Advantages:

  • - designed for distribution networks of 8 polarizations of intermediate frequency of СТВ signals and terrestrial TV signals up to 32 subscribers according to “star” distribution scheme;
  • - integrated power source for remote power supply;
  • - possibility of the power supply for pre-amplifiers via input of terrestrial TV;
