Do you suggest that I move my cable modem to the free -7dB output? And then put a diplexer at each place as you suggested? (Actually I wont need a diplexer at the location which has just the cable MODEM right - I might need a splitter here - as MOCA and cable modem are probably on the 1+ GHz frequency?)
And finally if I wanted the actiontec on all 3 locations, there is no way for me to have all 3 of them on a single splitter (by definition its only 2 outputs for a single splitter right). how do you approach that - as I think I might have to install actiontecs on all 3 locations..
The cable modem runs in the TV part of the band, below 1Ghz, not the satellite part of the band, so you should treat the cable modem the same as video equipment. Only MOCA and satellite run above 1Ghz.
The best MOCA performance will come across a single splitter, but it will work across multiple splitters, with some loss in signal strength and potentially in speed if error correction has to kick in.
For your initial 2-way hookup you should use the -7db jacks, but you can also experiment with seeing how well it works between one of the -7db jacks and the -3.5db. If it works well enough, you may want to evaluate the relative download speed with your cable modem connected to the -7db and the -3.5db.
Everything is a trade-off: your computer will run its fastest on the -3.5db, but your MOCA network may run slower.
However, since MOCA is several times as fast as cable internet, you may well decide to give the additional speed to the cable modem!
Unless you're networking video stored on your computer, the most important speed is that of the slowest link - your connection to the outside world - if you're streaming video coming from the outside world.
