Description 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.Features:Inserts Locally Generated Modulated Channels By Blocking Certain Channels Allows User To Create New Channels Blocks Cat-5 70-74 & Uhf 19-23 Creates Cat-5 71-73 & Uhf 20-22 Freq: 499.25mhz-523.25mhzDimension: L 5 X W 2.75 X H 1 in.Shipping Weight: 0.21 lbs
