Splitting incoming xfinity signal

Hello. I currently have xfinity gigabit internet and Directv satellite TV. I have 9 coaxial wll outlets in the home: one connects the xfinity internet modem to the xfinity ground cable outside (it is a single connection outside), while the other 8 connect outside the house to the directv equipment. I want to switch from directv to X1 tv. After the switch I will end up using 6 of the 9 coax outlets at most  for now (1 for internet and 5 for tv), although I may get 2 wireless tv boxes which would reduce use to just 4 of the coax outlets. What is the best way to split the incoming ground cable to the separate coaxial outlets without a significant (if any) loss of signal to either the modem or tv?   I have the directv splitters outside, but I have read that they may not be good for xfinity.
