First and Finest in Noise Reduction. I will ship in 5 days after I receive payment. No returns or refunds due to parts swappers or poor knowledge, understanding, or incompatibility. The ANC-4 is an rf device that eliminates or reduces power line noise, BPL noise, computer noise, TV-generated interference, and other types of electrical noise. The ANC-4 unit connects right to the antenna connector of the receiver or transceiver to cancel locally generated noise before it gets into the receiver and affects the receiver AGC circuits. Reception of signals well below the noise level of the local interference is possible. To cancel locally generated interference, the ANC-4 detects the interfering signal and adjusts its phase and magnitude so that it matches the offending interference at the receiver input, but is 180 degrees out of phase, effectively cancelling the interference. This scheme is particularly effective at reducing local power line noise or other locally generated noise types.Front panel controls allow adjustment of both the phase and magnitude of the local interference, providing extremely deep cancellation of the offending interference.The ANC-4 connects between the main station antenna and the receiver antenna connector. A second antenna connects to the ANC-4 to act as a noise pickup antenna. A short wire antenna or a short collapsible whip is generally satisfactory for eliminating noises generated around the operating position or in the house, but an external antenna usually works better to eliminate noises generated outside the home. Any noise antenna that works, including combinations of horizontal and vertically polarized antennas, is satisfactory. The ANC-4 operates as an active antenna by using the noise antenna and the NOISE GAIN control to amplify the antenna output. The unit can also be used as a diversity combiner to peak weak signals or null interfering signals. Maximum Transmit RF Power Through Unit: 250 W PEP Please see all attached photos.... Sold as is....
