Configuration for two-four Sky, Sky+ or Sky HD decoders
When you intend to have two (or more) main locations for Sky, Sky+ or Sky HD decoders
you need to run a total of four satellite grade CT100 aerial cables to each main location.
You will be able to control up to four Sky, Sky+ or Sky HD decoders using the tvLINKS
and Global Super Plus Combiner. These use the coaxial cable eliminating the need for
additional cables and control systems.
