Default Current through coils

More likely necessary. It is dead simple.

You have a whip with a loading coil somewhere in the circuit under it.
The r-f energy is reflected by the open circuit at the tip of the
antenna. It must return toward the sender. There is no place else to go.

Anything feeding the antenna is in the path. Volts and amps at any and
all points along the way are acted upon by the incident and the
peflected waves. Straight wire or coil, the effect is the same as there
is a periodic variation in volts and amps due to the combination of the
effects of volts and amps from both directions.

Should the current at both terminals of a loading coil happen to be the
same, it would likely be a rare coincidence.
