Don't know from personal experience, but Les Moxon, author of HF
Antennas for all Locations, seems to believe it creates an advantage.
You might want to read his thoughts on that.


The advantages of which Moxon wrote are for *horizontal* polarization
only. If the antenna height above ground is correct, the ground
reflection can reinforce low-angle radiation in the downslope direction.

But Moxon also shows specifically that there are *no* such advantages
for vertical polarization. The ground-reflected ray is lost at a high
angle.
