And why would this vertical be quieter than any other vertical? Seems
to me you can't fight physics.
Even in a quiet spot, a whip plus fet amp will be noisier than a
magnetic loop due to the nature of the noise sources.
Better read this before we start discussing that a loop can distinguish
noise sources.

I see two reasons why a loop might be quieter:
1. If there is a single noise source, the loop's null may be used to reduce
the source
2. Active whips must have a good ground at the antenna. Without it, the
coaxial shield becomes part of the antenna- both picking up noise in the
house and conducting noise from the house back to the whip.
