Roger,
Even in an area with very poor ground conductivity (such as mine),
environmental losses will be reduced by elevating the lower conductor. I
would suggest 2-3 meters as a minimum. In general, loop shapes having
the lowest proximity to ground are the best, with circular being very
desirable. The late Reg Edwards, G4FGQ, wrote several programs dealing
with loops for transmit use, and RJELOOP1 would apply the best to your
situation. You can download it from:

Your actual feedpoint impedance will probably differ, but the program
allows you to play with various options in advance, perhaps saving some
money, and certainly time.
The loop is an excellent option for a lot with so many trees that a
Marconi-style antenna would have excessive environmental losses at these
frequencies.
