There are two cable signals entering the house - Spectrum's ISP+landline signal and a digital TV antenna signal. For now they are routed to two different locations. The Spectrum signal provides internet connectivity to a wireless router. My computer is connected to a port on the router. This is all good.
We're considering relocating my computer into the room that receives the digital TV signal. It would be really handy if there is some way to combine the Spectrum & antenna signals at the service entrance and then split the signal back to separate Spectrum & antenna signals in the TV room. (Spectrum signal would then go to the relocated router, antenna signal to TV.) Is it possible to combine then split signals? Or do I have to crawl around under the house and rewire stuff?
