The larger the dish the more it magnifies the satellite signal. Therefore reception of the weak signals requires relatively bigger diameters of the dish. For instance, the weakness of Spot 3 of Intelsat 707 in Europe makes it necessary to use the 3-meters dish for the reception of Israeli Channels in Austria. Each has some advantages and dis-advantages. Dish Mount is an important component of the satellite system.
Basic system contains a fixed-dish which is targeted for reception of a single satellite.
More advanced systems are based upon various types of mounts, when the rotating dish is aimed at several particular satellites with the help of an indoor unit called Positioner . There are different types of the mounts available on the market. Most of these mounts are not capable of tracking the big variety of the satellites.
