TheNATOJ band is the designation given to theradio frequencies from 10 to 20GHz (equivalent towavelengths between 3 and 1.5 cm). Since 1992 frequency allocations, allotment and assignments are in line toNATO Joint Civil/Military Frequency Agreement (NJFA).^[1]However, in order to identify military radio spectrum requirements, e.g. for crises management planning, training,Electronic warfare activities, or in military operations, this system is still in use.
