The LNB is the part on a satellite television dish that is installed at the end of the small, straight arm. “LNB” stands for “low noise block-down” converter, and is often referred to as the “eyes” on the dish. This electronic device receives the digital signal from satellites and begins the process of converting the digital signal into television broadcasting that your TV recognizes. The LNB and dish must be perfectly focused on the satellites, and are adjusted by setting the skew, elevation and azimuth of the dish. Writer Bio
