The Model NF-470 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-470 filters out channels to make room for modulated channels. In addition, the NF-470 blocks the modulated signals from being broadcast back into the coax. The NF-470 is a perfect solution for modulation in the ever-increasing bandwidth taken up by Cable Television (CATV).
The Model NF-470 Notch Filter blocks incoming CATV channels 70-74 and off-air UHF TV channels 19-23, allowing 5400, 5500, and SVM series modulators to insert TV channels without interference.
NOTE: To avoid interference, be sure there's an empty channel on each side of a modulated channel.
