The key factor is the oscillating, nonsymetrical flow of electrons.

In the oryginal Hertz dipole electrons jumps accros the big gap with the
high frequency. Calculate the velocity.
The key factor is the generation, by the oscillating electrons, of RF
photons/fields/waves (traveling at the speed of light) .
Electrons do not need go-between. Electric waves are in substances and in
the plasma (rare plasma in space).
