Oddball MoCA configuration advice?

Hi guys, I’m looking to set up a MoCA system in a friend’s house, but there’s a catch that I can’t find any pointers on - the internet connection uses the only viable F connector for the router-side MoCA adapter. I have no idea if it’s okay to use a splitter here, running one side to the cable modem and the other to the MoCA box, or if it’s even viable to run MoCA through a cable with a live internet connection. Thoughts? Also, is there a specific type of splitter I’d have to use, if so? It’s been a while since I’ve worked with this stuff, but I remember some types of splitters being okay to use, and some not.

It’s ill advised. They can most certainly operate at frequencies that would stop either from working correctly. You probably won’t be able to find splitter filters so just any ol splitter is the way to go. Try it and see is all I can say.

Some splitters work, usually those that have cutoff frequencies above what MoCA uses. They’re listed on Wikipedia depending on the standard.
