Sounds like you are using a stream of salt water as a radiator! Is the
pump Bismuth coated to prevent corrosion?


In each radiator is a stream of electrons. The oscillating pump is in the
transmitter. But where is the tank with the electrons?

It is in the buried or elevated radials. R. Roy wrote: "If the earth was a
perfect conductor then those currents could travel
through the earth without loss, and a single, short ground rod would
serve as an electrical reference point for the r-f current flowing in
the antenna system. The sum of those r-f currents flowing in the
earth around the monopole, and collected by that ground rod will be
equal to the base current in the 1/4-wave, series-fed monopole"

The soil is different in each place. The air is similar. So the elevated
radials are universal. They catch the electrons from the air.
