"Richard, there is no such thing as a "current drop."

This is where i came in almost a year ago. Yuri may havr posted Fig 9-22
from page 9-15 of the 1994 edition of ON4UN`s "Low-Band DXing". There
are base loading, center loading, and continuous loading examples of
short vertical antennas, and their current distributions. In every case,
the currents at the two ends of the coil are different.

The impedance of an antenna is a function of position along the antenna.
There is radiation from an antenna so not only is the impedance along an
antenna a variable, but the the transmit power level power level along
an antenna is a variable, too. These variables ensure a difference
between the current into and out of a loading coil.

Current is high where impedance is low, and current is high where power
is high.
