Jim,

I don't have the measurement capabilities that some of you folk have,
so I'm just using EZNEC as my "experimental equipment". I'm being
assured that it's representative of what I would see "for real", and
it's easier pressing keys than building new test equipment Are you
suggesting that "real world" current measurements would be
significantly different than the EZNEC predictions?

I gather from your response that you feel the Corum model is
inappropriate for the "bugcatcher", but you're not advocating an
alternative? That's the part I struggle with - if a model gets close
(albeit not perfect) to predicting "real world" performance, and
there's no other alternative being put forward, I don't see the reason
for rejecting it so forcefully?

Hi Steve,

Personally, I think some actual measurements would help enormously in
formulating/evaluating a model. Otherwise all we have is hand waving
and proselytizing.

You know quite a bit about antennas, Steve, so you should know the
answer to the following:
1. Mathematically, what does MoM do?
2. Why would anyone use MoM if there were a set of symbolic equations
that would work just as well?
3. When are we going to see the Corum-Moore method in the textbooks?
