It means that a dipole fed from a coax is the monopole (a quarter wave)
with
the counterpoise.


No, it doesn not mean that.

"In the case of very rocky or poorly conducting soil a counterpoise often
is
substituted for a buried network of wires. A counterpoise is a network of
wires place above the earth a slight distance and insulated from it, so
arranged to produce a very high capacity to the earth."



Radials are only required for an end fed monopole.

The number of radial required is dependant on the ground conductivity and
totally independant of power.

The number of buried radials or that above ground (counterpoise) is power
dependent.
