However, the point that the OP was trying to make was that it is likely
that superconductive radiating elements could establish the need for a
serious rethinking of antenna theory.

Actually, the only reason I mentioned superconductors (and thanks to Roy
for putting me straight on that point!) was to examine a vanishingly
short dipole without worrying about losses. I was not trying to alter
existing antenna theory.
