[UK-CONTEST] UK-Contest Digest, Non-conductive ropes for guying

[G3RAU at aol.com]

The number of insulators you would need is quite high.  Lets take  a 80ft 
Versatower guyed at 4 levels with 3 guys at the recommended 40ft  radius. 
 
The guy lengths are 78ft, 65ft, 53ft & 44ft.  If as has been  posted you 
break up at 38ft, that means 2 in the top tier and 1 in each of  the lower 
tiers.  That adds up to 15.  If you have a problem  with 12M interaction then 
you need to break up at 14ft and the number  rockets upwards and becomes 
silly.
 
The HD 80ft Versatower, when guyed as per mfrs instructions, uses  plastic 
coated 5mm steel guy cable rated at 350KG . Any insulator up  there needs to 
have a bending radius large enough not to weaken the guy when it  is looped 
back to secure it.  Using a small insulator and kinking  the guy is 
probably a recipe for disaster !
