Default Wellbrook loop vs Pixel Technology's RF Pro-1A

For the diminishing number of you who are still interested, here's a
link to a review comparing one of the Wellbrook loops to Pixel
Technology's RF Pro-1A magnetic loop antenna:

I still prefer a tuned, passive loop to the amplified, broadband
variety.

Thanks for the comparison link,. I've been waiting for this and maybe a few
more antenna comparisons as well.
There was one advertised recently and I remember it was a piece of coax that
you could lay around the apartment and it supposedly gave you remarkable
results for around $75 plus shipping CONUS. I've done a search of cable
antennas but cannot find it now. Perhaps you or someone can remember this.
Anyway thanks for your time.

Do you or some of the others have any input on this antenna? Seems a bit
too good to be true but great if it works.

Cheaper just to roll your own transformer and hook up a wire to it.

I have a 9::1 balun.
This coax cable they describe, would any other cable say RG8/RG6 do the same
job? Live close to heavy industry and the noise at times just blankets the
area. NEED a quiet antenna. Thanks for the help!

If you need a "quiet" antenna, go for a loop. I had a home brew loop that
worked well, though I had to use a preselector with it. It was almost like a
miracle. Because it was a shielded loop, there was almost 50dB less noise,
and good directionality.

I made the thing from 5/8 copper tubing and some 8 AWG electrical cable. I
just put the cable inside the copper tubing, then connected the three wires
in series, soldered one end to the tubing and connected the other end to the
center of a piece of RG-8 (RG-8X is just as good and much easier to handle)
and clamped the ground braid to same place as the wire attached to the
tubing. This was a 4' loop, so worked as well at MW as SW. Unfortunately, I
don't have it anymore because the harsh climate destroyed it after only a
couple years.

Justis,

Try a single turn Horizontal [Flat] Loop Antenna using
a Coax Cable RG6 'Quad-Shield' [72 Ohm] and a 4:1
Matching Transformer. -versus- a Long Wire Antenna

Use a single insulated multi-strand wire for the Antenna
Element; or use 300 Ohm [TV] Twin Lead run as a
parallel [2] wire single turn loop.

Any 3~4~or~more points to mount the Loop will do
Does not have to be a perfect circle or square.
Does not have to be perfectly flat generally horazontal
will do.

The PAR EF-SWL is actually a random wire with a very well made
matching transformer. It is likely to be a very good antenna of its
type. The antenna "radiator" is not a coax, but a plain insulated
flex-weave wire, designed ideally to be suspended at some height above
the ground. If installed properly, it should provide a good signal to
noise ratio.

The Wellbrooks are somewhat more elaborate designs, amplified magnetic
loops. They work very well in RF-noisy places, but you pay for
compactness and performance.
