I say, nope.

My dad (the cable man) says: Nope, and get the drill and start pulling wire!

To deliver an entire cable system, no. One channel at a time, yes. Meaning there would be a tuner of some sort where there is cable, and the selected channel would be wirelessly transmitted to the receiving set, and IR commands sent to the tuner device.

As Classicsat said here is one option, x10 has a wireless sender for one channel or input at a time.

This X-10 things looks promising, but what about looking at it from another angle, is there such a thing as CATV over IP? Personally I dont even have cable at home, this is for an extended care facility, if I can save them a few bucks it can go into more critical repairs.

Yes and no, You can stream a channel over a network, wired or wireless using a tuner card and a media center at the TV. several people sell media centers. The local phone co. (AT&T) delivers cable thru the phone lines here. comes in on a phone pair and each set has a box like a cable box that selects the channel. The signal is sent to the neighborhood by way of fiber and the last 4000 by twisted pair. Picture looks good but there are limitations. BTW those still receiving TV by way of an antenna, get yourself a digital TV or a converter box. most stations are broadcasting several digital signals (more than one) and the picture will knock your socks off!

There is something called an "amplitude modulated link" or AML which is used by cable companies to distribute cable TV signals to remote locations. But I don't think this is applicable to what you are looking for.

The bandwidth of CATV is so high that it's wildly impractical to transfer it over air with any sort of consumer level radio transmitter- best you can really do are solutions that pick one channel and transmit it.

I have a really cool device called SlingBox on my TV- it hooks up to your cable box/DVR (or uses its own internal analog tuner) and puts it on the internet. You can go anywhere in the world, pop open your laptop, and watch what's on your TV at home. It's compatible with wifi, and allows remote control of the cable box/dvr/tv through a virtual remote control and IR modulator. (When my [spoiled rotten] kids are crying that their show's over and they want me to put on another show from the DVR, I can be a lazy-ass and sit at my computer, pull up Slingbox and remotely control my DVR to put their show on.)

So, in short, this would still not let you wirelessly stream CATV to a new location. But if you had a computer in that location, you could watch TV on it through your home's wifi network.

What exactly are you trying to do? Bring cable TV to where it isn't, or add additional channels to an existing cable installation?

Is this system going to use existing TV's, or will it be digital only? Does each location have to be individually addressable? Does each location need to be able to watch different channels?

Questions, questions, questions. smile
