Roy,

My program requires antenna gains relative to isotropic to be entered.
To help discover where I was going wrong a numerical type program was
needed. Numerical programs do not need the intervention of fallible
human ideas about isotropes, mirror images and ground reflections.

I did not realise that EZNEC has the ability to calculate voltages and
currents induced in elements miles away from the radiating element.

There's a limit because of numerical precision, which I cautioned about
in my last posting. But this problem is within its capabilities.

But having the correct answer, I still have a problem. Praps you can
help me to solve it.

Yes, I'm very interested by the apparent contradiction. But I'm also
seemingly getting some contradictory answers -- I'll have something to
offer after I get it sorted out.
