Many people, even those who say they are experts, confuse a Quad LNB with a Quattro LNB.
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. I have heard numbers of feeds up to a hundred mentioned. These LNB’s are never, unless by mistake, used for single households. As Quattro LNBs tend to get ‘switched’ less often they usually have a longer lifespan than the Quad output LNB. If you share your building with many other tenants and subscribe to Sky or receive Freesat then you are likely to be feeding your satellite signal via a Quattro LNB. If your signal is not satisfactory via this system it is not advisable that you touch the satellite dish or LNB or you may find you and your fellow signal sharers end up with no signal at all. I would suggest you contact whoever installed the system and get them to check it out. If you are not sure who this is then perhaps you can contact the maintenance contractor.
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. There may be a main television which is connected to a receiver which can record while watching live television in which case this will take two of the cable feeds. There may be another television with the exact same setup or another two televisions which do not require a record and watch at the same time facility and therefore only require a single feed each.
For those who require more feeds and let’s face it this is becoming more and more frequent there is the giant amongst LNB’s – the Octo LNB which provides, as the name suggests, eight feeds.
