Nope, you just don't understand what is meant.

Each transmitter needs " an infinite source or sink for charge".

Nope.

The above you know.

But some of you do not know that where the voltage is there is the field
electron emission. So the sink is necessary.

Meaningless babble.

It must not be infinite. "a large conductor" absorb the electrons from the
air. So its size must be adequate to the emission.

More meaningless babble.

Antennas do not have a chassis.

In the days of wired electronics, the chassis was the metal box the equipment
was built in and used as a common return, i.e. what is called ground but
has no relationship to the Earth. By convention it was mearly the common
connection point for the most negative voltage.

In todays world of circuit boards, there is often no chassis.

Most portable equipment these days is a circuit board in a plastic box.

No chassis.

No ground, as in to the Earth, connection.
