Indoor Wireless Cable TV Transmission
I would like to have something plug into my cable tv jack that can
transmit the cable over to another antenna that is plugged into the VHF input on the VCR in another room. That way I would not have to run cable from the cable jack in my bedroom to the home theater system in the living room. Does anyone know of any items that would allow this? I think I need a tranmitter and a reciever, but I do not want to change channels at the transmitter - I want to be able to change with the reciever (plugged into the VCR). Any ideas?? Thank you very much for your help and time!! Randy N |

Well, the problem here is that the bandwidth of that coaxial cable coming out of the wall is probably on the order of 200-500MHz, depending on how many channels you cable TV provider gives you. You aren't going to find any reasonably priced device that'll transmit that much bandwidth wirelessly. Any ideas?? Hire some talented kid to run that cable for you for, say, $50-$100? You might want to take a mozy around the exterior of your house and see where the TV cable is (I'm assuming your house wasn't originally built wired for cable -- otherwise I can't imagine there wouldn't already be an outlet in the living room); you might find there's an opportune place to tap into it a lot closer to your living room than your bedroom is. ---Joel Kolstad |

Transmitting the whole content of the cable-TV feed is simply not going to be possible for you to do. You're talking about a massive amount of bandwidth / frequency spectrum - each station is about 6 MHz wide. You cannot simply hook the cable up to an antenna and "beam" the RF in the next room. Well, you can, but it'd be quite illegal. Many cable channels use frequencies which are _not_ authorized for broadcasting... they overlap the amateur 2-meter band, aircraft and public-safety frequencies, etc. Cable-TV companies have to go to some lengths to keep these signals _inside_ the cable system and keep them from leaking out into free space. Although it's not what you want to do, the best you're going to be able to manage is probably something like a remote-controllable tuner at the cable-TV jack (think "An old VCR from the thrift store, which has a working tuner and a busted tape mechanism, costing all of $10 as-is") which has a composite-video output, plugged into one of those little 2.4 GHz Part 15 video transmitters. The 2.4 GHz video receiver's composite video (and audio) outputs would be plugged into your VCR's A/V inputs. You're likely to find the picture quality, and reliability of this arrangement to be less good than you'd like. I used to use something like it to remote-view a TiVo system, and soon decided to switch over to a wired-in arrangement. -- Dave Platt AE6EO Hosting the Jade Warrior home page: http://www.radagast.org/jade-warrior I do _not_ wish to receive unsolicited commercial email, and I will boycott any company which has the gall to send me such ads! |
