Look in the ARRL Handbook, chapter 30 of the 2004 handbook has a table
called "Guy Wire Lengths to Avoid". I am sure this table can be found in
the older or newer versions of the ARRL Handbook. Fred

Subject: [TowerTalk] guy wire resonance
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.
