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. 73, Stuart K5KVH

In the Ham literature, there is an excellent article by Al Christman,
KB8I, "Elevated Vertical Antenna Systems, published in the August, 1988
QST. That article also appeared in the ARRL publication, "Vertical
Antenna Classics". This article is a Ham-oriented version of Christman's
"Vertical Monopoles with Elevated Ground Systems," published in the
Proceedings of the Third Annual Review of Progress in Applied
Computational Electrodynamics by the Naval Postgraduate School,
Monterey, CA, March 1987.
H. L. Ley, Jr., N3CDR, did some very enlightening and interesting
experiments comparing a short loaded counterpoise to an elevated ground
system. He published his findings in "A Multiband Loaded Counterpoise
for Vertical Antennas" that appeared in "The ARRL Antenna Compendium,
Vol. 2" as well as in "Vertical Antenna Classics".
