If the ends of a 1/2WL dipole are terminated to
ground by ~1000 ohm resistors, the antenna current
is relatively constant. :-)

Cecil:

In one of the configurations of a 1/2 wave, the bottom helix and length
of the straight length of radiator ends up right at ~8.1 ft. The upper
loading coil and top-hat/upper-radiator ends up being ~8.1 ft. This,
most likely, helps to force the current into that upper loading coil.
As, Robert Vincent, has mentioned something about "storing" the rf
energy in the bottom helix with the effect of it having a relationship
to "driving" the upper portion of the antenna.

I don't know, he has offered me a CD with complete data on the antenna,
I am arranging a anonymous address to have the CD shipped to now ...
