I mostly agree. Years ago, I had a half-wave vertical for 20 meters, with 4 elevated radials, and that's how I fed it. I used to work VK's and ZL's nightly with it from my old QTH in NW Ohio. [snip]

I'm certainly not trying to argue with you, Dick; perhaps I'm way off base. I'm not an antenna expert. Why don't we see what the others on the Topband list have to say about the radial requirements f
I'm not sure that perfect ground is the same as "lots" of radials, where "lots" is 60 half wave radials. You are modeling, I measured real antennas. The measurements were done on 20 meters, so there
Quarterwave & Halfwave verticals: Theory and simulation say that a halfwave vertical will work almost as well with a ground rod as with a good radial system. My tests at 20 meters between a halfwave
