In the past, many amateurs did connect coax directly to a dipole.

And what they do if they have the monopole?

Connect it with coaxial transmission line, idiot.


If the monopole has only one radial it is exactly as the your dipole.
Right?


No. A monopole needs many radials, not one. if it has only one radial
the voltage at the end of the radial is the same as on the monopole,
and the whole thing becomes a dipole.


"balun definition
electronics
A transformer connected between a balanced source or load and an unbalanced
source or load. A balanced line has two conductors, with equal currents in
opposite directions. The unbalanced line has just one conductor; the current
in it returns via a common ground or earth path. "

The braid of the coax and the radial are connected. They work as the ground
(or counterpoise).

Is the voltage the same as in the live conductor (at the feed points)?
