Cascaded multi-switches MS1351, MS1352

1
Manufacturer:
System:
type of equipment:

  

Extras:

  • - cascaded signals distribution system  of 12 satellite polarizations and terrestrial TV for floor-by-floor distribution or for building the network according to “star” scheme;
  • - efficient use of power sources: multi-switches do not consume any current from the trunk;
  • - subscriber branch is powered by an appropriate receiver;
  • - possibility of power supply to the low-noise converters via terminal multi-switch MS1352;
  • - passive path of terrestrial TV allows the reception of terrestrial programmes without turning on the CTB receiver;
  • - depending on the quality of cable used for interstage connection, it is possible to cascade up to 5 multi-switches without using compensating amplifier;
  • - applicable for the use of reverse channel;
  • - high reverse isolation between the outputs;
  • - recommended power supply source - SA125A-1913G-S(F);
