A satellite dish is a type of parabolic reflectorantenna designed with the specific purpose of transmitting signals to and/or receiving from satellites. A satellite dish is a particular type of microwave antenna. Satellite dishes come in varying sizes and designs, and are most commonly used to receive satellite television.
Modern dishes intended for home television use are generally 45.72 centimeter (18") in diameter, and are fixed in one position. This type of system is referred to as direct broadcast satellite or DBS. Systems commonly used with communications satellites for Ku bandfree-to-air and ethnicbroadcast reception use a slightly larger antenna, typically about one metre in size. Older types of home satellite dishes, called television receive-only or TVRO, were several feet in diameter and had motors which could position the dish to receive signals from several different satellites.
DTH operating on Ku band which the government has recently allowed, needs only a small dish (1 or 2 feet) in diameter which can be easily installed on roof top or a window of the subscriber's home.
DTH can be a very good platform to deliver latest Hindi, English and regional songs, news and other features in digital, stereo mode to their subscribers.
DTH scores over CAS in enabling the consumers to be exposed to a variety of new channels introduced by the DTH service provider, which would be a part of the basket offering.
