wow ! this booster have change my tv watch experience . my picture quality be very poor prior to install the booster . I have line on all my local channel and the picture quality be weak . the cable company could not come up with any solution and provide some bad reason for the problem . I go online and do some research and find this signal booster . be my picture quality 100 % perfect ... no , but the improvement be huge and the money spend for a higher quality splitter be well worth it . the only complaint be that you have to purchase a coaxial cord\/connector to connect the booster to the power source ... I do not realize this at the time of purchase so I have to make a extra trip to the store .
