How does the sat switches work?

[skype]

I wonder how do the sat switches work.What I want to know especially is, in our apartment I have seen a quad lnb connected to a sat switch.And from the sat switch all the habitants can watch from the sat.

As I guess, there are 4 bands for a universal LNB.So is this the reason why quad lnb is enough to distribute the signal from a sat? so that 4 independant outputs from the quad lnb swithes for 4 different bands.

I hope I was clear enough.

Re: How does the sat switches work?

Is it a Quad lnb or a Quattro lnb? They are not the same.

After your explanation, I think that the lnb is most probably quattro LNB with hardcoded bands.Thanks for the link.

Re: How does the sat switches work?

there are two bands. upper band and lower band. and there are two polarisation, vertical and horisontal. so there must be four different lnb output.
1.output-->lowerband-vertical
2.output-->lowerband-H
3.outout-->highband-V
4.output-->highband-H

Re: How does the sat switches work?

A Quattro LNB is designed for use in buildings where there are different users of satellite like a block of flats. The Quattro LNB is then joined to a multi switch to supply different apartments or flats with a cable or cables to their receivers. A multi switch allows many people to use the Quattro LNB as if they each had their own LNB Quad. A Quattro LNB will feed many more than four receivers via the multi switch

A Quad LNB on the other hand is normally used by one household and this supplies four separate cables with an equal strength signal that can be sent to various rooms in the house or flat. People use satellite dish Quad LNB’s if they need at least four feeds to their dwelling. The way these are used can be many fold.
