Ku-band (Kurtz-under Band)

Frequency range allocated from 10.9GHz to 17GHz. Ku-band satellites are among the most numerous, operating for all forms of satellite communications, including video, voice and data services for consumers and enterprises. Most VSATs are in the Ku-band and are predominantly GEO-based systems. Ku-band satellite antennas (which are smaller than C-band antennas but suffer from rain fade in monsoon-like downpours) are typically used in Europe and North America. Bidirectional/interactive Ku-band antenna sizes range from 75 centimeters to 1.8 meters. See also Ka-band, L-band and S-band.
