A LNB stands for Low Noise Block and is the part that points at the satellite dish. It is the most important part of a satellite dish installation as this is what captures your signal for your viewing.
There are several brands out in the market and if you do choose a LNB make sure that it is a good quality LNB as this will make the difference between you being able to watch your service in the rain or not being able to.
At IMC we have our own range of 11300LO, LNB’s that we have designed. They have been deigned for great signal reception and durability. They outperform most of other LNB’s on the market. C band LNB’s are a lot bigger and are specific to C band.
