2.5 moca extension

[art3276]

When I bought my house the satellite tv antenna was mounted on the roof of a detached garage with RG6 quad shield cable going to the receiver underground to the house. I didn't use the dish so I repurposed the cable for MoCa 1.0 protocol to get network connectivity to the garage. So I have on adaptor near my switch in the house and another in the garage, works as it should. I added a forth bay on the detached garage and additional out building which I would like to add network connectivity to both and at the same time upgrade to MoCa 2.5. The added sections I plan to use RG11 and daisy chain from original location in the garage. Can that be done or do they have to be all home runs to the original garage location?

daisy chain using a moca 2 rated splitter is one way. Other way is to do point to point dedicated coax runs and using a Gbit switch to connect the moca modems to the same ethernet. Requires one more modem and a switch instead of a 3+ port splitter.
Upgrading is just changing out the modems if you want all nodes to have same speed possible.

Is the power in the existing garage and the new out buildings fed off of the same breaker panel or do the out buildings have a sub panel with separate earth/ground rod ?

I will go ahead source and get the MoCa 2 rated two way splitters and try that. Each location has it's own panel and ground one building has it's own electrical service on a different distribution transformer. The new building will have the RG11 routed from the existing garage underground through the basement of a rental house on the property and then underground to the new building only because the path is available. I want connectivity to the new building for environment monitoring, mesh wifi, security lighting switch control, 3 or more Hi Res IP PTZ's. Maybe long term run 10g fiber.

You are likely to get a ground loop then if both ends are earthed through the power supply and cable. shielding. Shields should only be earthed in one location for each cable run. No easy way to tell how severe and it will change with soil conditions. i would jump directly to fiber and forget MOCA. Pick a fiber spec that will work with your current equipment (at least Gbit/s) and leave a pull cord in the conduit in case you want to replace the fiber sometime in the future. ATT's fiber drops are designed for aerial so they have a support wire and are easy to pull without damage. Fiber does not like to be stressed when pulling so use long radius ells (radius >> bend radius limit for the fiber cable) or two 45 ells to make any turns.
