Look carefully at what you wrote. Couldn't you have achieved the same
results by turning the RF gain down, or shortening your existing antenna?
Noise down, signals down also? WWV gone? Hmmm. Suspicious.

I'll answer for him, ...No and No.
Receiving loops aren't about signal strength they're about improved Signal
to Noise **Ratio**.
Not hearing 20 MHz WWV at the hours he said he was listening (late eve?)
means nothing as that band folds late at night or propagation simply may not
have been favoring a path between them at that time.
Try some Google-searching for receiving loops, lots of info.

Dumb question: how do you reduce noise without reducing the strength
of the signals you want to hear? How does the antenna know which is
which?

What makes some antennas "quiet."
