What, Coililng the wire has nothing to do with how well it does or does not
radiate, only with how the radiation is summed into the total field. The
current distribution in a loading coil should be very similar to the current
distribution in the secton of antenna it is replacing.

Actually, coiling the wire tends to reduce the far-field radiation
because much of the near-field(s) cancel each other. The currents
on each side of the coil are traveling the opposite direction in
much the same way they do in a transmission line. However, that
doesn't mean the currents at the bottom and top of the coil are
identical. The magnitude of the total current at the bottom and
top of the coil depends in large amount on the phase shift through
the coil.
