An excellent question. I wish I had an excellent answer. I don't know
why the H-800 is so quiet. I just go with whatever works. Maybe someone
else can help out with greater detail.

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.

Actually, I find the H-800 to be astoundingly quiet. It's so small and
so easy to situate in a quiet spot. And once it's situated, it's as
quiet as its location.
