Hi Ed,

Efficient? A vertical has almost no Near Vertical radiation for Near
Vertical Incidence Skywave. You can get along with "almost no," or
you can simply use a low horizontal which would exhibit "a lot of"
Near Vertical Incidence Skywave.

Good ground, bad ground, radials, no radials won't change efficiency
much for the vertical's incidence overhead (there's a hole in that
pattern).

Richard,

By "efficient" I was referring to the transfer of power.... to a
presumed 50 ohm antenna input, not to any radiation characteristics !
As I understood it, a half wave vertical can give me this, with a
little effort. I also understood it to have a fairly high take off
angle.... which will certainly give me better in-state coverage than a
good low angle takeoff would..... wouldn't it?

Yes, I know a proper NVIS antenna would be far better than this....
that is why I used the term "some NVIS" characteristics.
