You can use one radial - as minigrass showed in the pictures above. It will skew the radiation pattern (gets 'lop sided') if you want to use less than four. But it will work.

Please note that the radial is at a downward slope from the center radiator. Lowering the radial(s) from being level can be used to tune the SWR for optimal reflection. Usually, a 30 to 45 degree downward slope of the radial(s) is where you will find the best SWR.
