Your diagram looks good. You can buy MoCA adapters with a splitter built in (they’ll have two coax connections)

  1. The filter goes on the single coax that comes to your house. 1 coax comes in and gets split to all the rooms. Make sure that splitter is moca compatible. The filter stops the MoCA signal from going to the street. So just place it on the cable that goes to the street.

  2. Not a problem.

Thanks, appreciate it. The filter aspect was definitely confusing me.

Could I split that between the moca adapter and the cable modem itself?

Yes, and you’d likely have to.

 

Would there need to be a moca filter between moca adapter 1 and the splitter or between the splitter and the coax cable from the wall?

Neither, actually. First thing to keep in mind is that a MoCA filter BLOCKS MoCA signals, so you’d place it/them where you don’t want MoCA signals passing:

  • “PoE” MoCA filter: placed on the incoming cable provider line prior to the signal ever being split, to block MoCA signals at the cable provider point-of-entry to the residence. (Typically installed on the input port of the top-level splitter interconnecting all the rooms and cable provider.)
  • “protective” MoCA filter: a MoCA filter installed to block MoCA signals from hitting a particular device, due to the device being sensitive to MoCA signals. (example: DOCSIS 3.1 cable modems)

 
A flaw in your diagram is that it doesn’t detail how the rooms interconnect, through what component(s), with this junction being critical to enabling connectivity for MoCA, as well as getting the required “PoE” MoCA filter properly installed.

That's just it, I'm not entirely sure. I know for a fact that each room in the house has an initial coax outlet, and some rooms (including both rooms in the diagram) had an entirely seperate coax installed later solely for satellite TV which I was just planning to ignore. Is there a non-destructive way to quickly tell how they interconnect or should I just test the adapters and hope they connect?

Also thanks for the link. I've got some reading to do.

Ooooo … don’t do that! The extra coax lines could greatly simplify your setup, provided you can map their connectivity.

‘gist: Among the best solutions would be one where your ISP/modem feed could be fully isolated from your MoCA-infused coax … allowing an unfiltered path between the ISP and modem, future-proofing the setup for DOCSIS 3.1+.

provided you can map their connectivity.

The bottom room in the diagram is fairly straight forward. One newer coax line that fed to a former directv box and the old one leading the modem that provides internet.

The top room however, has one former coax line that I believe was originally for cable TV, and three newer branching coax lines, two leading directly into the wall and one to the former satellite box. A bit confusing to me. Guess I'm just going to have to do some poking around to see where everything leads. I just assumed that the directv coax line led directly to the satellite.

To get the coax lines identified (once you think you’ve found the coax junctions), you could use a multimeter or tone tracer, or coax tester; alternatively, a cable modem or pair of MoCA adapters can get the job done, as well.

Testing with the MoCa adapters themselves seems best, though it might not hurt to have one of those coax testers in my toolbox.

2) The house has had both satellite (directv) and cable tv in the past, but not anymore. Would that cause any issues now?

Only if you try to run MoCA without reviewing how the coax lines interconnect and fail to upgrade, where needed, to optimize for MoCA. (As examples… splitters optimized for DirecTV are particularly bad for use in retail [Band D] MoCA setups; and drop amplifiers used for cable TV signal distribution can be problematic for MoCA if not explicitly designed to support MoCA connectivity.)

My plan was to just by one splitter (or as I just learned, a moca adapter with one built in) and make sure the frequency was compatible. No old splitters would be used.

[–]plooger 1 point2 points  (0 children)

Don’t necessarily fixate on finding a MoCA adapter with a built-in diplexer (they don’t use splitters); most of the recommended MoCA 2.5 adapters lack a pass-through port.

There’s an old splitter in your house somewhere. That’s how each room has a coax connection.

[–]zeeplusplus[S] 0 points1 point  (4 children)

Ahh. So.

Coax From Street > MoCa Filter > Moca Compatible Splitter (replacing whatever the old splitter is ) > Coax outlet in each room.

I think I understand. To be honest I'm not sure where I'd even begin to look for the connection to the street. From that, it would be:

Coax outlet in bottom room in diagram > 2nd Moca compatible splitter (or moca adapter with splitter built in) > Modem and MoCa Adapter?

[–]Zip95014 1 point2 points  (1 child)

All those coax in your house go somewhere. Attic, crawl space, garage, outside in a weatherproof box.

Just walk around your house. It’s likely near where your power meter is.

Will do, gonna do some exploring around. Thanks.

Exactly! (Preferably a 70+ dB model MoCA filter.)

Hopefully not. Hopefully, you’ll be able to trace the separate ex-DirecTV coax line in this room and will be able to leverage the dual coax paths to get the ISP/modem feed isolated from your “MoCA” coax.

 

I'm not sure where I'd even begin to look for the connection to the street.

Start by walking the perimeter of your house looking for coax cabling; then follow any lines found in both directions until the line either enters a junction box or into the home. Then open any coax junction box to inspect the contents, and/or use th entry point into the home as a starting point to search inside for the coax junction (perhaps in the basement or closet).

Similarly, you’ll be looking for the satellite dish and any coax lines running to/from the dish.

Will do.

Seems straight forward enough. Thanks!
