Thanks again Bill!  
Yeah, I've looked at the info at Texas Towers. The EHS and the galvanized wire 
rope look pretty much the same as far as strength.  I've order 500' of the wire 
rope.  I may try to acquire enough of the kevlar rope to use at the very top of 
the 51' tower.  I have an A3S with the 743 40 meter addon atop the tower. Since 
I live on the Gulf Coast - I don't think I can "overguy" the tower. <grin>  
So, do you mean the insulators should be at 27' or less or more than 27'?

i would recommend EHS as well.  also the rule of thumb for the insulators is 
~27ft. so i heard.  I used and recommend  using phillystran  (Kevlar rope) made 
for guy lines combined with EHS at the bottom.   see more info at

Does anyone have any idea if 3/16 7x19 galvanized "aircraft cable" with a burst 
strength of 4200lbs would be OK to use instead of EHS for guying a 51' rohn 25 
with a cushcraft A3S/743 40 meter adon antenna sitting atop ?  Also, is there a 
"rule of thumb for dumbies" as how to not have the metal guywire resonance 
on HF - (ie how far apart do you place those glass eggs? Do all the guywires 
need them, or just the closer ones to the antenna?) Thanks in advance de K5MLC
