Isn't a quarter wave vertical with a counterpoise just a bent dipole?
Remember the CrankIR?

It does not need a radial system of wires to avoid loss. It just

NO! Radials do NOT provide a path to earth, which is a big resistor.
They are a REPLACEMENT for earth as return for antenna current! A good
radial system SHIELDS the antenna's EM field from lossy earth in the
very near field.
In arrays like a 4-square, a good radial system serves to improve the
balance between elements, with the primary effect of deepening the
nulls, secondarily improving the forward gain.
