I believe that one of the major advantages of the aramid guys is the enormous
weight reduction over steel cable. Has anyone ever calculated and published
the plus delta in allowable load on Rohn tower when synthetic guy cable is
used?
I also highly endorse the torque arm stabilizer assembly for the top of any
tower with a reasonable load. I have a TA45 on my 70' Rohn 45 tower because of
the erratic ridge winds we have from the eastern Sierra's. It really added
significant stability and rigidity to the tower.
