Yep, and once the issue of size versus efficieny is put to rest, it would
not be a bad idea to look at the real effects of ground, both in terms
of height in wavelengths and soil quality.


Thankyou. This is the bit I am most weak on (though I did not grasp all
the
previous detail, the ground loss was an issue not lost on me, and is the
one I need most to solve in my next efforts). What is this NEC program,
and
where can I find it? Sorry, but I have to ask, or Google will likely flood
me
with Nippon Electric Company details.

Me too. It has been extremely useful in identifying promising approaches
without having to build the hardware for each.
