Channel Plus NF-471 Notch Filter

The Model NF-471 Notch Filter couples the incoming signal source coax cable to the input on a splitter or bi-directional DA-series amplifier. Once installed, the NF-471 filters out channels to make room for modulated channels. In addition, the NF-471 blocks the modulated signals from being broadcast back into the coax. The NF-471 is a perfect solution for modulation in the ever-increasing bandwidth taken up by Cable Television (CATV).

The Model NF-471 Notch Filter blocks incoming CATV channels 75-80 and off-air UHF TV channels 24-29, allowing 5400, 5500, and SVM series modulators to insert TV channels without interference. Please Note: To avoid interference, be sure there's an empty channel on each side of a modulated channel.
