Are terminators suggested/needed on jacks inside the home?
This is really a system by system question. In areas where there is potential for a lot of noise (metro areas, high population), they may be necessary. From what I’ve seen, generally no. I suggest that instead of leaving open jacks, that you just disconnect the line and use a smaller splitter. Not only will this prevent ingress from unused jacks, but it will also send more signal to the used jacks.

We actually require the termination of any open port or wall jack in the home because of leakage and ingress problems. Having an open port acts just like an antenna and ends up backfeeding signal back into the system. One noted case was a customer having problems with their modem dropping off during the day time. We re-wired his house from tap to all outlets to try and fix the problem. After about 4 weeks of troubleshooting and gettin
