  1. 1

    Check the coaxial connector is securely attached to the coaxial cable and there are no strands of wire braiding visible. If the cable is loose or, appears to be poorly fitted, rewire the coaxial connector and plug.

  2. 2

    Locate the input socket usually situated on the reverse of your appliance. It will be labelled aerial, antenna or similar.

  3. 3

    Push the coaxial plug into the socket. Turn on your appliance to check you have good reception.

  1. 1

    Examine the coaxial connector to ensure the coaxial cable is securely fitted to the cable. If it appears loose or wire is visible, it needs rewiring.

  2. 2

    Locate the input socket on the reverse of your appliance. It will be labelled, but the descriptions vary. Unlike the push-in coaxial connectors, screw-in types can connect to input and output, so make certain of the cable's purpose. They will always be labelled "in" or "out" and some will have" video in" or "antenna in."

  3. 3

    Use the input socket if the coaxial cable runs from your antenna or satellite dish. If you're connecting from a receiver to a TV, use the output socket on the receiver and the input socket on the TV.

  4. 4

    Screw the coaxial connector firmly in the socket. Repeat if you're connecting to two appliances. Turn on your appliance to ensure to have connected the cable correctly.

Tips and warnings

  • You can buy coaxial connectors that fit two cables together for extra length. They are in the shape of a barrel. Use the push-in type for use with a TV antenna or the crew-in type for satellite or cable TV.
