In the giant Warsaw dipole was: "In the lower half of the mast, there

applying a DC ground at a point of minimum radiofrequency voltage,
conducting static charge to ground without diminishing the radio energy.
Static electrical charge can build up to high values, even at times of
no
thunderstorm activity, when such tall structures are insulated from
ground.


The sentence "when such tall structures are insulated from ground" is
wrong.
Should be: "when such dipole works".

try it and see... tie a wire to a kite and fly it up nice and high and
measure the dc voltage to ground. you can also draw current from it.
many years ago i built a motor that was powered by only a wire
sticking up about 20' in the clear air... very interesting free
power! but very dangerous near thunderstorm!

In clear air the electrons migrate up. Under a cloud down.
The direction of DC is weather dependent.

Of course sometimes no DC at all.

It is interesting that a wire sticking up about 20' produces DC but your
antennas no.

Transmitting antenna is like electron gun.
