You would need to add a switch to the system. The 1000.2 can only run 3 receivers. By adding a single switch you could run 1 more receiver. It would take 2 switches to add more.
To go to 4 receivers you need to connect a DPP44 switch to all three satellites (D100.2 outputs 1, 2, and 3 to inputs 1, 2, and 3 of the switch respectively) and put a power inserter on output #1 of the switch then run the 4 outputs to your 4 receivers. For more than 4 receivers, you can cascade another DPP44 off the first one.
