Benefits:

  • The cascadable distribution system for signals of 4 satellite-based polarizations and of terrestrial TV for floor-by-floor
  • wiring layout or for construction of a Y-network;.
  • A possibility of power supply to low-noise converters through terminal multiswitches MS554, MS54P;
  • Effective use of power supplies: multiswitches do not consume current from the trunk;
  • The subscriber’s branch is fed from a corresponding receiver;
  • For ease of level equalization in the distribution network, there are provided two types of multiswitches  with different          tapping factors;
  • The passive route of terrestrial TV allows for reception of terrestrial programs without a CCTV receiver  being turned on;
  • Depending on quality of a cable used for interstage connections, up to 5 multiswitches may be cascaded without a trunk
  • amplifier;
  • Suitable for using a feedback channel.

MS553

  • A transit 5×4 multiswitch.

MS554

  • A terminal 5×4 multiswitch;
  • A possibility of power supply upward.

MS554P

  • A terminal 5×4 multiswitch;
  • Generates 14V IF for power supply through lines of V polarization;
  • 18V IF is supplied through lines of H polarization.
