How To Connect 2 TVS with a tv splitter. Screw the coaxial cable into the "Input" port on the splitter. It will be on the side of the splitter with only one coaxial port. Screw two coaxial cables to the "Output" ports on the other side of the splitter. Connect the other end of one of the two "Output" coaxial cables to the "Antenna In" port on your TV. TV is already connected to the original signal source. If there is no existing coaxial cable running from the source to a TV set, an additional cable is needed to connect the source to the input jack of the splitter. Users should first unscrew the coaxial cable from the back of the existing TV set. The splitter is then mounted to a baseboard with drywall screws within reach of the original coaxial cable. The cable is attached to the input jack of the splitter. The short cable is connected to one output jack of the splitter. The other end connects to the original TV set. The previous step is repeated with long cables for additional TV sets.how to connect multiple tvs to one antenna Coax straps can be installed to support cables between devices. how to hook up 2 tvs to one receiver. how to hook up 2 tvs to one dish receiver. how to connect two tvs to one directv receiver. connect 2 tvs dish network are direct tv.
