The DiSEqC switch GX41D will enable the user to select one LNB signal between 4 different LNBs of any type.

The 4 input ports marked LNB A, B, C or D are connected to the 4 LNBs, which may be on 4 different dishes, and the output marked OUT is connected to the receiver.

The selection of the LNBs is done by choosing the appropriate Tone Burst A or B in the menu of the receiver.
