I have Dish and have a coax cable leaving the receiver outside the house and then it comes back inside downstairs. When it comes back into the house it goes into a splitter. The splitter had one input and two outputs and the outputs said 3.5 DB. The tv's that it split to both were fuzzy and the volume was static. So switched it out to an old radio shack splitter that was laying around. One input and 2 outputs - one output is VHF and the other is UHF. The tv that is plugged into VHF is perfect but the UHF is even worse than it was before. So what kind of splitter do I need. Any ideas??????????????????
