[TowerTalk] guy wire resonance

Fri Dec 23 08:17:24 EST 2005

I am replacing some guy wires on a 70' Rohn 25 with a 40m beam. What is the spacing between the insulators so the guys are not resonant? The guys are 3/16" EHS and I am using the 500D insulators. I lost 3 guys due to ice storm last week, the Phillystran was cut in half on the top 2 guys but the bottom guy with all steel cable was undamaged. It was the 4000lb Phillystran.
