Bill,

Sounds great !  hihihi  A lot cheaper than a Pixel too !

Until now I have kept my comments to myself about the Pixel.
I had a Pixel for a short time and sold it.
At the time I had electrical hash from one direction due to loose hardware on a power pole. It took forever for our utility company to fix it. I have a Waller Flag for receive on 160 and it was very effective at nulling out the power pole noise. I read all the rave reviews on the Pixel and thought it would outperform the Flag for nulling out the noise and was also curious how it compared to the flag on picking up 160 DX signals. The Pixel did provide a nice null from the power pole noise but not nearly as deep of a null as the Waller Flag. On discriminating 160 DX from the band noise level it was very poor indeed. The Waller Flag way out performed the Pixel. I could hear DX stations with the flag and could not hear them at all on the pixel when receiving stations close to the noise level. The Pixel would be suited for someone in an apartment or with a small lot and doesn't have the room for a larger receiving antenna like the Waller Flag. It is a compromise receiving antenna but we have
to work with what we have as far as room for antennas.

73,

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

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 "filtering" than what
would be had with a horizontal loop.   Of course it isn't all in the
antenna itself--a great deal of the success comes from the special preamp
designed for use with the antenna.
