  • What's Included
  • If you want to use a modulator to view surveillance footage on a specific UHF or CATV channel from any television in your home, you'll need access to one or more empty channels. If you can't find an empty channel, you can block CATV channels 75-80 and off-air UHF TV channels 24-29, thus allowing modulators to insert a channel without interference. With this notch filter in place, you can create two modulated channels (76 & 78) on CATV and two channels (25 & 27) on UHF.



    How it Works
    Once installed on the incoming coax line, this device filters out channels to make room for modulated channels. In addition, the notch filter blocks the modulated signals from being broadcast back into the coax. Notch filters are also available that block CATV channels 64-70 and UHF 14-19 for 3 modulated channels and CATV channels 70-74 and UHF channels 19-23 for 2 modulated channels.

    Works perfectly. Let me add 2 channels with no interference with other channels and allowed a nice clean picture.

    High quality, but too agressive on the low end of the notch. decreased channel 74 signal by 50%. 73 by 10%. Work well for CATV insertion.

    Works as expected: completely blocked the specified channels without affecting the non-blocked channels at all!

    works very good, however, it block out channels that we would normally watch.

    It works great. Digital cable channels caused extreme snow on my inserted channels 77 and 79. After inserting the filter, the snow was gone.

    Does exactly what it's supposed to do. Enables my modulated signals to be completely clean from interference.

    The notch filter has rather "broad shoulders" and affects channels down to 72 and up to 83--otherwise it works fine.
