The Global SDS InLine AMP stacker allows 2 separate IF signals to be combined onto one satellite grade coaxial cable and separated at the end location by the de-stacker unit (maximum range of 30m).
2x LNB inputs into one cable
Both LNB inputs independently selectable by voltage/tone or DiSEqC 1.2 controls
DiSEqC loop through to LNB/multiswitch
Covers cable lengths up to 50m when used with SDS line amplifier (sold separately)
The SDS has been designed to allow two satellite signals to be fed down one coaxial cable before being returned to its original configuration to
feed two STB’s or a twin tuner satellite STB. Signals can be supplied by either a universal multi-port LNB or more typically from a multiswitch. By
allowing DiSEqC commands to pass through the “Stacker” it is possible to connect the unit to a DiSEqC multiswitch for operation on a 9 wire
Whilst the DiSEqC SDS can be used in DiSEqC applications, it can also be used in situations where DiSEqC is not present.
The SDS can be used for coaxial cable lengths up to 30 metres, however from 30 to 60 metres the SDS Line Amplifier must be fitted. Reliable
operation is determined by the position of the amplifier, quality of coaxial cable fitted and signal strength from LNB or multiswitch.
