A properly installed multi-LNB bracket at the end of your satellite dish is the only way in which you will be able to watch satellite television on more than one TV in your home. An LNB is the plastic part at the end of the long arm that extends from the satellite dish, and is actually the portion that receives your television signal and sends it on down the wire to your screen. If you have a single LNB, your dish will only communicate to a single television. However, a multi-LNB bracket has the potential to transmit to two or more TVs in a single home.
Run two RG-6 coaxial cables through the base of your dish, then down the length of the satellite dish arm so they are sticking out of the front of the dish.
Connect the two wires to your dual or multi-LNB unit. The unit will have two coaxial outputs on the front; these look like metal cylinders with screw threads on the side. Insert the pin from one of the wires into the hole, then twist until the wire is secure. Repeat with the other wire and output.
Secure the LNB onto the satellite dish arm. The portion with the satellite outputs goes into the arm, with the LNB sticking up to form a J shape. Then, in the bottom, align the screw hole on the LNB with the screw hole in the arm. Finally, install the screw to hold it in place.
Secure any loose wiring to the dish using the zip ties, then cut the plastic ends sticking out.
