With the popularity of Freesat, it is becoming harder and harder to manage with a single LNB(or Low Noise Block Converter). Usually, a standard satellite dish installation comes with a single LNB. This means that you can only watch one channel or record one channel but not do both at the same time. You could opt to have a dual LNB which will solve this problem. But what about Granny’s telly in the bedroom or little Timmy’s or the second telly in your bedroom? Nowadays a one telly house is a rarity. So if you want to record programs in the lounge and also have a telly elsewhere in the house you will need a Quad LNB.
What Is A Quad LNB
A low noise block (LNB) converter is the receiving part of your satellite dish. It takes the weak signal that is transmitted from the satellite, makes it stronger and converts it to something that will be understood by your satellite receiver box. A quad LNB can send the signal to four separate receiver boxes allowing each to be operated independently.
who exactly needs an LNB quad
l Anyone with Freesat or Sky who wants to record one channel while watching another and has more than one television in the house.
l Anyone who plans to add an extra telly for viewing Sky or Freesat in the future.
l Anyone currently limited to analogue or Freeview TV and wants the ability to upgrade to Sky or Freesat which opens up the wonderful world of watching and recording High Definition TV.
l Basically anyone who decides that satellite is the way forward. Single and dual LNB’s are in the past. For very little extra money you can have the extra feeds the satellite dish Quad LNB gives you.
How to Choose a Quad Satellite LNB
There are some factors to be considered when you purchase a quad LNB. First, decibel rating: Generally however the rule is the lower the better. The lowest I have come across on the internet is 0.1db however these do tend to be a little pricier at over $50. Secondly, Weatherproofing, Most but not all come with a snap out cover which protects the connectors from rain and frost etc… If you do decide to go cheap make sure you take steps to protect the connections at the dish as the weather will cause wear and tear and subsequent signal loss if these are left unprotected. Third, Quality & Price, Anywhere between $10 and $250. At the top end of the price scale any value added would only be appreciated by the purest of techno files or those with receivers on the very fringe of the reception who need to seek out every last drop of signal available to them. You can purchase the cheap LNB via internet. Some online stores will offer high quality and reasonable price.
