here is some more on ground radials.

Among amateurs there's been a long running discussion regarding the effectiveness of a vertical with
an elevated ground system compared to one using a large number of radials either buried or lying on
the ground surface. NEC modeling has indicated that an antenna with four elevated ?/4-radials would
be as efficient as one with 60 or more ?/4 ground based radials.

Im currently working on an 80m vertcle with 3 elevated radials. The lower base of the antenna will be 35' with the radials sloping down to about 12'. It gives 8db higher gain at 5 degrees of take off angle vs a dipole at 45'
