Timewave ANC-4

Antenna Noise Canceler and Diversity Combiner

Effective with any HF/6M transceiver (up to 250W) or receiver from 500 kHz to 80 MHz. Reduces or eliminates power line, computer and TV noise by canceling it before it affects the receiver's AGC. Connects between your antenna and radio with a second antenna acting as a noise pickup antenna. Controls adjust signal phase and magnitude from the two antennas to effect noise cancellation. The ANC-4 operates as an active antenna by using the noise antenna and the NOISE GAIN control to amplify the antenna output. And it can also be used as a diversity combiner enhance weak signals or null interfering signals. 11-16V DC @ 300 mA. Dim: 6"w x 1.7"h x 4.3"d; 2 lbs.
