The satellite multistacker is a standalone device that can be installed directly after a twin or quad universal vertical - horizontal LNBF. It is typically installed before the first distribution point in the SMATV system.
It combines 2 horizontal & 2 vertical satellite services from 2 orbital locations and combines them on a single RF cable so that a single RF input port on an IQ3 or later STB can receive the signals.
The Multistacker has 4 input ports which cater for low & high band signals.
Low band via DC Voltage.
High band via DC & 22 KHz tone.
From left to right
- Port 4 HH = 18 volts plus 22 KHz (future satellite)
- Port 3 VH = 13 volts plus 22 KHz (future satellite)
- Port 2 H L = 18 volts (Current Foxtel H pol services)
- Port 1 V L = 13 volts (Current Foxtel V pol services)
The multistacker has 2 ports on the bottom.
- Port 1 Stacked satellite output port with the option of line powering via a 12 volt DC power injector and power pack.
- Port 2 local powering via a 12volt DC power pack.
Due to the design of the multistacker there is no headend set up procedure, the Foxtel N.I.T (Network Information Table) is updated which informs the SMS what frequencies to tune to in the same way a FOXTEL STB is updated in the field. The installation method for a large variety of building has now become more simplified, such as;
- Domestic homes that are difficult to re-cable.
- MDU’s listed as “non-homes passed” which have been difficult to cable due to cabling access.
- MDU lite buildings that are H polarity only cabled.
- Twin backbone no PVR buildings with single laterals.
- Single wired Commercial Buildings.
- Single wired residential Estates including RF or Optical distribution.
- Frequency Range 950 - 2400 MHz
- 4 input ports
- Can be powered locally or line powered
- Built in AGC
- Typical output level is 85dB
