Timewave - ANC-4 Noise Canceller
Back in stock soon, the popular ANC 4 Noise canceller is completely updated and
fully compliant.
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.
