We're moving to Comcast from DirecTV and picking up four TiVos in the process. Should the following scenario work to get all the TiVos talking to one another and the outside world?
Premiere #1 (2 tuner): connected to network via switch #1
Premiere #2 (2 tuner): connected to network via MoCA adapter #1
Premiere 4XL: connected via coax only (using inbuilt MoCA adapter)
Premiere 4: connected to MoCA adapter #2
MoCA adapter #2 connects to switch #2
Premiere 4 connects to switch #2
(switch #1 and switch #2 are each connected to switch #3 which is connected to the DSL modem; unfortunately switch #1 is 100mbps)
Do I need MoCA adapter #2? or can I just plug the Premiere 4 into switch #2 and the coax line and have it shuffle data between the MoCA and Cat6 sides?
I think the coax cabling will go like this (reusing RG6 currently in use for DirecTV):
Cable drop --> MoCA POE filter --> 3-output 2GHz splitter (outputs A, B, C)
A --> MoCA adapter #1 --> Premiere #2
B --> MoCA adapter #2 --> Premiere 4 (or leave out MoCA adapter #2?)
C --> 2-output 2GHz splitter (outputs C1 and C2)
C1 --> Premiere #1
C2 --> Premiere 4XL
Do I need to be concerned about signal loss from the splitters?
What about cable length? -- distance from the tap to Premiere #1 and 4XL is about 120'
Since I'm reusing existing cables, I need a barrel nut / splice in both line B and line C (connecting the cables that are on either side of a couple of multiswitches at this point). Will I need to worry about signal loss there?
Thanks for any help / insight you can provide (I'm new to the whole MoCA concept).
