If I add another aerial connection to my splitter in the loft will this effect the picture on televisions I already have connected. At present it totals 4. I intend to put another lead from the loft down the outside of the house through the wall and fit a new socket in the small bedroom.

no I've just done the same but with a twin outlet splitter not just twin aerial plug. The twin splitter fittted to the main splitter and to two tv's aerial plugs fitted to the twin splitter outlet sockets, neither tv effects the other.
