Satellite Installation

mini_dish_2A satellite dish, like an aerial is designed to receive signals from a specific transmitting source, in this case a satellite in orbit around the earth. These are fixed to the outside of buildings and come in many sizes, from the mini dish seen on most private homes to the larger dishes for foreign or European broadcasts; these are sometimes motorised to track particular satellites.

Whatever the size, a standard dish consists of a parabolic (bowl-shaped) surface and a central feed horn.  The curved dish focuses incoming radio waves onto the feed horn, which passes the signal onto the receiving equipment. In order to receive a good quality signal, it is important that there no obstacles between the satellite and the dish, especially when some systems require signals from two or more satellites simultaneously.
