What Are The Benefits of Having 2 LNBs on Your Satellite Dish?

19 February 2014  |  Ashley

The humble low-noise block downconverter (commonly known as the LNB) is one of the most vital parts of any satellite dish configuration. Most satellite dishes will only have one LNB, but it is now becoming more and more common for a multi-LNB configuration. If having more channels available on demand is what you’re looking for, a 2 LNB setup might be what you’re looking for.


So What Benefits Do You Get With a Multi-LNB Setup?


If you’re somewhat of a novice when it comes to satellite dish setup, it may be helpful to clarify some of the jargon surrounding the topic. The function of an LNB is to collect the microwave signal from a satellite reflected onto it from the dish, amplify the signal, downconvert the signal to an intermediate frequency and then send it on its way down a coaxial cable to your set-top box. This, however, gives rise to the major limitation of the LNB; satellite dishes have to be exactly positioned to receive a signal, so can only receive signals from one satellite at a time. This can be overcome using a motorised satellite dish that can point anywhere in the sky, but many people find this to be a hassle to set up. What’s more, if you want to view a channel being broadcast on another satellite you have to wait for the dish to re-orient itself. A multi-LNB setup is the solution to this.

With 2 LNBs, you’ll be able to receive signals from 2 satellites simultaneously without having to wait for any re-orientation when you switch between the two. This is a huge benefit, and a big plus for lots of home satellite enthusiasts. The only caveat is that the satellites have to be quite close together – generally within 6° of each other. This can limit your choice, but there are satellite pairs (such as Astra 19.2°E and Hot Bird 13°E) that are amenable.


Consider a Monoblock Setup


A monoblock setup consists of 2 LNBs within a single casing, and negates the need for fiddly additions to your dish. These are generally a better fit than 2 separate LNBs and fit the majority of dishes. If you don’t want the hassle of installing another LNB, then this is definitely the choice for you.
