Default Galvanized or Copper Gound Rods?

sure.


" Transmitters for long and medium wave require good grounding and soil

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 ".


no they don't... those types of transmitters work just fine in


airplanes with no soil available.

In the airplanes is the "chassis ground". The large metal surface is the
charge source. The surface exchanges charges with the air.


not nearly large enough, nor necessary.

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


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

loss of electrons maybe, but due to friction with particulates in the


atmosphere. *also partly due to the fair weather electric field:http://www.missioninstruments.com/pa...ec_fields.html

In a short period of time the atmospheric conditions are similar.

I am asking for *measurement of the netto current in the track
ground-antenna.
The two measurements: before and during transmitting in the same atmospheric
conditions.

net current = 0.
