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.

I wasn't talking about skip either- the majority of V/U weak signal work is
extended ground wave via perhaps enhanced tropo.

1.Horizontal polarity can take advantage of ground gain reflection that
vertical polarity cannot.

2. In addition, at 900 MHz where a wavelength is just over a foot, even
mounting the antenna at 12" would place the first lobe at 15 degrees,
assuming the car roof completely determines this- and I doubt that it has
much of an effect on far field take off angle.
