Hi John,

In fact a larger disk will actually raise the launch angle - hardly a
satisfactory mirror analogy.


the "mirror" produces (half of the) photons that the
full dipole would have produced.


Photons? This is CecilBabble. Mirrors as "productive" sources of
photons demonstrates the failure of analogies.

Do you deny the photonic nature of radio waves?

I just realized that the sentence you quoted s easily misinterpreted.
When I said "the "mirror" produces (half of the) photons that the
full dipole would have produced." I meant that half as many photons
are produced, compared to the full dipole antenna that produces the
same fields above the center line. I didn't mean that the mirror
produces half of the total photons that are radiated.
