Today's homes have multiple TVs in various locations, which leads to the question of how to get a signal from one HDTV antenna to each television. Simply installing a TV signal/combiner can take the signal from one HDTV antenna and send the signal to each TV. You can purchase a splitter at your local hardware or electronics store that will connect two to four televisions on one antenna signal.

Skill level:

Things you need

  • Coaxial Cable Splitter/combiner
  • Pencil
  • Drill
  • 1/4 inch drill bit (masonry or wood bit)
  • Screwdriver

  1. 1

    Locate the area where the splitter will be mounted. This is where the cables from each TV and the HDTV antenna all come together in one location. Hold the splitter up to the wall and use the pencil to mark the location of each mounting hole on the wall. This will indicate where to drill the pilot holes.

  2. 2

    Drill a small 1/4-inch pilot hole where each pencil mark is.

  3. 3

    Line up the splitter with the drilled pilot holes. Insert a screw into each hole and tighten the screw into the wall, using the screwdriver.

  4. 4

    Attach the coaxial connector from the HDTV antenna to the labelled "Signal In" connector on the splitter. Thread the connectors together in a clockwise direction and then tighten the connectors down. Attach each of the coaxial connectors from each TV to the labelled "Signal Out" connectors in the same manner.

  5. 5

    Turn each of the TVs on and test for signal reception.

Tips and warnings

  • Do not connect multiple splitters to the same antenna as this will cause significant signal strength loss to each of the TVs.
