C band
C-Band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 3.7 to 4.2 GHz. C-Band is primarily used for open satellite communications, whether for full-time satellite TV networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct broadcast satellite, which is a completely closed system used to deliver subscription programming to small satellite dishes connected to proprietary receiving equipment.
C-Band is highly associated with TVRO satellite reception systems, commonly called "big dish" systems since small receiving antennas are not optimal for C-Band systems. Typical antenna sizes on C-Band capable systems ranges from 7.5 to 12 feet (2.5 to 3.5 meters) on consumer satellite dishes, although larger ones also can be used.
Contrary to popular belief, digital C-Band does in fact exist.
