SAT IF

For 4 ... 16 SAT IF signals.

The UniSystem multiswitches can be used as stand-alone

device or can be cascaded with themselves for an easy

extension of the number of subscribers. The UniSystem is

extendable to up to 16 SAT IF levels.

SAT IF:

• AftertheSATsignalhasbeendecoupledby

microstripline directional couplers, it is amplified for

each receiver output, which produces a tap gain

of -4 ... 2 dB. (SMS 5547 UI)

In addition to the wall mounting frame, the

„piggyback“ assembly also includes an adapter frame

3. The master outputs also facilitate cascading, so that

the number of receivers can be increased. Without

amplifying the signal, it is possible (depending on

cable quality and length) to feed up to 24 receiver
