MoCA with Tuning Adapter - New Splitter Needed?

Hi, all. I tried searching the forums but just need a quick answer for my situation.



I have a Roamio (basic) with a Tuning Adapter connected via ethernet to the cable modem right next to it. I will be setting up a TiVo Mini tonight in my bedroom that only has a cable outlet. I read on the forums MoCA does not play nice with tuning adapters.



Right now my cable set up is this:

Outlet->2-way splitter->Modem

___________________->Tuning Adapter->Roamio



Will I need to purchase a 3-way splitter and a second POE filter?

Outlet->3-way splitter->MoCA->Modem

___________________->TiVo

___________________->POE->Tuning Adapter



Thanks!
