This 'Magic Eye' remote extender lets you control the TV channels on your digital satellite box from another room in your house. The device connects between the coaxial cable and the aerial socket on the back of the TV. The Eye then sits on top of the TV and users can change the channel with the satellite remote without leaving the room.Power[tab]9Vdc from satellite box[br]Dimensions : main unit[tab]50 x 29 x 20mm[br]Dimensions : receiver[tab]18 x 29mmØ[br]Weight[tab]75g[br]Cable : specification[tab]3C2V
