Can I demodulate a coax signal that I modulated at source using an RF Modulator?

Question

I put an RF Modulator (ch.3) on the a/v signal from my entertainment center and fed coax in the wall over to the TV location. If I get a new, possibly HD TV that does not have a coax input, How can I get the signal off the modulated coax at the TV location to feed new TV component or other inputs?

Thanks in advance; and I can't easily re-wire the wall, which I know I'll need to do for HD.

Answer 1

If you really want to do this, buy a cheapo VCR to do the demodulating for you. However, since you are planning on an HDTV, I'd rewire the wall first so you don't have to even do the demodulating. ( I am assuming that the HDTV you are looking at that does not have a coax input is actually an HD monitor???)

Answer 2

Apparently there are RF-input demodulators available; here's one i found by googling "RF to video demodulator": http://www.svideo.com/demodulator.html

I don't understand what you mean by a "new TV that does not have coax input". All new TV have coax antenna inputs, which will accept your modulated signal. You will not improve things (in fact you'll make then worse) by demodulating and feeding a video input. Of course, this setup will not provide HDTV operation; I don't know of any HDTV modulators, and if they do exist, are probably very expensive.
