The phase shift along the coil plus the phase shift along antenna
conductors does NOT add up 90 degrees when the antenna is 1/4-wave
resonant. It is not anywhere near to it.

The first problem is that the phase shift along the antenna is about
zero. Having the phase shift along the antenna and coil add to 90
degrees would require a 90 degree shift of current phase across the
coil, regardless of the size of the coil or the antenna. Only the
inductor in an EH antenna drive system has that magical property. I
assume you have to empty the internal coulomb bucket periodically, but
I'm sure that's proprietary.

Pluck a guitar string and watch it oscillate. Notice that all parts of
the string reach their maximum and minimum excursions at the same time.
There's no delay from one point to another. Same thing happens on a
(standing wave) antenna or a shorted or open transmission line, and for
the same reason.
