Discussions that have appeared from time-to-time about the advisability of
having a local (1/4 wl) radial ground plane beneath antennas like the
vertical dipole led me to wonder what some systematicew model might
indicate. Such modeling, of course, does not automatically indicate
reality, since a whole range of questions regarding the adequacy of NEC-2
and NEC-4 for dealing with ground planes at or just atop the ground are
undergoing extensive analysis at present.
However, it seemed useful to at least get a picture of what the modeling
outcomes would be. So I started phase 1 of a study and have placed the
initial results at the site under the title above, with the item listed
near the very bottom of the section of items on modeling.
I hope the information is useful to someone.
