Actually, the parasitic systems work fine with 4 or even three dipoles,
although the beamwidth increases proportionately. Wx0B and I are arguing
offline about which system shows better F/B and gain in modeling...
One thing that hasn't been mentioned is that the tower in the center of
such an array can play a significant role, at least as reflected in the
currents that flow on it. I'm not sure what experience has been with the
effect of a tower in the center of a 4-square.
