absolutely amazing difference in analog picture quality ! I use a two way splitter to run a line straight to my cable modem as recommend and attach the other cable to the Motorola Booster . from the booster I use three of the four hookup for signal to three tv , one of which I split again with a good two way splitter so that I could drop a line to my computer tv card . before I have horizontal line on many of the channel and a couple be almost unviewable . the line be all go now and the picture on all three analog tv and the computer be terrific ! a unintended side effect be that my cable modem throughput have also increase because it be now be route straight to the computer from the original two way splitter . I wish that I have do this year ago ! if you have analog tv with fuzzy or striped picture I highly recommend this booster !
