Currently, I have already ran my own coax from the street into the house all the way to my modem that is providing me internet. I'm looking to bundle TV and Internet and need to know what the process is adding the two TV's to my service. Is it as easy as adding a splitter in the attic turning my main trunk from the street into a three way?
TLDR: I have xfinity internet with my own cable ran, how do I add two TV's to my existing service?
Solved! Go to Solution.
Yes. Use an unbalanced 3-way splitter and put the modem on the -3.5 dB leg and the cable boxes for the TV's on the -7 dB legs. As long as the incoming signal strength is adequate, it should be fine.

Thank you very much for your prompt and informative response, regarding the incoming signal strength how would I know if it is adequate? Here is my Arris SB6183 information on the ~200Mbps service:

You can't know for sure until you try it and see. The downstream is on the weak side but is still within spec. Give it a shot.
