I can go to any electronics store, drop down $20, and get a video converter that takes a set of RCA outputs (Yellow video, Red and white audio) and spits out a television signal on a coaxial wire. This is handy for connecting newer equipment to older television sets.

Is there a gadget I can buy that will do the same thing, but in reverse? That is, take a coaxial video signal as an input (such as from a TV antenna) and spit out the stuff on separate RCA yellow/red/white ports?

Yes. It’s called a tuner. Probably the easiest way to get your hands on one is to use an old VCR. Antenna goes to the antenna-in connector, and get your video and audio on the “out” jacks. You may need to poke the VCR/TV button to get your off-air stuff to appear.

Otherwise, stand-alone tuners aren’t terribly common things.

Balderdash. This is **G.Q.** , not **I.M.H.O.**. Please refrain from making statements like this unless you’re very very sure, ok?

You want to do this, and not have a huge box in the way? Call **Wolf Seeburg Video** at **(310) 822-4973**. As for **Peggy in Sales**. It costs $ 180.00, and is very compact. It comes with an AC/ DC power supply.

This is an extremely small RF Tuner box. It doesn’t “steal” scrambled cable t.v. signals. This device is entirely legal. All it does is exactly what **rjung** said he wanted to be able to do.

You plug in the RF cable, select a channel, and the RCA jacks out the other side feed pure Video and Audio.

I own one. It works just fine.

It also is a t.v. tuner, it can catch signals broadcast in the air and feed out pure Video and Audio as well. Ya wanted the Straight Dope? Ya got it. 🙂

Guess I stand corrected on stand-alone tuners. But I also stand by how uncommon they are. If a store sells things that plug in and make sound or pictures, odds are good that they sell VCRs. Even my grocery store sells them every so often.

Anything that I have to go to one specific person at one specific company for isn’t common, compared to something that I can get at any of six stores in a two block radius of where I’m sitting. No opinions are needed. 😉

The price also speaks to their relative rarity - $180 for a standalone tuner, or $43 for a [brand new VCR](http://www.walmart.com/catalog/product.gsp?product_id=2123644&cat=4564&type=19&dept=3944&path=0%3A3944%3A3987%3A77622%3A4564)? Unless the picture from the standalone tuner is really 4-5 times better than the picture from the VCR, you can be pretty sure that a lot more cheap VCRs are being cranked out than standalone tuners.

$180 is awfully steep.

You want [something like this](http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F003%5F010%5F009%5F000&product%5Fid=15%2D2525).

You can probably get something similar at the local Best Buy, Circuit City, etc.

If your TV has stereo speakers make sure to get a converter that supports stereo output over the coax RF connection to the TV.

No that’s what **rjung** already has. Takes an A/V source and converts it to an NTSC RF signal at the frequencies commonly referred to in the US as Channel 3 or Channel 4.

A nice one though. Two sets of inputs, S-video included.

He wants to take an RF signal at one frequency (pre-NES video game) or several (antenna or cable) and convert to A/V output. He needs to be able to select (tune in) a channel.

ACK! I misread that. Sorry about that.

I must admit, most vcr’s have tuners. However, they’re large and bulky and take up real estate in the media cabinet. My suggestion works and is incredibly small and discreet.

-shrug- It’s an option. I didn’t mean to suggest that using a vcr was not an option, sorry if it came off that way.
