Ground radials for vertical antennas
The key to an efficient vertical antenna is a good ground radial or counterpoise system. In this video from Callum McCormick (M0MCX) we get a few suggestions on how to design, install, and test an experimental ground radial system.

Here are some comment from Callum: I have made a decision made to cut 32 radials at 10m long. That's 4 wavelengths of radials for 80m band - my lowest target frequency. At 40m, that's 8 wavelengths and for 20m band, I am running 16 wavelengths! I should be OK. Callum.
