Connecting one satellite dish, such as a DirecTV or Dish Network dish, to two receivers requires the use of a dual or multiple LNB feed horn. You can check the type of LNB to determine if you are able to connect a second receiver to the dish. A professional installer is able to easily set up a new LNB, if one is needed. However, to save money on the cost of a service call you can check the LNB yourself.
Locate the screws used to secure the LNB to the end of the satellite dish.
Hold the nut, on the bottom of a screw, with the pliers. Remove the screw by turning it to the left with the Phillips-head screwdriver. Repeat this step for the other screw.
Pull the LNB away from the arm of the satellite dish.
Examine the back of the LNB for additional coaxial outputs. If the LNB has two or more outputs, you have dual or multiple LNB feed horn.
Remove the back cover of the satellite dish with the Phillips-head screwdriver.
Insert the end of a coaxial cable into the back of the dish and push it through until it comes out the arm.
Screw, by hand, the connector to an output on the LNB. Tighten the connector fully by using the pliers.
Set the LNB back into the arm on the dish. Insert the screws and secure them with the screwdriver and the pliers.
Set the back cover in place and secure it to the dish.
Run the coaxial cable from the dish to the inside your house. Drill a hole in the wall with a power drill, if necessary, to run the cable.
Run the cable, from the inside of your house, to the location of the second receiver.
Connect the coaxial cable to the "Antenna In" port on the back of the receiver.
The acronym LNB stands for Low-Noise Block converter.
Call your satellite company to activate the second receiver.
