Can somebody please explain to me how these work. Do they just send the tv picture wirelessly ordo they send the tv signal wirelessly?

I still don't understand, does that mean they share the aerial and they both tv's can have there own channel on, or can you only watch what the feed tv is watching.

No, they don't share the aerial, they are not TV tuners in their own right. What they do is transmit the video signal, i.e. the picture itself, that has been generated by the TV tuner inside a set top box. It doesn't have to be a TV-tuner generated picture though, as mentioned in post 2 it transmits any standard stereo audio and composite video signal. So it could be a VCR, a computer, a video game console...anything that has video output on it.

Typically, you will connect a video sender to a Sky box for example. The Sky box will be connected directly to your main TV by a wire, but there will be another TV somewhere else in the house with the receiver connected to it. Both TVs will show the same picture, i.e. the one generated by the Sky box.

You tend to get two unit's (A set made up of one transmiter unit & receiver unit) you plug (A SCART typically) from your freeview box (For example!) into the transmiter then the unit (As it allow's the SCART to "Pass through") into the back of your main t.v. (So you dont need a spare SCART on your freeview box!) you then plug the receiver unit into the back of your bedroom t.v. (Again for example) via the built in SCART plug. These systems allow you to watch digibox's or whatever source you plug in, in a second location, they don't allow you to watch two channel's sourced from the ONE bit of equipment plugged into them. I also forgot to mention that the unit's need to be powered by there own power adaptors, i.e. they are not powered by the t.v.'s they are plugged into. Hope that this has cleared up what they do.

No, they don't share the aerial. They are *video* transmitters, they transmit video. The signal that comes down the aerial is not video.

What you need is an aerial distribution amplifier/booster. I'm afraid it won't be wireless but at least it will allow you to run more than one TV off an aerial with no loss of signal. e.g. Argos product 5346903.

Is your reception not good enough for a TV top aerial at the second TV?

If you do not want to wire a TV aerial into the bedroom/kitchen/wherever or cannot for do so for some reason your options are a bit limited. There is no way that you can get the raw signals from the aerial into the other room using a wireless sender device.

The only option that may be open to you is to install a second Freeview box on the end of the existing aerial cable. Plug the SCART output of that into a video sender transmitter which links to a receiver connected to your second TV. Many makes of video sender also have a facility to send remote control signals back to the Freeview box so that you can change channels etc.

But to be honest this is more trouble than it is worth. And may not even work anyway. Video senders do not like walls and floors too much. Too many of either and the signal may degrade too much to be reliable. Plus they share the same frequency band as wireless broadband routers. So if you or your close neighbours have wireless broadband there is potential for interference screwing up the signal.

And if you have a third or fourth TV and want all of them to have their own Freeview receivers then you end up with a shed load of kit hiding behind the telly in the living room and finding enough clear channels for all the senders to work on is likely to be a nightmare!

By far the best option would be to get a professional aerial installer in and get him to fit a proper distribution system feeding the aerial signal into whichever rooms you need it.
