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

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.
