Linear NF-471 Notch Filter Blocks CATV Channels 75 - 80 and UHF 24 - 29 Creates CATV 76 - 79 NF471 1 Pack In-Line Notch Filter Coupler Barrel Adapter
Linear 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.
