Using Video Sender to watch Sky

[rushdenx1]

I have a Gigaair 2424 video sender. I want to watch Sky on a second TV. The transmitter and receiver each have a scart socket, but I do not know where to plug them in. The TV transmitting the signal has a Sky box and DVD/Video player connected. The TV has 3 scart sockets AV1, 2 & 3. The Sky box and DVD both have 2. Apart from AV3 all sockets are already used so I am presuming I will have to get a scart splitter, but which socket do I need to plug the video sender into so Sky is transmitted. The receiving TV has only 1 scart socket and is connected to another DVD/Video with 2 scarts. Where does the receiving video sender scart go. Once it is connected does the TV have to be tuned in to recieive the signal ? Any help would be greatly appreciated. Kevin.
