Five or more Sky digital receivers
The dish set up is the same as using a Quad LNB, however for 5 or more receivers a Quattro LNB needs to be used. The Quattro LNB's have 4 outputs but each output only receives one part of the 4 wavebands broadcast: High band V, High band H, Low band V, Low band H. Each individual part is carried along the 4 satellite cables and inserted into a multiswitch box, the inputs on the box are marked: High V, High H, Low V, Low H. The multiswitch box which has many outputs is designed to combine the 4 signal parts and allow the full signal to be sent to any number of satellite receivers. The Multiswitch boxes are sold with 5 inputs to allow for the insertion of a terrestrial TV signal if required. Once the signals have been combined in the Multiswitch box, only one CT100 cable is required from the Multiswitch box down to the Satellite receiver, this lead can carry the Satellite signals and the Terrestrial TV plus FM or DAB radio signals if required. If also combining TV / FM etc, a surface plate will need to be fitted at the main TV point to separate the Satellite / TV / FM or DAB signals in order that the appropriate appliances can be plugged in.
