A dual passive signal splitter, designed for connection with cascade taps P.121 or multiswitches. This is de facto a system of multiple 2-way splitters in one unit. DC is passed from outputs to inputs.
Satellite inputs are used for connection of LNB, terrestrial input for connection of TV or FM antenna or a preamplifier. The inputs of the unit can also be connected to the outputs of suitable amplifier, e.g. P.140-M or P.140-M SAT.
The units are stackable onto the top of each other to allow modular multi-satellite reception systems.
