Hopefully, you now have it clear that you can use your existing R-16 DVR's utilizing one cable run to each with only the addition of the SWM hardware. You will also need 2 75 ohm terminators to cap the 2 unused inputs on the SWM8 switch. You run 2 coax from the dual LNB on your antenna to the SWM8 and cap the other 2 inputs. You will then either run 2 coax from the SMW8's 2 outputs, one to each receiver (no SWM splitter required) or run one cable inside the coach to the splitter and one cable to each receiver from there.
