Bill,
Your luck with the e-probe antennas does testify to "clean" locations,
both in terms of local wiring and lack of nearby AM broadcast signals.
My results haven't been as good at home, though they have been better in
the woods of Maine. Even up there, the loop approach usually wins.
If the limiting factor is atmospheric noise, then that should be in the
form of plane EM waves, with E and H equally represented.
Just a thought -- there's probably no free lunch with small antennas.
The vertical has less response at high vertical angles, but is
omnidirectional in the horizontal plane. The loop has high vertical
angle response, but less overall in the line of the nulls. I'll bet that
the two antennas have similar pickup of noise arriving from a wide swath
of sky.
