Yes, vertically polarized signals also undergo ground reflections;
however the reflection coefficient magnitude and phase are very
different to those of a horizontally polarized signal, which is why the
horizontally polarized signal picks up more "reflection gain"
My reading of all the papers is that 4 *very accurately tuned radials
away from perturbations* can be as effective as many ground radials; but
now try to achieve that for a multiband vertical. Seems to me that
ground radials are much more "forgiving".

Verticals are sometimes claimed to not have ground reflections in the
near field (as Billy C suggests in his post), but I thought there ARE
ground reflections - at least in the far field ... something having to
do with the Pseudo Brewster Angle...
