Re: 4 TVs & modem...how to run

Actually its a myth that a modem requires more signal than a set top box. Its in fact the opposite. But its not killing anyone to believe that so life goes on.

While it's true that most cable modems will work OK with input levels down to -10 dBmV or even less, if those levels are the result of using a many-way splitter, you need to make sure that the upstream power levels of the carriers the modem needs to transmit back through that loss do not start exceeding +52 dBmV.

Agreed, but I would even put that at 50 dB to even more so allow for the inevitable fluctuations.
