Earl K6SE described here a diamond shaped terminated loop (one of the
Flag/Pennant family) which is nearly the exact size of the conventional
"magnetic"
loops shown here. I constructed it and also have a mag loop -- go with the K6SE
as 1) the mag loops are clearly inferior as they are very difficult to build
properly AND 2) have no high angle discrimination - while the K6SE loop offers
cardiodal pattern, a deep null, is easily rotable and has good low angle
coverage. It could be use to null QRN or manmade noise or favor a particular
direction..
I have photos of mine if anyone is interested -- took less than 30 minutes to
construction once you have the pieces.

Here's one URL (of hundreds, I'm sure) I found with Yahoo! showing
construction of a shielded coax loop RX-only antenna for both 160 and 80M:
