Does this include nylon antenna supports, which have a considerably longer
path to ground, as well? I was considering using nylon electric fence
standoffs to support a horizontal loop, figuring that if they supported
several miles of 20,000 V electric fence on steel posts okay, they would
support an 80m horizontal loop with negligible loss. Or are the old fashion
ceramic standoffs a significantly lower loss but not as mechanically
convenient way to go?
