My Elecraft rigs are connected to guyed, end-fed half wave vertical monopole antennas, one each on 30 meters and 40 meters. I use tapped-L-parallel-C matching networks at the base of these antennas, which are ground mounted and insulated.
They radiate at the horizon, or darned close to it, and don't need any inconvenient ground radial wires, or even a particularly low impedance earth. To me, that fact alone was worth any other effort. I got inspiration for my antennas from similar designs used at the following addresses ... each have historical markers, incidentally ... if you are curious, you can use Google Maps to see them yourself: 764 Tylersville Road, Mason, Ohio 8068 Concord Road, Brentwood, Tennessee While the hams who designed and installed these antennas had bigger budgets than I do, they had the same goals. For portable use, if you can manage an overhead tree branch at a suitable height, only 60 feet of wire interrupted in the center with 47 microHenrys of L yielded a center-loaded EFHW I used *very* successfully on 80 meters. Again, no radials needed, a major consideration to me. The feedpoint impedance was quite high, so the matching network I had to make was interesting but still do-able.
