Switching voltage for polarizer

Switching voltage for polarizer
Most satellite receivers provide a direct voltage at their coaxtat output which, depending on the plane of polarization of the set program, is either 13/17 V or 14/18 V. This voltage is applied to the external unit via the coaxial cable to enable the polarizer to be switched over. This functions very well as lang as the polarizer is integrated in the LNB.
