View Full Version : Coaxial/RCA issues

I'm just wondering if there's any way to convert a Coax signal into a three-way RCA output(A two way would be sufficient, but three-way's better). This would be very useful to play older gaming systems like Ataris. Actually, my Dreamcast only came with a Coax cable so at this point I NEED a VCR to play it, which is really annoying.
Which raises another question: If there is no such converter box, would it be possible to disassemble a VCR and just use the Coax Input and RCA Outputs? If so, where would be a good source that describes how to do so without bowing it up?
Thanks in advance.

Not an RCA to Coax converter; I need one that does it the other way around. Coax to RCA. Essentially, a splitter.

and your tv doesn't have an input for coax? or is it being used for tv/cable currently?

if so, coax switches are, like, a dollar at radio shack. my family bought one in 1996.

i guess i don't understand why you need to go from coax to rca to get it into a tv. every tv made in the last three decades has had a coax plug.

Actually, the TV in my room doesn't have one.

But aside from that, I was really hoping for an RCA output so I could have it plugged into an input switcher. (I got one with four inputs, including component and S-Video)
Most HDTVs have coax inputs?

we are talking about the same thing, right? i honestly thought tvs were required to have coax inputs. i've never seen one without one. my dad has one from the seventies with a connection, for goodness sake.

if that's what you need, and you don't have it anywhere on your tv, i don't know how to help you. there are virtually no tvs out there without this connector on it SOMEWHERE. which is why you haven't been able to find the converter, i'm assuming.

Every HDTV I've seen has had a coax input..

Hmm, yeah, I guess I'll just need to get a TV with a Coax input.
I checked at a few stores and found the thing you mentioned, Prophet, but couldn't find the opposite. One guy I talked to said I might need to go to a specialist store to find it, if it even exists. But, so long as I can get a TV with a Coax input, I should be okay.

Thanks!

i'm really surprised your tv doesn't have that input.

ok maybe i'm missing the point.. but you mentioned Dreamcast.

the thing outputs native VGA with the right cable..

Why not just get the right cable to hook up your system rather than trying to retrofit over a crappy connection in the first place?

Yeah, I went to a specialist store, and they were selling Dreamcast VGA cables for $20, but I thought that if I could find such a box, I could use it for my ColecoVision as well, and potentially any Atari's/old consoles I may get.
But so long as a new TV has Coax input, I should be okay.

getting Non-RF out of Coleco/Atari is a whole other proposition.

It can be done, but requires modding the physical console:

The specific device you would be looking for is an 'RF Demodulator'

They are not cheap.

That's the cheapest one I could find at 54$ Ebay would be my next bet.
