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.
