I work as an electrician. I used to use much more expensive connectors and splitters. Whenever a customer had a problem and called their cable provider (usually Comcast). Looking for an easy fix, the first thing they did was cut my connectors and replace my splitters, although to my knowledge this was never a problem. I am now using these splitters and these connectors https://www.amazon.com/gp/product/B00FNX8V3C/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 These are the same parts Comcast uses so they don't suspect them anymore.
