You appear to be extrapolating, if I see this correctly, that since all
of the radiation is believed to come from one end of the dipole, then
the rest of the antenna is merely acting as the necessary reactances and
resistance needed to obtain the proper feedpoint impedance at a given
frequency. True?

No. It's not true that all the radiation "comes from one end of the
dipole". Extrapolation from that mistaken premise will lead to invalid
conclusions.

Following that line of reasoning, if the need for the aggregate
reactances/resistances can be eliminated via superconducting elements,
one will have just a single point source of radiation. Or, what is
commonly known as an isotropic radiator. I suspect that the plasma
antenna fellows are contemplating this too.

And there's the first one. . .
