Open-ended antennas like dipoles are standing wave antennas. The
forward current is relatively constant through the coil and the
reflected current is relatively constant through the coil. But
the phasor sum of those two currents can vary wildly from end
to end in the coil because of phase shifts.

Don't we have a case of coil being RF choke to certain extent?

RF chokes are usually high enough impedance to drop virtually all
the RF voltage across the choke.

Also I think that behaviour of radiator before and after the coil defines the
magnitude of the current, no?

It can be thought of as a very lossy transmission line where
the loss is radiation. Please see my other posting comparing
a 1/2WL dipole to a loaded dipole.
