Art,

I have tried it (what the heck, why not?). Using a 2m x 2m 
loop, 1m above average ground: The F/B (better than 25 dB) 
and RDF (7.8 dB) are the same as a single turn loop. Gain 
is higher by 2 dB (-46 dBi). Needs three separate loads, 
one on each of the back-side vertical wires. This antenna 
would be hard to match due to high and highly reactive 
feed point impedance. I believe it is not worth the 
trouble for the small increase in gain.

Cheers,
