Quarterwave vertical with radials

It's pretty easy to understand. Any two radials,
180 degrees apart and high enough, should theoretically
cancel each other's radiation in the far field.

=====================================
If they don't cancel-out each other in the near field then they don't
cancel-out each other in the far field either.
A pair of radials behave as a continuous dipole fed at its center via
a single wire. And it radiates.
A circular disk, diameter = 1/2 wavelength, fed at its centre
radiates.
But don't ask me what its radiation resistance is. It must be very
low.
