Yes, it can be done with a 4 x 4 22k DirecTV-style multiswitch. Hook up both linear (L) outputs on the Invacom to the two '22k off' inputs on the 4 x 4 switch, and both circular (C) outputs to the two '22k on' inputs on the switch. On the 4 x 4, there are four outputs. One will go to the 'LNB' port on the motor, then connect the motor 'Receiver' port to the primary receiver (the one that will control the dish). The other three outputs from the multiswitch can go to additional receivers directly. On all receivers, set circular satellites (DBS satellites) to '22k on' and the linear satellites to '22k off'.
