The selfcapacitance of an antenna is very small. You need a couple of
electrons to have a measurable static voltage.
For this reason the earth/chassis/counterpoise is necessary.

Hello Szczepan.
A dipole aerial doesn't need a counterpoise nor does it need any
connection to earth/ground/counterpoise.
Is it your transmitter:

?
I've kept quiet during the discussion because I don't think of my radio
and aerial in terms of sub-atomic particles. For me, resonance, impendance
and SWR are more significant.
Your dipole are exactly like the two Kundt's tube. There are "resonance,
impendance and SWR". To demonstrate of the SWR the tube end must be porous.
Air molecules work like the electrons.
Have you considered taking your theories / discussions /
cutting-and-pastings about sub-atomic particles and other kindred items to
one of the physics newsgroups such as:
alt.sci.amateur
alt.sci.physics
sci.physics
I'd expect that you will find lots of people with whom you can discuss the
behaviour of sub-atomic particles.
Electrons are the subatomic particles.
Radio is the only field where "plumber analogy" is totaly inadequate.
Kindest regards,
