Just curious, since one can easily do the whole shebang.
I need to install a second cable modem at my house. One will feed my Internet and the other my cable phones. The single modem I have now is fed through a "tap" which is a Regal ZDRDCT1-6, with the tap port feeding my TV and the OUT port feeding my cable modem. Since I now need to split again, can I just put a standard 6 dB splitter on the OUT port of the tap and feed two cable modems with it? My single cable modem now sees a signal level of -6dBmV with a S/N ratio of 38 dB. I guess I don't know what the difference is between a "tap" and a 6 dB splitter.
