I have 5LNB DirecTV HD Dish, Swm8, 29V Inserter with 1x4 splitter feeding Genie and 2 Clients. Can I hook up an HR21 to the unused output of the splitter using a single coax to Satellite 1 input of the HR21? Or do I have to run 2 Cables from two of the Legacy outputs of the SWM8 to make the HR21 work? Lastly will the HR21 work wired either of these two ways?
Thanks!
Thanks!
