I currently have an H2K and one Joey. Looking to upgrade to the Super Joey. Currently there are two coax wires coming through my wall. Looking at the wiring diagram, there will still be just two wires coming through the wall. All the changes will be outside, consisting of adding the integrator, with one coax from the dish to it, and then the jumper from the single node to the integrator. Is this correct? I have no problems with the installer coming inside, I just don't need more holes drilled in my walls!
