Refer to picture of “Wifi ready “ label which is under cabinet above tv . There is a cable there but where does the other end terminate. I don’t see any thing on roof

While trying one last time to try to figure out how to get sound for tv to camper speaker through convex (I gave up and using a sound bar) in the wiring mess I found a loose coaxial cable not covered to anything. It is small in size. Not normal size like cable for satellite. Does anyone know what it is for?
