Hello David.
Your setup sounds very similar to what my friend described to me,
although the topic of our conversation was 160 meter antennas. It's
entirely possible I misunderstood that he was talking about a radial
system for an 80-meter antenna that could be adapted to 160.
As you mentioned, it still seems the most important point is to get as
much wire, mesh, fencing, etc., on the ground and connect all of it to
multiple ground rods at the base of the antenna. Very few hams have the
capability of building textbook vertical antenna installations on 160
meters due to the physical constraints of their property. In the real
world, even big-sig DXers and contesters have to adapt to the conditions
presented to them by their surroundings. With 160 meters, for most of us
it's a case of making the best of the situation . . . whatever that
situation may be.
BTW, David, I'm a new YCCC member and I've seen your posts on the club
reflector. It's nice to run into you here, too.
