I have been currently working on pumping Sky HD around the new house build.

Installation of 60" Satalite Dish
Freeview Digital Arial
Quattro LNB
24 port Multi Switch
24 port 1GIG Network switch


I have run WF100 shotgun cable into every room along with 2 Cat 6 cables. This should feed the whole house and stream HD content, Intenet TV etc.. from the Homeserver currently sitting at 12TB in storage.

All this cabling leads back to the study where I will install a 19" rack comms cabinet.

Study just plastered...and just need to test it.:)

I ran 2 WF100 shotgun cables to the Loft along with 2 x earth wires...one from the dish and one to the Electric Junction Box..The system will run 12 x Sky HD + boxes or 24 standard Sky boxes

Do you not need to have an LNB feed for every connection required? I take it there is some fancy pants way of splitting the feed?

The Quattro LNB is mouted to the dish...The signal is split into 4 from the roof and fed into the multiswitch.

Look at the pic the 4 cables going into the top of the switch is the split Satalite Signal

The 5th cable is the Freeview HD signal and the last one not connected is for a DAB arial if I decide to fit one

The multi-switch is the "fancy pants" way of splitting the feed. It works on conjunction with the Quattro LNB. This is different in one important aspect from the standard Quad LNB fitted to most Sky satellite dishes.

A standard LNB is driven from the satellite receiver to change between 4 states depending on the signal to be received. The box does this as you change channel. That's the reason why you can't split a satellite feed in the same way you can an aerial signal. A Quad LNB is simply 4 LNBs in a single body. Each LNB is switchable between the 4 states.

A Quattro LNB isn't switchable. It has 4 LNBs, but each one is fixed to one each of the single states. When the Satellite receiver calls for one of the 4 states it's the multi-switch that routes the correct signal from the appropriate LNB to the Satellite receiver. The multi-switch also distributes the LNB signals. So if there were 24 calls all for one state then the switch sends out 24 lots of the same LNB signal. It's the same principle as a matrix switch.
