No, it's really more a matter of how the antenna is oriented relative to
the flow of the Earth's Chi.

We can look at the lowest impedance in particular antenna, which will have
higher impedance points elsewhere along its length. Looking at different
antennas or arrays we can have antennas with higher lowest impedance. Like
folded dipoles and loops. Would that not indicate and provide closer "match" to
free space impedance? Again, K8CFU measured that folded monopole "surprisingly"
gave higher field strengths than simple monopole radiator. Wouldn't that
indicate that there is something "wrong" (good) about higher impedance
antennas? Capture area reflected in here?
