Coax to Composite converter?

[mdezrin]

I've got an old 32" tv in a work room. There is 75 ohm coax coming from the wall (being fed from a DTV tuner shared with another tv. The 32" target tv's coax input is broken. the tv does have the traditional composite inputs. Is there any inexpensive type of conversion available from coax to composite to be able to hook up the tv?

alternatively, radio shack has an hdmi to composite converter. so, is there a 75 ohm to HDMI converter?

thanks!

They carry different types of signals. The 75 ohm coax carries a wideband signal representing multiple channels (up to hundreds). A tuner is needed to isolate a single channel. The RCA composite cable carries a signal for a single image.

Your best bet for a converter is to find an old VCR. Switch its tuner to channel 3 or 4 (whichever the DTV tuner is putting out). Then plug the TV's composite inputs into the VCR's composite outputs.

There are RCA to HDMI adapters since you're going from a single signal to single signal. But 75 ohm is designed to carry hundreds of channels. You'll still need a tuner to isolate a single channel (usually 3 or 4), at which point you might as well just plug it straight into the TV's composite inputs.

If you have or can find an old vcr (the tape part doesn't need to work) you can connect the DTV to it, set it to channel 3 or 4 and take the composite video and audio from it to the TV. Another DTV box with composite out would also work.
