Topband: Guy wire insulators (was Thunderstorm)

[w8av at aol.com]

 I work in the broadcast industy and we have used the the light "blue-grey" insulators in steel guy wires on many AM broadcast stations over the years.  Although we primarily use Phillystran for AM tower guying applications anymore, I have never heard of a non-rf transparency issue with these insulators and we have never had a problem using them.
