Light (and radio waves) are the oscillatory flow of electrons (L. Lorenz

Glass, ice and water are insulators.
As you probably know the wires insulated with the water do not work.

Yes they do actually.

A wire coated with the melting ice do not work.

You can also put salt water in an insulating glass tube and use it as an
antenna.

Is it used by U-boots?

It is the wave lenght dependent.

What is?

In the salt water works only the ULF.

You did not answer the question. I will restate it.

How can a wire that is completely insulated with respect to electrons
radiate an RF signal?

No insulators to make a wire that is completely insulated with respect to
electrons. It is the material, thickness and frequency dependent.


An additional question.

Since radio waves, according to you, are made up of electrons, how do
radios receive and transmit inside building which are made of insulating
and nonconducting glass and concrete?

Light (and radio waves) are made up of electrons, according to Faraday, L.
Lorentz, Tesla and Dirac.
The conductance is the frequency dependent.
The light travel in the glass fibre but do not travel in a copper wire.
