How to find the right coax cable digital splitter

Yet another topic there’s much less documentation on than there should be

If you have cable internet or are using the coax cable inside your house for MoCA networking, you might eventually want to split a cable outlet between 2 end point devices, e.g. a set top box and a modem, or a network CableCARD tuner and a MoCA adapter.

You’ll need a digital splitter for that, and the most important spec for the job is the frequency range the splitter is rated for. It must be from 5 to approximately 1000 MHz. I say approximately because some splitters that work are rated for 5-1002 MHz.

Splitters that have worked for me – most recently with an Actiontec ECB6200 – include the Extreme Broadband Engineering BDS102H, CommScope SV2G, and Regal ZDSB3DGH10. If you can’t find any of those or a splitter that meets the 5-1000 MHz spec, then get one from a cable company truck. I did this myself years ago by just hanging out in the cable company office lot until a truck came by. I told them what I needed a digital splitter for, and they tossed me a couple.
