Freeview provides the United Kingdom’s free over-the-air digital television service, including all the main BBC and independent television channels. To receive the service, viewers need a correctly aligned television aerial connected to a Freeview-equipped TV set or Freeview set-top box. You can run two Freeview boxes from a single television aerial by installing a coaxial cable splitter on the aerial’s down cable and running an additional cable from the splitter to the site of the second Freeview box.
Calculate how much coaxial cable you will require to run an additional line from the coaxial entry point to the site of each Freeview box. Use a tape measure to calculate the distance of the cable run. Allow 4 to 5 feet of extra coaxial cable as a margin for error.
Unplug the incoming coaxial cable (running from the TV aerial) from the input socket on the back of the existing Freeview set-top box or TV set.
Mount the splitter device on the wall or fix it to a baseboard. Use the supplied screws and a screwdriver to secure the unit firmly in place. Mount the device out of sight — for example, behind your TV set.
Plug the incoming cable into the “Input” or “Antenna” jack on the splitter device.
Install the additional run of cable from the splitter location to the site of the additional Freeview box. If necessary, use an electric drill to bore passage holes through ceilings or walls. Fix the cable with cable ties or cable clamps placed every 3 feet along the cable run.
Screw F-type cable connectors onto each end of the newly-installed coaxial cables. Skip this step if the cable came supplied with connectors already fitted.
Plug one end of the new cable into a free “Output” socket on the splitter. Plug the other end of the new cable into the “Input” or “Antenna” jack on the back of the second Freeview box.
Plug one end of a short coaxial cable or fly-lead into another free “Output” socket on the splitter. Plug the other end of the cable into the “Input” or “Antenna” jack on the back of the original Freeview box. Most short coaxial cables ship with the connectors already attached. If not, screw an F-type cable connector onto each end of the short cable.
Use a shielded splitter device that protects against interference and equally balances the signal strength between all outputs. You can buy splitters with two, four or even eight outputs to run multiple TV sets or Freeview boxes from one aerial. An amplified splitter might be necessary if you want to hook up three or four boxes to one aerial.
Disconnect the Freeview boxes and all TV equipment from the main power supply before installing the splitter.
