false?

The broadside radiation is mostly horizontally polarized
while the radiation off the ends is mostly vertically
polarized. I wonder if that would make a measurable
difference?

I think polarization will play in the picture. Dealing with NVIS, we do not
get much of the polarization being rolled around as with signals coming from
refractions/reflections via ionosphere.
The signals at the receiving end would be coming from "above", but I would
suspect that with distinct polarization component that should be detectable
with receiving antenna if rotated.
So I would vote that there would be difference in NVIS signals most likely
characterized by sharp minimum at the opposite polarization receiving
antenna orientation.
Any RF signals have a distinct polarization at any point and time.
Add some constructive or destructive interference and one would get the
picture.
