I put up a 20 meter vertical with closely
spaced radials 4 wavelengths long spread over about
60 degrees centered on Europe. I A/B'ed it
with an ordinary vertical. The vertical with the
long radials had an advantage of perhaps 3 dB
vs the ordinary vertical toward Europe (a
just discernable difference). In other directions,
it had no advantage. Not what I would call
gangbusters.
