Is it possible to measure the netto current in the track ground-antenna?


sure.



The field emisssion probably works in an antenna: "Field emission can
happen

from solid and liquid surfaces, or individual atoms into vacuum or open
air,"


field emission is not likely at amateur power levels.


" Transmitters for long and medium wave require good grounding and soil of
high electrical conductivity. Locations at the sea or in river valleys are
ideal, but the flood danger must be considered. Transmitters for UHF are
best on high mountains to improve the range ".

So I look he http://en.wikipedia.org/wiki/Warsaw_radio_mast

"This technique works by 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."

Would be interesting to know the value of the DC current.

Do you agree that it is the field emission (loss of electrons)?
