Ok, I hope I can explain this clearly. The cable tv company has a cable
coming to my house and going under my porch. There it hits a cable splitter
with 2 lines going to 2 different rooms. The cable coming in is a single
"strand". One of the room lines is also a single "strand". The other is a
double "strand", but only 1 strand is connected to the splitter. I imagine
this is leftover from when cable boxes had A/B knobs. In the room, both
strands come out of the wall, but only 1 has a proper connector on it, the
other strand is just cut.

Will the 1 "strand" work like a single cable, or will it need to be
replaced?


Hi,
What do you mean by strand? Coax has outer shield and center conductor
which could be solid single wire or multi-strand wire(think skin effect).
