The Pixel Technologies PRO-1A Magnetic Receiving Loop was demonstrated at the
Visalia DX Convention last month. It's about the same size as a circular or
diamond shaped coax loop. It includes a preamp mounted at the feed point. The
antenna has had several positive reviews on eHam.

Joe, W4TV, posted to the list earlier this year looking for references for the
Pixel design. The technology is based on work done by Dr. Carl E. Baum in the
mid '60s through the early '70s. A list of papers complied by Dr. Baum appears
here:

Of particular interest regarding the Mobius design are: SSN notes 7, 25 and 127
including a discussion of multi-turn Mobius loops.
A coax loop has its shield split opposite the feed point but the center
conductor is unbroken. Based upon the references above, the break opposite the
feed point in the Mobius design is in both the shield and the center conductor
with the shield of each side connected to the center conductor of the opposite
side.
If you've built your own Mobius receiving loop of tried the commercial product,
a report of your experience would be of great interest to the Top Band list.
