[TowerTalk] Shortened Guy Leads On R25G

[jknodel M Knodel]

Thanks for the help with my previous questions regarding the crankups.  Here 
is my next question.  I would appreciate any thoughts I could get on it.

I am planning on putting up a 60' (actually about 61.5' with the BPL25G top 
thrust bearing plate) Rohn 25 tower.  I will have one 3 element SteppIR beam 
with the 30/40m dipole option on it.  This antenna is 8.1 sq. ft wind load 
and will be placed just a couple inches above the thrust bearing (no long 
mast on top).  The 60' tower is rated at 10.2 sq. ft. windload for 90 mph 
(my area windspeed).

I would like to place the downguys at a shorter distance than the 80% 
spec'ed by Rohn.  I surveyed my property and calculated (with AutoCAD) that 
I can get guy leads of 41.28' (69% of 60', 67% of 61.5').  Do you think guy 
leads at 67%-69% instead of 80% would be safe?  Thanks for any help on this. 
  I appreciate it.
