Installing the satellite dish in a home is the hardest part of the satellite system process; the connection or wiring is the easy part. Wiring for a two-LNB (low noise block converter) dish is not any more difficult than a one-LNB dish. The LNB is the portion of the dish which actually receives and decodes your satellite signal, eventually sending the signal down your coaxial cable to your television, and having two allows you to connect more than one television to your system.
Remove the LNB from the satellite dish. The LNB is held in place by a screw, which is generally located underneath the satellite arm.
Connect two RG-6 coaxial cables to the coaxial outputs on the LNB. These ports will be the only ones on the LNB, and will be cylindrical, metal ports with pin-sized holes. Insert the pins from the coaxial cables into these ports, then screw on the cables to hold them in place.
Thread the RG-6 coaxial cables through the arm of the satellite dish and out the other side. Push the LNB back onto the satellite dish, and resecure it in place with the screw.
Connect the two RG-6 coaxial cables to the two input ports on your satellite splitter. These ports will be labelled input, and will be on the same side of the splitter (the other side will have the outputs, which will number four or more).
Connect one RG-6 coaxial cable onto an output of your splitter for each television you wish to connect to your satellite system. For example, if connecting three televisions, then connect three RG-6 coaxial cables to your splitter, one per output. Run these cables to your satellite receivers.
Connect each of your satellite receivers to your satellite splitter using the RG-6 coaxial cables you just ran. Locate the satellite in port on the back of the satellite receiver; this will be identical to all the other coaxial ports used. Screw the cables onto the threaded ports.
It is STRONGLY recommended to purchase a satellite splitter directly from your satellite company. A generic one will, at best, not function well, lead to poor reception and picture and, at worst, not work at all.
