The only difference with the dish is the lnb, it is wideband. The 2 connectors are for Vertical and Horizontal polarisations. Previous lnbs use standard voltage and pulse switched bands and polarisation methods
To use the 28.2 deg East satellite for both SkyQ AND a feed to your non-uk satellite receiver, there is the legacy Q lnb
The nearest outputs are for Sky Q receivers and have Vert and Hor channels separated. Note: the Sky receiver checks the cables and auto selects the polarity, so it is not necessary to have the cables the ‘right’ way round.
The 4 sockets at the back are the more familiar standard lnb outputs, these you can connect to a Sky, Sky+ or any standard satellite receiver – currently any non-uk receiver, for example French TNT or German receivers. To enable switching between the 2 services UK and German for example , a diseqc switch is used.
Before you ask….
The standard Sky dish is completely useless as a multi-satellite dish. It is just too small and there are no suitable LNB adaptors available even if it was big enough.
The Triax and Technomate dishes have versatile and accurate LNB adaptors which will give a good signal with some tolerance for bad weather for the SkyQ + French or German reception and many others.
