So you move the loading coil from the base of the antenna to inside the tuner in the
radio (with some coax in between). How does that affect the radiation

The "tuner" is really a matching network that maximizes the power that
the output stage can get into the transmission line. Current
distribution in the antenna is determined by the boundary conditions --
that is, gotta be near zero at the ends of the intentional radiator and
the counterpoise.
