Hi all,

Is there a device on the market today that allows me to attach the transmitter to an RF aerial socket and the receiver to the RF socket on a TV in a different room?

IE:

-------- = wired

~~~~~ = wireless

Aerial on roof---------RF socket in wall------ Transmitter ~~~~~Receiver----RF socket on back of telly

i know a digisender can do a similar thing with the use of a freeview box, but would like to use the receivings TV's own builtin Freeview.

I have found one item that could do it but its french and i don't know the availabilty of it over here:

hope this make sense

thanks

If you mean re-broadcast the UHF signals from the aerial to somewhere else then that is illegal without an Ofcom licence, which you are very unlikely to ever get. And there is no device I know of that can do the job using the free to use bands such as the 2.4 or 5.8GHz bands used by didsenders.

The device you linked to is essentially a TV tuner and digisender in one box. If it is designed for the French market it may not work properly in the UK.

And is there any reason why you could not simply run coax cable from the aerial you already have to the second room?

I'm not too clued up and don't have the DIY skills to hardwire the house with coaxial cable to sort the problem

Unfortunately if you want to have TVs in several rooms then running cables is the only really viable option.

The only wireless solution is to stack as many STBs as you have TVs in a corner somewhere daisy chained off the one aerial feed. Then attach each STB to a wireless audio video sender. Unfortunately it is prone to several problems. The major one being there are a very limited number of channels available. Made even worse by the fact the 2.4GHz models share space with wireless networking products. So there is massive potential for interference, non working and ultimately disappointment.

The simplest solution is to fit a distribution amplifier as close to the aerial as possible. A masthead unit right up on the pole close to the aerial is best. Failing that run the cable into the loft and distribute from there. Then run cables out to the various rooms.

Eog,
As I understand it you want to send the signal to just one TV, right? If that is correct then yes, this can be done.

Firstly some good news. You're not going to be breaking any OfCom rules.

The reason is that you won't be rebroadcasting the RF signal in a form that can be picked by a TV aerial. That was the problem with early RF TV senders: Next door could pick up your TV signal (and anything you were broadcasting) on their portable TV. That doesn't happen with the new style video transmitters.

If your interested I have a video transmitter/receiver kit that will work with an aerial signal. As you know already, most only work with the SCART output from a VCR/DVD/Sky or Freeview box. It was bought for a project that never went ahead. It also passes remote control signals back to the source end which is useful for the future. Check out your private messages.

Regards

Chris

From my reading of the OP Eog wants to send the raw RF signals wirelessly from aerial to TV so that they can be processed by the tuner built into the TV. I don't know of any device that can do that (which is available for domestic use anyway). Especially not one that can handle a digital multiplex. Or indeed all six multiplexes at once. Which is what would be needed if I have read the OP correctly.

The device linked to in the OP is basically a TV tuner with built in AV sender which is not exactly the same thing but is probably the nearest you are ever likely to get.
