Gene,
A small, closed loop operated below resonance will have a very
low feedpoint impedance. While it will radiate virtually all the RF
it is fed, its low impedance might be tough to efficiently match to a
50-ohm unbalanced transceiver.
So, instead of making just a single turn loop, how about making a two
(or more) turn loop, instead? This would bring the natural resonant
frequency of the antenna significantly below that of a single turn loop.
If planned out correctly, you might be able to find the ideal dimensions
of a multi-turn loop that will provide self-resonance on the low end of
80-meters. Anything above that in frequency should be easy to match
as others have already mentioned.
Just a thought...
Good luck!
