MoCA, Filters, and Antenna help

Hello and thanks for helping:


I have an Antenna setup wired into my internal house cable wiring. I believe that I have done the Antenna parts well by having an amplifier, powered splitter, LTE filter, etc., but now I am looking to add MoCA to the mix. My active Coax splitter is MoCA compatible and I want to receive a wired connection in some rooms, however I am stuck on the MoCA signal filters. From my understanding, I need one filter to keep the signal from going out to the street (I have Comcast internet) and another filter to keep the signals from being broadcasted by my antenna, but the LTE filter should take care of that? Also, do I need a filter before each television to filter out potential MoCA interference? any advice on this would be appreciated!

  1. I’ve got MoCA 2.0 running, but I’m using a Tablo so my streaming TV is on my home network, not my coax cables. Also have AT&T fiber internet. The only thing that the coax is used for at my house is MoCA 2.0 signals. From my research, though, the top of the UHF TV spectrum is below 900MHz., while the bottom frequency used by MoCA 2.0 is 1125MHz. So there is a separation between the top of the UHF spectrum and the bottom of the MoCA 2.0 spectrum. So I’d suggest starting here:

    1. Replace ALL coax splitters with MoCA 2 compatible ones (up to 1675MHz.). Make sure that your amplified splitter is MoCA 2.0 compatible, and it should have a POE filter built into it. A coax amplified splitter can be MoCA 1.1 compatible, but not MoCA 2.0 compatible, be sure to check that before assuming. There happens to be a “MoCA compatible” amplified splitter at our cable “point of entry”, but it turned out to be only MoCA 1.1 compatible. The last thing that I had to do was to replace that amplified splitter with a MoCA 2 compatible one, and that also provided a POE filter for us, it was built-into the new amplified splitter. When I did the amplified splitter replacement, our MoCA 2 started working.
    2. Put in a point-of-entry MoCA filter (POE filter) if you don’t have another one already.

    You shouldn’t need any filters at your TV’s, since the MoCA 2.0 (theoretically) shouldn’t interfere with your TV frequencies.

    I’d suggest, though, that you think about getting a refurb 4-tuner Tablo to get your TV signals onto your home network rather than using the coax for that. They’re available on the Tablo web site for about $140. This also gives you the ability to use the Tablo DVR capability to record shows, but it sounds like you don’t care about that. We find the DVR quite useful :-). The Tablo works very well, and would simplify your issues.

  2. I think you might get info on how to do it from the moca manufacturer. I’m using Actiontec brand moca adapters. Let us know if you get it working, sounds like a good thing esp. when ATSC 3.0 becomes available.
