Phillystran is a non-conducting guy material. It's made up of Kevlar
strands covered by a PVC jacket. It is manufactured in sizes that are EHS
equivalents and does eliminate any antenna-guy wire interaction. I use it
myself and feel that it contributed to the success of my 20M stack.
It is fairly expensive compared to EHS wire guys but it's worth it if
you're planning a populated tower with other antennas hanging from it.
The only amateur supplier is Texas Towers. BTW, you'll need the special
Phillystran Preformed guy grips as well.
