MOCA Network Setup

I have a fairly simple question. Can I set up my MOCA network between the Tivo Roamio and my Mini directly?



I have an OTA line running from upstairs to the Roamio. Can I setup the MOCA adapter between that line and the Mini upstairs and then use that as my established MOCA network? The MOCA adapter and Roamio will both be connected to the Router via Ethernet.
