You need to provide more info. How did you set it up, what receiver, etc.
Think of the cable splitter like a garden hose with a Y adapter. One hose goes into the Y adapter and 2 hoses come out each carries less water at lower pressure because the one incoming line is now split into 2 streams but you can water 2 spots at the same time.I setup my Dish HD reciever and can't tell if I set up the cable splitter right?
