Technically, TV splitters are capable of both splitting and combining coaxial cable connections. When used backwards, or as a combiner, TV splitters can join the input from multiple coaxial sources and route the signals through a single coaxial output, useful for situations where you're short on coaxial inputs. And using your TV splitter/combiner as a combiner is just as simple as using the device as a splitter.
- Skill level:
Connect a coaxial cable between your the "TV/ANT" port on the back of your television to the side of the TV splitter that only has one coaxial port.
Connect one end of a coaxial cable to the coaxial wall port you use for cable television, and attach the other side of the cable to one of the coaxial ports on the dual-port side of the splitter.
Connect another piece of coaxial cable between the other port on the dual-port side of the TV splitter and the coaxial port on your indoor OTA (Over the Air) antenna. If you have an outdoor antenna already set up, simply connect the port on the splitter to the coaxial cabling already in place.
