RF Demodulator Coax to HDMI UHF Modulator VHF Adapter Coaxial Converter for JVC Videodisc Betamax VCRs VHS Camcorder Video CD Player Magnavox Odyssey Atari 2600 to HDTV HD Digital Projector Monitor TV

Have 2 older TV's with RF inputs; both appeared to fail. Hooked this unit up, both still work using HDMI inputs. Comes with "Simple Guide" for North American TV's. Practically plug-n-play. Took a few minutes for the auto scan to run on the first one (an old Visio), then just plugged into the somewhat newer Phillips, both work great. Excellent picture, good sound. Will buy more.

Don’t do it. I thought I’d try even with the negative reviews because I’m usually pretty savvy. But this thing is a brick. Blue screen. Remote does nothing. Instructions are a joke. When I finally got it to work the picture quality was worse than without it.

Took a little bit of trying different things to work for a ColecoVision but at the end it works. If you are using it for the Coleco you will also need an old school RF adapter.

Did the auto scan with my Atari 2600 turned on as suggested by other reviewers. It picked it up and programmed a channel for it no problem. However I'm giving it 4 stars instead of 5 because it was unable to pick up my Famicom. Maybe if I messed with it more I would be able to get it to work but I didn't mess with it much because I have an AV Famicom that I can pipe into the system by other means.

Bought this to connect a set-top box to a TV. Worked "okay" for TV channels (images were fuzzy when used for streaming), but then it stopped working after just three days. Returned it.

Perfect! Works exactly as I needed it to. Hooked up the Atari 2600, fired up like it was 1983, Space Invaders never looked so good.

Does not work. I wanted to hook my old atari up to a newer tv. After searching forever and only finding modulators I finally came across this demodulator. There are no instructions with the unit. other than a piece of paper that says what each button on the remote does, and a on a very small piece of paper 3 "troubleshooting" steps. Which are not actually troubleshooting steps. I attempted to scan for a signal multiple times in multiple ways. I tried with 3 different Atari's connected, a woody, a vader, and a Jr. and it found the signal on none of them. In the end I may need to mod the systems with a composite board since there are no other demodulators I can see. For the record the Atari's work just fine when passed through my older surround system that has a 75ohm rf connector. But that unit is huge and I don't want to use it.

it's ok, it works but the quality is not great.
