Hi,
Thanks for the reply.
Hmm in that case I could prob get away with maybe just using the 3.7Db splitter from the outside cable to it then just connect the CM and STB to it?
My parents have an STB downstairs and I took the cover off the wedge box on the wall and there is a chunky looking device in there with an F connector at the bottom which feeds the STB, looking at the diagram on it I would say its fused, then again im no expert
Cheers
Matt
