I sense there's still a failure to communicate.

If Dale means by "V/U" VHF and UHF, ground wave isn't a viable means of
propagation anyway. The attenuation of ground waves increases with
frequency, to the point that they're virtually useless at VHF and above.
So at those frequencies, I'd think the polarization choice for short
range communication would be based on how it affects attenuation,
multipath, and QRM. Given those criteria, horizontal might well have an
advantage for short range communication, in some locations at least. And
it's long been favored for long range VHF/UHF communication.


Ground wave is a broad term, but it is how VHF and UHF usually propagate.
Ground wave is a general term for several means of propagation. Surface
wave is what you are really talking about when you mention Ground wave.
Space wave, atmosphere ducts and other means near the earth are all part of
the Ground wave term. The Sky wave is usually the broad term for
reflections off the ionosphere and other reflected modes from high above the
surface.

For vertical or horizontal there is very little differance in which is used
at VHF and above. Noise is usually vertical polorised so horizontal for the
RF is usually used . Vertical is used so the simple vertical moble whips
could be used for all around coverage.
