Counterpoise is exactly like underground "ground". But if the soil is dry
sand or the rock there no free electrons. It is better to place the
conductors in the air.

But they are not connected to a source of free electrons, so if those
would be required they would be depleted pretty quickly.

Air is not perfect insulator. Counterpoise has a big surface.


Where the voltage is there must be the electron emission.

Experiments with the photoelectric effect shown that no current below
10V.
But it apply to the flat cathode.
If the cathode is a wire the voltage is lower.

And what is with your antenna in sunny day?

Even if there are a couple of electrons that jump off the antenna,
it is not going to cause a measurable effect. You need more than a
couple of electrons to have a measurable current, and it is not going
to happen at those voltages and daylight conditions.

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.

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.

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.

Kindest regards, Ian.

Is it your transmitter:

?

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.

Electrons are the subatomic particles.
Radio is the only field where "plumber analogy" is totaly inadequate.

Definitely not. That's a full wave aerial. It's an FM transmitter. I use SSB
and CW.

The ends of my aerials are not porous.
According to Wikipedia, Kundt's tubes are used to measure the speed of sound
in a gas or solid rod.

You are so stupid you can't even understand a picture, you stupid idiot.

No such thing happens, you stupid, stupid person.
