Is this MOCA - approved?

New Roamio, works great. Now I'm adding MOCA Minis.



Incoming cable hits a splitter. One leg goes to the ethernet router, the other to the Roamio.



Now I want to add 2 Minis via MOCA. I would like to create the MOCA network with the Roamio. BUT, the coax port on the Roamio is already occupied by the Cable TV feed.



Can I split the Cable TV cable so one leg goes to the Roamio and the second leg goes to my home's Cable infrastructure? Will this allow the Roamio to 1) receive the Cable TV feed via the coax port and also 2) back feed the MOCA signal into the splitter (via the one coax port), and therefore into my home's cable infrastructure?



Thanks.
