[TowerTalk] Grounding tower guy wires

[markrob at mindspring.com]

Don't you have your metallic guy wires broken up into smaller lengths to avoid rf resonances and the resultant distortion of your directional hf antennas. People normally do that. That being the case then I cannot see how you can ground your guy wires. Comments?
