.

I am  planning to put up 130 ft. of Rohn 25 to be used as a 160 meter
vertical.  There will be no antennas on this tower. The Rohn spec for guy
anchor  points is 80% or 104 ft. 
I am looking for some guidance.  Getting 3 guy points each at 104 ft. from
the tower is going to be  challenging due to terrain and property lines. Are
there any guidelines for  anchor placement for a tower that does not have to
be subjected to  additional loading from an antenna? 
Any feedback is greatly  appreciated.
