You are using that principle of impedance substitution whenever you
calibrate your antenna impedance bridge using known values of resistORS,

Yes, but I comprehend what I am doing. For you to imply the "electrical
properties don't change" between a 50 ohm dummy load and a 50 ohm dipole
antenna is simply ridiculous.

That whole principle relies on the fact that, at the same frequency and
in the steady state, the "definition of impedance" in terms of its
electrical properties does *not* change. That's the whole point.

The electrical properties *can* change and that's the whole point. The
electrical properties of a 50+j0 dummy load and a 50+j0 antenna are
almost completely different.

A transmission line can transfer photons. Can a lumped constant L-C
model transfer photons?
