Tom, with voltage feed, you only need an electrostatic ground. I used
about 10' x 10' of chicken wire for a ground sheet under mine in Hawaii.

What Andy and Skip said, plus a top corner feed causes a pattern
distortion in the broadside that narrows the beam width a bit. A
bottom element feed through a parallel network has no pattern
distortion but requires ground radials.
However you can put down a very minimal ground radial system compared
to a 1/4 wave vertical. I used only one 1/4 wave on mine and it worked
fine.
