FAST has a 500 m (1,640 ft) diameter dish constructed in a natural depression in the landscape. It is the world's largest filled-aperture radio telescope [2] and the second-largest single-dish aperture, after the sparsely-filled RATAN-600 in Russia. [3] [4]
It was retroactively named the "DISH 300" when legal and satellite problems forced delays of the forthcoming DISH 500 systems. It uses one LNB to obtain signals from the 119°W orbital location, [ 85 ] and was commonly used as a second dish to receive additional high-definition or international programming from either the 148°W or 61.5°W ...

Early satellite television systems were not very popular due to their expense and large dish size. [68] The satellite television dishes of the systems in the late 1970s and early 1980s were 10 to 16 feet (3.0 to 4.9 m) in diameter, [ 69 ] made of fibreglass or solid aluminum or steel , [ 70 ] and in the United States cost more than $5,000 ...
The 500-meter-diameter (1,600 ft) dish with an area as large as 30 football fields is built into a natural karst depression in the landscape in Guizhou province and cannot move; the feed antenna is in a cabin suspended above the dish on cables. The active dish is composed of 4,450 moveable panels controlled by a computer.

The telescope's main collecting dish had the shape of a spherical cap 1,000 feet (305 m) in diameter with an 869-foot (265 m) radius of curvature, [9] and was constructed inside a karst sinkhole. [10] The dish surface was made of 38,778 perforated aluminum panels, each about 3 by 7 feet (1 by 2 m), supported by a mesh of steel cables. [9]
