Paul,
You said a mouthful and I couldn't agree with you more.
In 1996 @ CY0AA and 1997 from CY9AA (at the bottom of the cycle) we were
working JA's
with an A3S @ about 10' off the ground, and an R7000 about 3' off the
ground. Granted the signals weren't very strong
but we still did it.
Given a choice, I'd always take the higher antenna though. It seems to be
the "better" one about 90%+ of the time, despite
propagation mode.
73 es CU in the pileups.
