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

This I'll try. 'Doesn't matter about spacing at the loop ends just as long
as they're not touching, 1 or 2 inches? I have a rotor that I bought at a
Radio Shack clearance for a project like this. This should help a bit with
reception as well.
I heard of someone using a hula hoop for something like this but copper
tubing I guess makes it a magnetic loop, which I hear is best for a low
noise antenna? Still use the balun?
A thousand thanks for the instructions.

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.
