Its been shown on here and elsewhere, by many and many times, that once
beyond a modest radial field the field strength goes up marginally to the
classic 128.
Ive stressed many times that a mesh screen out from the base 50' or so for
160 does more for the signal than going from 32-64 or 64 to 128 radials. It
also stabilizes the all important maximum current area so that climate
doesnt have much effect.

But, Carl, there may be other variables changing in the system, for
example, the amount of moisture in the ground. So it's not a controlled
experiment.

Every autumn (when the fluid is leaving the trees) and every spring (when
the fluid is coming up again) I have to go out and adjust the phasing in
my
2 el phased vertical for 160m. So some kind of effect does high trees
have
on the antenna.
