RF (or Radio Frequency) is a method of transferring audio and video from a programming source, like a broadcasting station, to a television or other electronic device, typically with a coaxial cable. A VGA (Video Graphics Array) connection is used to transfer video signals from one device to another, such as from a computer to a monitor. VGA plugs have a distinctive shape and nine brass pins. Converting RF signals to VGA requires an RF modulator and a VGA-to-S-video adaptor, both available at electronics and computer stores.

  1. 1

    Connect the coaxial cable carrying the RF signal to the input jack on the RF modulator. The coupler on the end of the cable turns clockwise to secure it to the jack.

  2. 2

    Connect the DC power cord to the modulator and to a wall outlet.

  3. 3

    Insert the S-video plug on one end of the S-video-to-VGA adaptor into the RF modulator's "OUT" jack.

  4. 4

    Attach the VGA plug on the other end of the S-video-to-VGA adaptor to a compatible video device, such as a computer monitor, then secure the plug to the jack by turning the locking screws clockwise on each side of the plug.

  5. 5

    Turn on the VGA device and the RF modulator to view video from the RF signal.

Tips and warnings

  • VGA cables deliver video only. The audio cables on the adaptor must be plugged into a compatible audio device in order to hear sound from the RF source.
  • The S-video-to-VGA adaptor cable contains the necessary plugs on each end for completing the connection.
  • Disconnect all devices from power outlets while attaching AV cables and adaptors.
