You simply do not know that:
"In electronic circuit theory, a "ground" is usually idealized as an
infinite source or sink for charge, which can absorb an unlimited amount
of
current without changing its potential." and,

But the "ground" you are referring to in this paragraph is NOT the one you
are in the next. One is an essentially infinite sink, and the other
ignores that property entirely.

So you are arguing with yourself here.

The both paragraph are wrote by the same Author.


"The use of the term ground (or earth) is so common in electrical and
electronics applications that circuits in portable electronic devices
such
as cell phones and media players as well as circuits in vehicles may be
spoken of as having a "ground" connection without any actual connection
to
the Earth. This is usually a large conductor attached to one side of the
power supply (such as the "ground plane" on a printed circuit board)
which
serves as the common return path for current from many different
components
in the circuit." From:
http://en.wikipedia.org/wiki/Ground_(electricity)

The "large conductor, "ground plane" or "radials" are in the air or in the
space.
The air or the space are the "infinite source or sink for charge".

I assume that you know that a conductor gain/loss the charge in the
air/space.
But the conductor must be large enough.
In your "dipole" one radial is enugh but in a big station must be much more.

The same was wrote by Marconi.
