And we would need the specific dish model and type of LNBs, and the model of any switch in the system. Which satellites do you have dishes pointed at?Ken Green said:In order to determine what you may need, it would be necessary to know what you already have.
Ultimately, a DPP44 will probably be needed. They aren't cheap, and neither will be purchasing the additional receiver (you're already at your lease limit with Dish). But a DPP44 would allow for the 3rd and 4th line, so that you could move your 3rd receiver between those two connections as you desire. Running the 4th line where no receiver exists is going to be custom work payable to the installer.That being said, if you already have, or added a DPP44 switch, it is capable of running up to 4 622/722's, requiring just one feed from the switch to each receiver.
