Went in my local Game today found a basket full of RF TV Adapters reduced from £4.99 to 98p.
This adaptor allows you to connect your PlayStation 2 console to a television via the aerial socket.
Intended for use with televisions that are not equipped with modern AV inputs, such as phono or scart sockets, or where these sockets are being used by other AV equipment.
* Simple to install:
Make sure that your television and console are switched off; Remove the TV aerial lead from the TV's aerial socket; Plug the cable of the adaptor marked "TO GAME" into the back of your PlayStation 2 and connect the adaptor cable marked "TO TV" to your TV's aerial socket. You may also reconnect the TV aerial lead into the "ANT IN" port on the adaptor, this will allow normal TV reception through the adaptor. TV or PlayStation 2 selection is then made via the AER / GAME switch on the adaptor. This adaptor can also be used with PSone and PlayStation consoles.
