And I forgot to include that there is no field emission, so no charge
could possibly build up.

Emission is the result of voltage.

If the power is ON the emissin take place.

Incorrect.

"(II) Field emission: In this method, a strong electric field (i.e. a high
positive voltage) is applied at the metal surface which pulls the free
electrons out of the metal because of the attraction of positive field. The
strong the electric field, the greater is the electron emission. "

You are incorrect.

that quote is correct... unfortunately the voltages created by most
radio transmitters aren't high enough to overcome the metal work
function so no field emission takes place from antennas. and even if
it did it wouldn't go anywhere because radio waves are symmetric.
