How to Add an LNB to a Satellite Dish
Your satellite dish is made up of three basic pieces. The dish itself, the dish mount and the Low Noise Blocker (LNB). The LNB is the "antenna" part of your dish that receives the signal that your dish is gathering and sends it to your receiver. If your LNB doesn't work or needs to be upgraded, you don't have to switch out the entire dish, all you need to do is replace the LNB.
