The NATO B band is the range of radio frequencies from 250 MHz to 500 MHz in the system of letter designations for frequency bands used by NATO for electronic countermeasure (ECM) applications.[1][2] This is equivalent to wavelengths between 1.2 m and 0.6 m. The B band is in the VHF / UHF range of the radio spectrum as defined by the ITU and the IEEE.[3][4]

The B band overlaps with the P band of the older IEEE classification system.[citation needed]
