[Elecraft] HF Verticals?

[Stuart Rohre]

Earl, there have been a number of papers on improved radio locations from
operating from elevated ground.  I wish I could remember the paper, but
there is one I have seen with the ray traces to show the signals
improvement.
The signal can go from the antenna toward ground, but if on a hill, the
reflection happens at lower ground and they get a nice low angle of takeoff
on the reflection, lower than the flat ground case.
Locally, NT5C has had much good success from his hill, compared to my valley
location.

The paper I remember, had both operating measurements and modeling of the
paths, supported by the operational experience.  Sorry I cannot remember
where I saw it, but might be QST or CQ, or QEX,  even Communications
Quarterly.

We see the same thing in sonar measurements off reflections in a depression
below the sonar source.
It is proven Physics.
