DTV Modulator Link - AV to RF Converter (DRF-30T) This handy device converts signal from RCA (the red, yellow and white plugs) into RF signal over a co-axial cable. This would allow you to change certain types of signals from satellite decoders and other media devices not traditionally distrubuted, to be shared through normal co-axial extensions to other TV sets in the home. It can also be used to distribute analogue CCTV systems. It also has application for use with older camcorders, game consoles and even your DVD signals. It is a low cost, easy to fit solution.
