How does an ANC-4 work, _as to the phase shift_? Is the one input just
split
and one leg run thru a capacitor and resistor to ground, and you select
some linear combination of the two inputs?
That selection then being added to the reference antenna's.
I'm interested in building an 8-input ANC-4, in effect.
It works the same way as the one on the Hallicrafters (or was it Hammerlund)
receiver back in the 1940/50's. Odd that the rice boxes don't come with one
already built-in---they are not complicated circuits.
Vic Misek has a couple of circuits in his Beverage Antenna Handbook. He
uses them to null steer parallel wires or two-wire Beverage antennas
