How to Set a Dual LNB to 2 Satellites

A Duo LNB, also known as a "Dual LNB," is a low noise block downcoverter that contains two satellite transmission receiving modules in a single enclosure. The Duo LNB is designed to receive two separate satellite signals from the overhead satellite's transponders and transmit them to a waiting satellite receiver. The switching between the two satellites is handled by a DiSEqC switch that must be installed between the dish and the receiver. The receiver must have the technology built into it to be able to switch between the two satellite transmissions.

Instructions

  1. 1

    Loosen the screws on the side of an existing LNB attached to a lateral support pole on a single satellite dish with a hex wrench. Unscrew the coaxial cable connected to the bottom of the LNB. Remove the LNB from the lateral support pole.

  2. 2

    Screw the coaxial cable into the coax output of a DiSEqC switch. Loosen the screws on the side of the DUO LNB module with the hex wrench. Place the DUO LNB module on the end of the lateral support pole. Rotate the front of the DUL LNB module so that it is facing the dish. Tighten the screws.

  3. 3

    Screw one end of a 3-foot coaxial cable to the coax connector on the DUO LNB module. Screw the other end to the coax input on the DiSEqC switch.

  4. 4

    Unscrew the coaxial cable from the coax input on the back of the satellite receiver. Remove the cables connected to the satellite receiver. Remove the satellite receiver. Place the replacement satellite receiver that can switch the signal from the DUO LNB in the position now vacated. Connect the cables to the appropriate connections on the back of the replacement satellite receiver. Screw the coaxial cable into the coax input on the back of the receiver.

  5. 5

    Turn the receiver on from standby with its remote. Press the "Menu" button. Select the "Point Dish/Satellite" screen from the "System Setup" menu. Enter your zip code in the appropriate field to bring up a list of satellites. Select two adjoining satellites from the list provided that correspond to your location.

  6. 6

    Have a person stand by the screen with a cell phone. Go to the satellite dish and call the person on his cell phone. Release the two locking knobs on the side of the bracket holding the satellite dish in position. Raise and lower the dish until you are told that one of the two satellite meters has reached its highest point. Lock the knob controlling raising and lowering the dish. Repeat this action with a lateral movement of the dish until the second satellite's signal is also as high as possible. Lock down the other knob.
