Switching units (multiswitches)

Cascadable TERRA multiswitches MS408

1
Manufacturer:
System:
type of equipment:

 

Benefits:

  • Transit of supply voltage from the receiver to trunk lines;
  • A cascadable distribution system for signals of 4 satellite-based polarizations for floor-by-floor wiring layout or
  • for Y-network arrangement;
  • Effective use of power supplies: multiswitches do not consume current from the trunk; the subscriber’s branch is fed from
  • For ease of level equalization in the distribution network, there are provided two types of multiswitches with different           tapping factors.
