Reply to comment by jaxclayton in Can I hook modem up to a coax splice I found behind a blank plate? by jaxclayton

They make connection testers just for this purpose. You plug one piece into the end of the cable and the other piece (of the 2-part cable tracer kit) gets held near suspect cables and makes a noise when you've got the right one. You really only need to find out where the other end of the splice is, so I'd start with your utility closet or anywhere you know there's a splitter

That’s the thing, I haven’t seen any other coaxial cables in the house, so I would know what other end to test
