I got a Pixel Pro 1B antenna and it gave me 7dB more sensitivity over my dipole.
I was doing measurement with another op in my area and could clearly see his
7dB advantage on all bands which disappeared with the loop.

I refer to the "advertised capability" that it ignore E field and only pick up
magnetic h field. It was said that this reduce man made noise.
Some post said advertisement is a bit over hyped. May be, sure, it will work to
some extend?
I never saw one nor use these. Near zero rf experience

How good is magnetic loop antenna, may be with amplifier for receive
only, in REJECTING man made noise, especially at or near city area,

Loops like this have a very broad "figure of eight" pattern, with deep nulls,
so they can strongly reject sources in the nulls.
Other loops, like the VE3DO design, have a cardioid pattern.
