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.

This will be sad news to all the V/U weak signal ops who have consistantly
covered long distances using horizontal polarity.

This fellow was planning to put his antenna on the roof of a car.
Presumably he is *not* DXing.

I was therefore speaking of groundwave coverage, not any kind of skip,
and what I stated holds true; for local groundwave, vertical is best.

DXers, on the other hand, use horizontal precisely because the local
groundwave coverage is poor, thereby reducing local QRM but having
little or no effect on skip signals.
