    Filters 72-83. I don't watch those channels anyway, so doesn't matter to me, but maybe to someone else it will.
    GREGG -- tupelo, MS   6/7/2009
    Does the job, allowing a clear signal to be received from an in-house modulator.
    ALBERT -- clinton, NY   1/5/2009
    worked as advertised
    AL -- edmonton, AB   10/10/2008
    This product works exactly as described. I had a problem with the first one I purchased but it was promply replaced. Customer service is A1+++
    Greg -- Boston   7/30/2008
    it will work with digital cable on a direct hookup no box input. keep in mind the frequencies channels blocked on the direct hookup may not correspond with the channels 64-70 shown on the cable box. If you have an application where you are using a direct wire input, this will work.
    Phil -- denver, Colorado   5/28/2008
    Don''''''''''''''''t buy this if you have a digital cable box. It does not block those channels. I called Leviton''''''''''''''''s tech support and they said they were aware it didn''''''''''''''''t work w/ cable boxes.
    JAMES -- mukwonago, WI   3/28/2008
    I am extremely satisfied with the product and especially the response time.
    Dan H -- carlsbad, CA   11/10/2007
    Works great for me. I have digital cable, blocks out the 75-80 range as advertised. I run our modulated internal signal on channel 77 and all is well. Great product, great site, fast shipping.
    AL -- edmonton, AB   9/14/2007
    Straight forward installation. Worked perfectly in Canada with digital cable box service. Thanks.
    MARKO -- tarzana, CA   4/18/2007
    Product arrived quickly with free shipping which is what sold me on ordering the product. The filter works just as described. Thank you.
    MATTHEW -- new york, NY   4/5/2007
    don't bother using this with a digtal cable system
    GERALD -- hampton, VA   3/29/2007
    Works great !! Wish there were more ranges available.
    ERNEST -- satellite beach, FL   2/22/2006
    Filters out channel 73 and 74 also which I did not want filtered.
