I'm curious as to how it compares to the JPS/Timewave unit, but that's
far too much to pay just to get the answer.

It's overhyped when it claims it's more stable ; the JPS/Timewave stays fixed
to a very fine degree over weeks. The weakness of the JPS/Timewave ANC-4 is
that the controls (particularly phase) need some kind of bandspread pot for fine
adjustment ; and that over time the pots get scratchy (albeit fixed by Deoxit
spray).

Voltage controlled phase sounds intrinsically less stable to me, but what do
I know.

I assume, but do not know, that the ANC-4 just combines a direct signal with
one that goes thru a capacitor, varying the combination with a pot, to change
phase. And another pot for gain. This is then added to the other antenna.
