What is dish network?

In 1999, EchoStar obtained the broadcasting assets of a failed joint venture between ASkyB and MCI Worldcom including 28 transponders at the 110°W orbital location. Since EchoStar also owned the adjacent 119°W orbital location it developed the DISH 500 to receive the signals of both orbital locations using one dish and an innovative dual-LNB assembly. DISH Network originally used an 18-inch satellite dish called DISH 300 that allowed subscribers to receive a signal from one satellite location. Today, DISH Network commonly uses 20-inch satellite dishes called DISH 500, which allows subscribers to receive satellite signals from two satellite locations (119°W and 110°W) simultaneously. Slightly larger dishes such as the 36 inches × 20 inches SuperDISH, DISH 1000, and DISH 500+ are capable of receiving satellite signals from three satellite locations simultaneously, and the advanced DISH 1000+ system receives signals from four locations. DISH 500+ and 1000+ are becoming more common as DISH Network (as well as other DBS services) are attempting to squeeze more programming onto their growing systems, particularly local and national American television network stations, as well as HDTV and ethnic programming.
