"The current which flows on the outer surface of the shield is called common
mode current. In other words, it is the unbalanced current not returned
within the coaxial cable.
This leads to a very important question. If the current isn't returned in
the cable, where does it go? The answer is, it radiates! In fact, the amount
of radiation from the coax cable is directly proportional to the common-mode
current on that cable." From: http://www.k0bg.com/common.html

"In fact, the amount of radiation from the coax cable is directly

The currents consists of electrons.

Does it means that the electrons jump off from the end of the radiator?

In Faraday time no such meters but Faraday had know that electrons (nuclei)
jump off from the end of the open circuit.

Also L. Lorenz known that the light is the oscillatory flow of electrons.

No, it does not mean that.

There are no jumping electrons involved in radiation and you are an ineducable
idiot.

No, Faraday did NOT know that as it doesn't happen that way and you are
an ineducable idiot.

I looked at my antenna the other day while I was talking. I saw some
jumping off. Szczepan has been right all along. Or maybe it was bird do
do I saw falling. Anyway, something was coming down from my antenna.

Hello Michael.

The do do has been extinct for centuries. Have I misunderstood your email?

73, Ian.

Me too but I know what it is; the insulation from the cheap Home Depot house
wire I used to make the antenna.

The damn insulation is hard to strip off when it is new but falls off all
by itself after a couple of years in the sun.

Maybe the insulation is falling off because of all the electrons that
have tried to jump off the wire when you were transmitting, and became
trapped inside the insulation?

Sorry, electrons cannot move fast enough to support RF current which cannot flow inside a wire. The RF EM wave flow is supported by photons moving at the speed of light in a cloud surrounding the wire.

Electrons are known to "jump off from the end of the radiator". It's called corona and it is visible at night. Fortunately, it happens only under special conditions because that energy is not coherently radiated, i.e. not useful for anything except melting the ends of an antenna.

In Faraday time no such meters but Faraday had know that electrons (nuclei)

Yes, arcing is a common occurrence. Unfortunately, nowadays it is useless (and illegal) for RF communications. BTW, nuclei is plural for nucleus and there are no electrons in the nucleus.

Your antennas are the diwire.
From the radiating wire the electrons jump off and penetrate into the
counterpoise wire.
It would be interesting to know if is any difference in behavior of the
different wires.

From experience we all know that there is no difference between te
behaviour of insulated or blank wires when used as an antenna. We use
what is convenient.
This sort of contradicts your claim that electrons jump off the wire,
as this would not work as well with an insulated wire as with a blank
wire.

Hello Szczepan.
"Diwire"? What's that?
"From the radiating wire the electrons jump off and penetrate into the

Sounds like a rather short circuit. Not much chance of a QSO.
