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.

==================================
Dear Ian, what has Moxon got to do with it?
He was the person who was being misquoted. In the first reply, I was
setting that record straight.
Without personal experience how do you know you are not plagiarising and
further propagating old-wives' tales?
Because, whatever else I read, I also do my own thinking.
If you have personal experience do you need anybody else's support anyway?
Just state the facts on your own authority.
Or do authors all belong to the same masonic club which adds nothing to
veracity?
Certainly not; most authors do value a cross-check on their own thinking
- and above all, a cross-check against reality.
I certainly do, because it's how I was trained.
The value of the major academic textbooks is that most of them have been
in the public domain for decades, and available for critique and
cross-checking and correction in later editions. If your own findings
don't agree with the pool of knowledge that's already out there, you'd
better have some strong reasons to hand.
In this respect, all amateur radio publications are in a lesser league.
They are still going through the process of critique and technical
clarification - marvellously accelerated by the Internet in recent years
- but they're not there yet.
(PS: I have only vaguely heard of Moxon in these newsgroups. Never read him.
Not the slightest disrespect to him, or her, intended.
Perhaps you should: Moxon was a lot like you in his methods and his ways
of thinking.
But my own reference
bibles are restricted to Ohm, Ampere and Volta.)
All three of whom are conveniently not available for comment.

For about 15 hours out of 24, I reckon.
But anytime after your first glass of the evening, and before my first
cup of coffee the next day, don't push your luck :-)
