1. What does the Pixel Loop do better than these and other loops?
2. What does the Pixel Loop's preamp do to improve the S/N ratio???
3. And what IS its RDF?>
The Pixel loop is balanced, so it will reject locally radiated E-Field noise
providing this noise
I forget what the Pixel Loop looks like. But if it's anything like a tuned,
link-coupled circular loop in the vertical plane with a 20 dB preamp at the
loop, it will have two very deep nulls at a very low angle.
I made three like that ~35 years ago, between 1 and 4 feet in diameter,
made from
Throw bricks all you want to the end of time but you'll never change
the fact that we tested that antenna and saw its performance first
hand; The preamp was designed by Jack Smith at CliftonLabs..I'm sure
he'll enjoy reading your comments and get a good laugh.

SORRY am not getting into this PR.. PIXEL loop is a low RDF and LOW
performance receiving antenna, it is really snake oil.
I'm out of this discussion.

In tests, the Pixel magnetic loop provided at least 20 dB null off the
sides. From my experience, that is much better

A big complication is that almost everyone's circumstances are
different due to variables such as property size. A
