Until now I have kept my comments to myself about the Pixel.

Interesting comments about the WF. I recently built one and so far it has been
a complete failure.
Care to share the details?

It took forever for our utility
I have an antenna of very similar design and performance. It is an
all aluminum lawn chair on a pole.

1. What does the Pixel Loop do better than these and other loops?

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,

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

You don't need to be in the sticks to put up one or two pennants and get a
lot of mileage out of them. I have a fairly small

them down a long time ago, because they just weren't cutting it.

Greg,
This is the main reason why I am selling
my house on the ocean shore front and
relocating to a rural area where I can
have quieter conditions. I'm taking my
radio with me everywhere I think is worth
a look and will put up a long random wire
and listen with the K3s both day and night

The file starts with some incorrect statements:
"All we need is 3 dB SNR for CW and 8 dB for SSB"
such a statement is completely meaningless if the measurement

Hi Rob,
I suppose I could just scrap out the gear and put more energy into my
music. I play acoustic instruments (no electricity needed) at some
dances and other community events along with several other musicians and
acoustic instruments. In that role we *ARE* the QRM! And

Hi Greg,
My noise is not S-9 - at least not over the entire band nor constant
around the clock. I do have some manmade noise issues. In my case a
mag-loop antenna on receive has been a lot of help. I doubt there is any
perfect antenna. But it won't cost you a lot to brew a mag loop from

Always I have wanted to permamanently run Topband, but there is just too much
QRM and RFI at BOTH my station locations.
After a late season ice-storm took out power for much of my area last weekend,
I was SHOCKED at the activity and weak signals that were now heard. Totally
amazing- but
