Your "electron gas" is a cloud of photons emitted
by electrons. Those photons are infinitely
"compressible".

The first place where the doubled amplitude
(amplitude means voltage or electron density) appear is end of the radials.
The next is halve wave apart from the end. Such places radiate strong
electric waves. They are the source of radiation."

Again, it is impossible for the voltage maximums and
current maximums to both radiate since such would
double the radiated frequency which it doesn't. We
usually transmit and receive on the same frequency.

You must decide whether the peak radiation comes
from the current maximum or the voltage maximum since
they do not occur at the same time. Until you make
that choice, rational discussion is not possible.
