A band (NATO)

For other uses, see A band.

NATO A band

Frequency range	0 to 250 MHz
Wavelength range	≥ 1.2 m

The NATO A band is the obsolete designation given to the radio frequencies from 0 to 250 MHz (equivalent to wavelengths from 1.2 m upwards) during the cold war period. Since 1992, frequency allocations, allotment and assignments are in line with the NATO Joint Civil/Military Frequency Agreement.^[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.
