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 distributed, to be shared through normal co axial extensions to other TV sets in the home. It can also be used to distributed analogue CCTV systems. It also has application for use with older camcorders, game consoles and even your DVD signals to be distributed too. It is a low cost, easy to fit solution.

It has external setting for NTSC/PAL B/G, I, D/K, L, M, /NTV formats for global use
And the output channel is changeable so as not to clash with any other channel on the RF band - giving you a picture that is clear and free from interference.
