I thinking of adding a 2nd HR20 and I've read numerous posts about the SWM and they all seem to imply that there are 4 cables coming from the antenna. I have a 5 LNB Multi-sat antenna with only 2 cables coming from it. Will the SWM work for me? If so, how do I hook it up? If not, what will I need. I have complete freedom on running cables from my current equipment cabinet to the remainder of the house. I would rather only run a single cable for the 2nd unit but I can run 2 if I have to.
