I have two rooms running off of a Dish 625, the other two rooms run from a Dish 322. I want to add a new 322 I just bought to a fifth tv in another room. Just to run one TV. From my satellite there are two cables, so I tried to split that with a standard splitter and ran one single cable to my new 322. Does not work, I am completely confused by satellite installations. I am a handyman of sorts and do not want to pay an installer, I want to know how to do it myself. Can anyone help?
