I think we need to avoid Szczepan's black and white (and usually
completely wrong) way of thinking about things. We need to consider
"When does a monopole become a dipole" (or vice versa).

With no actually ground connection, you could have a nominal monopole
with (say) only one radial (eg an extremely badly radiating quarterwave
radial running horizontally at ground level, and a quarterwave radiating
element going vertically (or semi-vertically) upwards. If you then raise
the radial so that it starts to radiate better - or if you raise the
whole antenna system away from the ground - it will then increasingly
become a dipole.

It is always a dipole no matter where it is.

The type of antenna is determined by it's geometry, not it's location
or it's transmission line.

It is the radiation pattern of the antenna that is effected by it's
location.
