The TechniSat 4-way splitters are functional within the frequency range 40-2150 MHz. They are used in the distribution of the 1.satellite intermediate frequency and for distributing the combined frequencies of terrestrial reception and the 1.satellite intermediate frequency. The splitters are equipped with F-connectors on both the input and output sides. In addition, the 4-way splitters are each equipped with a unidirectional circuit pass, facilitating the simultaneous supply of power to an LNB connected to the system.
