    Reports from others on TCF indicate that a 4-tuner Roamio's wireless isn't capable of reliably supporting even a single Mini.

    Just add the MoCA adapter, connecting the Roamio OTA to the MoCA adapter's "TV/STB Out" port and you're good-to-go. (Assuming the Ethernet connections as previously stated.)

    More options listed here.

    Owing to the MoCA 1.1 spec of the Mini and that the 4-tuner Roamios are limited to Fast Ethernet, an ECB2500C would be sufficient for networking just the Mini. That said, MoCA 2.0 adapters appear to be cheaper than the ECB2500C.

    Should you opt for a MoCA adapter lacking a second "RF/TV Out" coax port, you could just use a MoCA-compatible splitter to connect both the MoCA adapter and the Roamio OTA to the coax line; alternatively, you could use an antenna/satellite diplexer, connecting the MoCA adapter to the "SAT" port and the Roamio OTA to the "ANT (VHF/UHF)" port. The diplexer would produce less signal loss to the connected devices.

    And, yeah, the guy is quite wrong. He should've done the same thing you'll be doing, though he apparently has a router in the Living Room, rather than a standalone switch.

    p.s. Also, as one of the commenters to his review pointed-out, he also needed to add a "PoE" MoCA filter.

    p.p.s. Good god, "22 out of 22 people" had found that guy's review useful!

    Dang... I guess I have to buy a TiVo Stream as part of my "migration" too...

    I have gotten used to downloading shows to my Android smartphone to watch offline on plane flights... The "TiVo Stream" functionality comes built into the Roamio Pro, but I guess the OTA doesn't have it built-in... Shoot... Saving money apparently costs money...

    atmuscarella has got it right for this particular situation. I don't want to target the OP in particular, but why does everyone get so confused with MoCA? It's so simple, except for which models have a MoCA bridge built in and which don't. MoCA is very flexible since it can interoperate as a segment of an Ethernet network with an Ethernet backbone, or function as the backbone of a network with a bunch of small Ethernet segments, or whatever is needed in a particular application.

    Do the out ports work properly on these things? Maybe I'm getting confused with TAs, but I seem to think that there is a lot of loss on the output of these things. Not sure how it compares to a splitter, or if it's just an internal two-way splitter anyway.

    MoCA adapters with "TV/STB Out" ports supposedly divert the signals using a diplexer, rather than a splitter, so the losses would be lower.

    @MikeekiM, reviewing the thread, it's unclear how your OTA antenna signal will be routed to the Roamio OTA, or what service type you're using for your Internet connection and how that signal would be routed to your modem if using cable Internet.

    Key factor is that OTA antenna and cable signals can't coexist on the same coax run, since they use overlapping frequencies.

    Thanks for the thoughtful follow-up krkaufman!

    I have an indoor antenna attached to the Roamio OTA, as well as an ethernet cable coming from my switch. My guess is that if I connect that same switch to a MoCA adapter, and have the MoCA adapter feed the RG6 going to my TiVo Mini in another location, that I am good to go...

    Please let me know if my logic is solid here...

    Sounds good, based on what's been described.

    Cable internet should be fine with OTA. Cable TV will be bad since the OOB return frequency is usually 75MHz and could mess with OTA channels. Perhaps the cable modem has diagnostics indicating the frequencies used?

    Not from what I've seen for frequencies used for cable Internet, beyond just the return path, and the fact that few providers only send Internet signals down the coax now that they've gone digital. Plus the fact that the antenna signals could bleed back onto the cable provider's plant.

    Fortunately it's a moot point for the OP, having a dedicated antenna.

    OK... I have another question... I have one of my TiVo Minis in a location with both coax and ethernet... In fact, this TiVo Mini is sitting right next to my TiVo Roamio OTA, and is exclusively feeding my Slingbox.

    If I connect my switch-connected ethernet AND my coax to my TiVo Mini, will it be able to tap into my network via ethernet, and extend my network access over coax and effectively be my MoCA adapter? Or is the coax an "input" only port on the mini?

    I need to establish the MoCA network for the TiVo Mini in my MBR.

    Edit: Yeah, my guess would be that a TiVo Mini cannot serve as a MoCA adapter... If it did, I would think I would be able to find something with a Google search...

    Man, this Roamio OTA is costing me more money than I thought to get a like-for-like featureset with my Roamio Pro... :)

    No, a TiVo Mini can only connect to an Ethernet or MoCA network segment as a client; TiVo Minis lack MoCA/Ethernet bridging functionality.

    I like the Roamio OTA as a backup tuner and storage offload. If I had to choose one unit to keep would definitely be Roamio Pro. The ethernet is GigaBit, the MoCA is client or bridge, the output is component with no breakout cables. There is a noticeable difference between composite (on my Roamio OTA) vs component (on my Roamio Pro). Component on Roamio Pro vs s-video on S3 OLED is no difference. I have slingbox pros connected to all my TiVos.

    Unfortunately, the 6-tuner Roamios suffer relative to the Roamio OTA in one key aspect, the inability to tune from an OTA antenna source.

    Yes, I agree... I really, really, really (really) want to keep my Roamio Pro. I just cut the cord and don't have cable any more... But since this just happened, I am not sure if I will end up bringing cable tv back into my house... So maybe I keep it... It's just such an expensive doorstop right now... If I don't get cable tv back, then this receiver likely just continues to lose value over time...

    HDMI makes the composite/component issue moot... If I run ethernet to my MBR, I can avoid the cost of a MoCA adapter... And I guess I can live without TiVo Stream capability... I have my slingbox for video streaming (which I find superior to TiVo Stream)... However, I do love the ability to download content to my smartphone for offline playback when I travel... But I don't use it often enough to justify spending a lot of money on it...

    What is the benefit of GigaBit ethernet in the TiVo use case? Transferring content from one box to another, certainly... but if you are transferring to a non-GigaBit box, then that benefit goes away...

    Headroom for transfers and streaming (mini or other). I tested Pro to do 170Mps over MoCA 1.1 and I think GigaBit was a little higher, maybe close to 200Mbps. I like having the extra headroom so there is enough bandwidth to transfer shows and stream to minis at close to max the unit can handle. It is a simplistic calculation (there are various factors) but transferring from Pro to OTA with OTAs 100Mbps connection should still leave around 100Mbps for streaming to Minis.

    I run older Slingbox Pros with only analog inputs, both because that is what I started with, and because now that Sling is out of the game, I prefer units where I can connect to them without any dependency on Sling servers being active. Who knows when/if they will shut those down eventually.

    Depending on what stations you record, you might want to get the limited basic broadcast channels only option. It is usually something like $20-$30 vs $60-$100 for the normal packages.

    Speed of downloads/transfers and ability to support more Minis.

    Not going to work in any practical way. In theory, you'd have to notch out all the right frequencies for each, avoid injecting noise into the cable plant, and leakage from the antenna, and then if the cable company changed frequencies, you're SOL all over again. The combinations of cable, OTA, MoCA, and DirecTV SWiM that can work are:

    1. <=860mhz cable/FiOS video plus DirecTV SWiM with diplexer (no DECA or MoCA)
    2. OTA plus DirecTV SWiM with diplexer (no DECA or MoCA)
    3. DECA plus DirecTV SWiM
    4. OTA plus MoCA
    5. <= 1002mhz cable plus MoCA LAN
    6. FiOS video plus MoCA WAN plus MoCA LAN
