A loading coil does not need to radiate to produce significant
difference between the current at its ends.

The same power may be produced at various impedances. The product of the
real voltage and the real current must be the same in all cases for the
same power.

A loading coil experiences a different voltage to current ratio
(impedance) at every point along its length.. This is due to the
combination of forward and reflected volts and amps. Because of the
reflection, their forward and reflected vectors are rotating in oposite
directions. This makes every spot along the paths of these vectors
unique with its own voltage to current ratio (impedance).

Cecil. W5DXP has already posted in some detail how the forward and
reflected values encounter the incident values and their superposition
produces a new impedance. That surely happens at the load end of a
loading coil.

If the phase between the incident and reflected waves, at the coil to
whip junction, makes a different impedance than that at the feed end of
the coil, it is likely that the coil output current will be different
from the coil input current That`s expected.
