A band (NATO)
Range of radio frequencies
From Wikipedia, the free encyclopedia
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.

Military usage
The A band is used for long-distance HF radio communication, tactical UHF radio communication, and aeronautical mobile service.
