Cascade multiswitches MS1751, MS1752

type of equipment:




    • cascade 16 satellite polarizations and terrestrial TV signal distribution system for a flore-by-flore wiring or arrangement of a star distribution scheme
  • effective usage of power supply sources: multiswitches do not consume current from the backbone
  • subscriber’s branch is energized from a corresponding receiver
  • possibility of feeding the low-noise converters via a terminal multiswitch MS1752
  • terrestrial TV passive path allows reception of terrestrial programs without an STV receiver switching-on
  • depending on quality of the cable used for interstage coupling, cascading of up to 5 multiswitches  without the use of a compensating amplifier is available
  • suitable for return channel usage
  • high decoupling between the outputs
  • recommended power supply - SA125A-1913G-S(F)
