So we know that the electrons are liberated from the end of antenna.
But where the electrons come from?
From: "the earth"?

So I suppose we should develop some antennas that have a current maximum
at the end of the antenna?

Antennas liberated the EM waves and the electrons.
More electrons is liberated more electrons is flowing in the antenna.

EM travel in space. Electrons fall down on the earth.
For this reason the earth is necessary.
Do you agree?
