If you can see your dish, is there 1 or 4 wires running from it into the house? If they installed a SWM LNB then you are out of luck. However, if they installed a separate switch, then that device will have 2 "legacy" ports that will work with your SIR-4040.
Current Setup: 2 Roamio Pros, 5 Minis on FiOS (all with lifetime)
