I would like to hear how your 80M Delta loop performs for you.
I had one strung form my tower at 80 feet fed as Dennis said 1/4 wave from the 
apex.  I could work any DX that I could hear but it picked up 
much more noise (local electrical) than my inverted L I had up previously.   I 
was feeding with 450 ohm ladder line.  I am thinking of stringing it 
up again and this time feed with coax and see if it is better.  I suspect the 
ladder line was the culprit, not sure.
