The DiSEqC switch will enable the user to select one LNB signal between 4 different LNBs of any type. This switch works well with dishes less than 50 feet from your receiver.
The 4 input ports marked LNB 1, 2, 3 or 4 are connected to the 4 LNBs, which may be on 4 different dishes, and the output marked RECEIVER is connected to the receiver.
The selection of the LNBs is done by choosing the appropriate Tone Burst 1, 2, 3, or 4 in the menu of the receiver.
