Been experimenting with ground plane configurations on my homebrew 20m vertical and getting conflicting advice. 76.5 is the recommended angle for achieving an impedance of 50 ohms when using a single elevated radial. 45 degrees is recommended when two or more or used. Some sources insist on 4+ radials while others claim single radial works fine.
Currently running SWR of 1.02 with one elevated radial at approximately 76° angle. Performance seems decent for DX but wondering if I'm missing something. As long as you install at least 60 ground radials, it will work well enough for DX to keep your Amateur Radio enjoyment up for a long, long time - but that seems excessive for elevated systems.
