Description 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.Features:Inserts Locally Generated Modulated Channels By Blocking Certain Channels Allows User To Create New Channels Blocks Cat-5 75-80 & Uhf 24-29 Creates Cat-5 76-79 & Uhf 25-28 Freq: 529.25mhz-559.25mhzDimension: L 5 X W 2.5 X H 1 in.Shipping Weight: 0.2 lbs
