The Model NF-469 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-469 filters out channels to make room for modulated channels. In addition, the NF-469 blocks the modulated signals from being broadcast back into the coax. The NF-469 is a perfect solution for modulation in the ever-increasing bandwidth taken up by Cable Television.
The Model NF-469 Notch Filter blocks incoming cable TV channels 64-70 and off-air UHF TV channels 14-19, allowing 5400, 5500, and SVM series modulators to insert a channel without interference. With the Model NF-469 Notch Filter you can create three modulated channels (65,67,69) on CATV and three channels (14,16,18) on UHF.channels
NF-470: Notch Filter
Removes CATV channels 70-74 and UHF channels 19-23, allowing insertion of locally-generated modulated channels, passes all other channels
NF-471: Notch Filter
Removes CATV channels 75-80 and UHF channels 24-29, allowing insertion of locally-generated modulated channels, passes all other channels
