What is look angle of antenna?

The look angle of an antenna refers to the angle between the horizontal plane and the line of sight to the satellite or target being communicated with. It is typically measured in degrees and can be divided into two components: the elevation angle, which indicates how high above the horizon the antenna must be pointed, and the azimuth angle, which specifies the compass direction. Look angles are crucial for optimizing signal strength and ensuring effective communication links, especially in satellite and terrestrial radio systems.
