I have a projector that only has composite inputs. I need to get an antenna signal into it. How do I do this? I was thinking a coax to composite converter. Do these exist?
Craig beat me to it.
The Antenna signal is called "RF". It has a bunch of stations. This means you need a tuner to be able to pick one. Then you need the circuitry to convert the one station worth of signal to composite video.
This is almost exactly what a VCR does. (plus the ability to record of course.)
