C band
Frequency range	500–1000 MHz
Wavelength range	60–30 cm
Related bands	UHF (ITU / IEEE)

The NATO C-band is the obsolete designation given to the radio frequencies from 500 to 1000 MHz (equivalent to wavelengths between 0.6 and 0.3 m) during the Cold War period. Since 1992, frequency allocations, allotment and assignments are in line with the NATO Joint Civil/Military Frequency Agreement (NJFA).^[1] However, in order to identify military radio spectrum requirements, e.g. for crisis management planning, training, electronic warfare activities, or in military operations, this system is still in use.
