Direct TV receivers allow you to watch satellite TV channels via a dish that is installed with a view of the southern sky. If you have one receiver, but want to hook up another TV in a different room, you can do so with a splitter and coaxial cable. However, if you are using one receiver for two TVs, both TVs will show the same channel.
Purchase a 2-way splitter. The splitter will have one input and two outputs.
Place the coaxial cable that is bringing the signal into the room on the input of the DirecTV receiver.
Place a shorter coaxial cable on the output of the DirecTV receiver. Attach the other end of the coaxial cable to the input of the splitter.
Place a coaxial cable on the output of the splitter. Run the other end of the cable to the first TV. Place the cable on the input of the TV.
Run the second coaxial cable from the second output on the splitter to the input on the second TV.
Turn on both TVs and the DirecTV receiver. You will have the same channel on each TV. Make sure that each TV is tuned to channel 3 to receive the picture.
