I have a house with 5 unlabeled runs of coax to a centre point. One run moves the sky satellite from room A to room B. I want to split this signal and send it to room C so I will split it but with 8 other wires testing by moving a decoder round is a pain in the butt. Am I right in thinking, if I place one of these Satellite Finders on the end of the signal in the bedroom it will tell me the sattelite signal is running through this wire now??
How about. Disconnect the 5 ends at the common point. Connect a small cheap buzzer on the other ends in turn and connect a battery to each in turn at the common end to see which cable activates the buzzer. Even cheaper if you have a multimeter. Short out each end in turn and check which cable is shorted at the common end. Then label them.
