FYI: The user guide has a section on connecting Joey(s) and the satellite dish to the Hopper. These sections are lifts from previous manuals that direct connect to the dish and use NTSC RF "Home Video Network" to connect other TVs. The information is mostly incorrect for Hopper/Joey even though the text calls out Hoppers and Joeys!
The Joey instructions talk about connecting the "Home Video Network" to the back of the Hopper. MOCA isn't really a home VIDEO network. However, the cabling instructions from the Joey perspective are essentially correct.
There is no mention of the node. The section on connecting the dish talks about "Satellite 1" and "Satellite 2" inputs to the Hopper, and also mentions using a separator.
