Is there a correct pull ?
Easy answer to your question.
Go by whatever Rohn recommends for the guy wire. If you use 3/16 inch EHS,
you should have approximately 390 lbs of force on it. If you use 1/4 inch
EHS, use approximately 670 lbs. If you use 5/16 use around 1100 lbs. Just
whatever the book recommends for guy wire and you should be fine.
It is possible to use too heavy a guy wire and the 10% figure would actually
be trying to pull the tower apart. An extreme example would be using 5/16
on Rohn 25 and using 1100 pounds of pull on it...not too smart!
