Normally, if you own a satellite dish for use with your television, you will have a box that is either attached to or in the dish, which goes by the acronym LNB. These letters stand for “low noise block” and this is what enables your dish to accept the signal from the satellite, which is slightly weakened due to distance, and convert it into a stronger signal that basically gives you the opportunity to view what the satellite is programmed for, on a per “channel” basis. Many people become frustrated that this cannot be done with more than one television within a home, however there is now an alternative that offers the ability to use up to four televisions from the same satellite dish and it is not that costly – the quad LNB is here.
The “quad” part of this box, refers to the number of signals that it can provide; four. Each box, has a decibel rating and the lower the rating, the better the product. Prices range from $10-$250, so it is important to select a good box that will work for many years. Selecting a good box is not as easy as it seems, since there are not well-known companies selling them. There are known brands, and many are available through sites like Ebay and Amazon.
The best way to determine whether or not a quad LNB is ultimately the best for you, as well as what kind of box to purchase, is to go online and see what others are saying about them. People will normally discuss exactly what is on their minds, especially when it comes to having parted with good money for a device that should work. Beware of those who are just there to either promote or debunk a product, as well. Alternatively contact a satellite dish provider in your area to discuss the options.
