C-band

C-band refers to the portion of the electromagnetic spectrum allotted for satellite transmissions in the 4GHz to 8GHz frequency range. C-band satellite antennas are used frequently in areas of the world where signals can become degraded due to heavy rain or other intense climate-related conditions. As a rule, C-band satellite antennas range in size from 1.8 meters to 2.4 meters. C-band satellite communications suffer less from rain attenuation, but they require larger antennas and typically are used in Asia, Africa and Latin America. See also antenna, frequency bands, Ka-band, Ku-band and satellite dish.
