Hey All - First time Tivo Bolt user here - in fact, my unit won't be here until Monday but I wanted to make sure I understood the wiring diagram and if I need to purchase anything else. Upon reading the online manual, it looks like I need a MoCA POE Filter - so I got that ordered as well. In my home, not all locations can be served via Ethernet - so I plan to use existing Coax wiring. For my main DVR unit, it will be downstairs and connected via Ethernet to the Internet router. I plan to simply use an outdoor HD antenna for channel source - so my plan there is: Outdoor HD Antenna -> POE Filter -> 8 port MOCA Splitter - did I get that right? Initially, I will have 3 units - the DVR itself and 2 Minis. When I asked a "Geek" at Best Buy he thought a diplexer? was needed since the wall jack at the DVR unit would be both supplying signal from the antenna and communicating with the other minis - is that true? If so, I don't have one so I guess I better buy a diplexer also. Thanks for any and all input.
