OK so I don't know what type of Slimeline dish that I have but it has four cables coming from it and only one is in use. The satellite service guy set up the HD DVR in my living room but I have an extra receiver (not HD or DVR) for the bedroom which was not hooked up. The cable that runs from the dish to my home is only connect to one port at the dish but contains two cables and what I assume is a ground wire. I tried connecting the second cable to another port on the dish and then hooking up my receiver but I get no signal. Do I need to purchase a whole new cable to run from the dish to my home or do I need one of those mutliswitches? I am at a loss.
