You were totally unable to understand something as simple as:
http://en.wikipedia.org/wiki/Dipole_antenna
"The quarter wavemonopole antenna is a single element antenna fed at one
end, that behaves as a dipole antenna."
Are you able to understand something as simple as the above?
To be precise, only end fed monopoles need a counterpoise.
The radials serve as the counterpoise.
The Author in Wiki describes the "dipole" used by radio-amateurs.
Such dipole is simply "The quarter wavemonopole antenna".

No It doesn't, it describes a monopole as as dipole using the image in the
ground as the second leg!!
But what is does show is a dipole with one arm connected to the braid of a
coax!!!! Which of course you ignored!!!!!
The braid = the shield.
The braid and the arm are together the counterpoise.
Have you the same voltages on the braid and on the coax "live" wire?
If not, than you heve the monopole. But it is nothing wrong if in your
community it is call "dipole".
