I've used the LJE (Lance Johnson Engineering) Radial Plates for some of my HF
Vertical antennas. I've been trying to find a link to order another one, but
haven't been successful. Does anyone know where/how to order one? They were
very convenient.

Subject: [TowerTalk] Solid 160 radial plates?
I've been reading a lot of older threads about using ground shields (mesh or
solid copper ground radial plates) at the base of an Inverted L for 160.
Several contend that AM broadcast stations use copper shielding at the base
feedpoint with radials attached around the perimeter as currents are max there.
Even the length of the radials becomes a question as one thread says the
velocity factor of radials on the ground is 0.50 and the at the proper radial
length, for on ground/slightly buried radials, is more like 80 feet and not one
quarter wavelength. Buried radials do not need to be resonant so my question
centers more on the use of a solid, or mesh, material at the base. Comments on
this practice please?
