Thanks for catching that, Dave! I certanly can't argue with Rudy N6LF, but those two /4 10' high elevated radials in my old 160m page made that inverted-L a "killer"* in an ARRL 160 contest about 10
My experience was not on top band BUT on a 80 meter 4 sq. initially I installed 4 gullwing elevated tuned radials for each of the 4 elements. The array played will but over time it became quit clear
I have taken the liberty to move Jim's most recent reply on the Common mode thread over here where it is more on topic Jim: True enough There is a work around however Dick Weber k5UI ( SK ..I think)
Yes, the antenna modelling is helpful, but by no means definitive. Several years ago I put up a top loaded vertical over a very limited buried radial field, 16 x 20 m. It worked, but nothing exciting
On N6LF web page you can find the QEX series on ground mounted radials. And there is a ton of discussion of this topic on the reflector as it seems to come up often (may be mixing it with the towert
