Overview

  • Block a set of CATV and UHF channels to assign them to surveillance cameras
  • Create up to two modulated channels to broadcast without interference
  • Modulator sold separately

Essential Info

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 70-74 and off-air UHF TV channels 19-23, thus allowing modulators to insert a channel without interference. With this notch filter in place, you can create two modulated channels (71 & 73) on CATV and two channels (20 & 22) on UHF.

What's Included

  • Notch filter

    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 75-80 and UHF channels 24-29 for 2 modulated channels.

    BRIAN -- delaware, OH   3/15/2012
    worked perfect for injecting my security feeds
    STEPHEN -- peyton, CO   10/5/2009
    In addition to blocking channels 70-74 as you would expect, it also screws up 68, 69, 75, and 76. We wasted money by buying this.
    PAUL -- kirkland, WA   1/10/2009
    This works as advertised - bit bigger than you may expect, but it fits in behind the coax quickpanel
    Greg -- Boston   6/29/2008
    works great if for 'raw' no box applications on the cable run with direct hookups to a TV. Blocks the range as expected. you may be surprised tho at what channels you lose if you have a cable box hooked up elsewhere on your system as cable box channel 251 example only may reside in the blocked bandwidth on the wire 70-74and be lost too. Trial required to know for sure. Do not expect to be able to view a modulated signal via your cable box.
    MICHAEL -- oakland, KY   5/17/2008
    it works as promised
    LEE -- orlando, FL   4/26/2008
    Works as described. Good product.Thanks!
    Jang -- Toronto   2/25/2008
    It works fine but also blocks HD channels or Rogers cables Canada
    ANDREW -- bethlehem, CT   11/23/2007
    Pretty much blocks channel 75 also which makes it not watchable. Does the job.
    ANTHONY -- kansas city, MO   8/13/2007
    works very good, however, it block out channels that we would normally watch.
    DALE -- grand blanc, MI   7/26/2007
    Blocked channels as expected!
    PHILIP -- seattle, WA   7/18/2007
    Works like a champ.
    DONALD -- asheville, NC   6/21/2007
    The filter works great at blocking out my existing cable channels 70 to 74, so that I was able to add my own Channel 73 and 75.
    JANICE -- kalamazoo, MI   3/15/2007

    CHRIS -- edgewater, MD   2/8/2007
