So, I'm trying to prepare as much as possible ahead of time for my Hopper installation. I'm only planning on getting just the Hopper alone and no Joeys. I've currently got a 922 with one coax (I think RG6) cable coming from a 1000.4 dish that splits in two right before connecting to the 922. I have an old Sirius antenna with a single coax (also RG6) that I'm no longer using that is right next to the dish. So, if I disconnect the Sirius coax line and have it available for the installer to connect it to the dish, that would work as a second line. Those two lines from the dish would then connect to a Single Node and a single coax line would come from that Node to the Hopper. Is all of that correct?
