Exactly how is the physics of the Rhombic changed by
adding a termination resistor?

The same physics applies to all antennas, Cecil. Would you assert
that fact gives all antennas the same characteristics?

But here's the point. Your claim is that the coil as you have modeled
it, performs the same in EZNEC as it does when it is employed as part
of a 75 meter Bugcatcher antenna. At the same time you want to claim
that there's no other way to do such testing.

It's not a reasonable viewpoint, Cecil. But you're entitled to it and
I'm happy if you want to go on having it. :-)
