The Channel Plus 2514 DC/IR Passing 4-Way Cable Splitter is a small but powerful device for combining signals or extending their reach to more equipment. Use it to split a single coax cable signal across four more out-going cables so it can be received by more TVs or a cable modem. It can also combine signals from multiple sources onto one coax run. Use a DC passing splitter whenever DC IR signals are present on the coax. It is suitable for antenna and coaxial operations. This DC IR passing coax splitter combiner has side brackets that allow it to be mounted on the wall or other location, keeping it securely in place.
