We have been told that lumped inductors have zero phase shift.

I think the claim is that there is zero current differential in
magnitude across a lumped inductor. It's certainly true of a pure
inductor. Presumably, one in which radiation is not a factor, and for
which the electrical length is short compared to wavelength.

For a lumped inductance, the electrical length is zero. Presumably,
that has a zero effect on the current. Assuming that only the voltage
is affected, the phase relationship between the voltage and current
is blown compared to an unloaded antenna. But the relationship is
somehow (magically?) restored by the time the end of the antenna is
encountered. Exactly how is that relationship restored?
