A satellite dish receiver comes designed to send a satellite signal to one or two televisions, depending on the type of satellite receiver you have. If you want more than two televisions to have access to satellite programming, you can split the satellite signal using a splitter. The splitter allows you to plug your satellite cable into one end, and it splits the signal among multiple cables that you can plug into the other end of the splitter.
Split the Signal
The cable that runs into your house from your satellite dish will plug into the "Satellite In" connector on the back of your satellite receiver. That cable carries the satellite signal from the satellite dish to your receiver. Plug a cable into the "Satellite Out" connector to carry that satellite signal to your television set. Before you reach your TV, though, you can split the signal so you can run satellite cables to every room in the house.
Connect a splitter on the end of your cable by screwing the connector onto the barrel. Splitters can split the signal two, four or six different ways, so you can plug as many cables in the other wide of your splitter as there are connectors. Run each one of those cables to the room where you want satellite programming, and plug each cable into the "Television In" input to send the satellite signal to each television.
Locate Your Supplies
You can buy both the cabling that you need and the splitter at your local electronics retailer or online through electronic websites. Buy long runs of cable so you can run the signal from the satellite dish or splitter into your satellite receiver. Count the number of televisions you want to run your satellite signal to before you head to the store so you know how large of a splitter you need.
Manage Your Cables
Long cable runs can cause cluttered spaces and, if someone accidentally grabs the cable when they're up in the attic, it can force you to head back up to the satellite dish and start the project over. Instead, manage your cables to keep the area clean and protect your cabling. Use wire ties and tacks to either tie wires together or tack them to your studs. Only do this for stationary wires, however. If you need to pull slack on a cable later on, you cannot do that if your wires are tied together or tacked down.
