H band
H band can refer to two different regions of the electromagnetic spectrum, in the radio and near-infrared. ==Radio== The NATO H band is the range of radio frequencies from 6 GHz to 8 GHz in the system of letter designations for frequency bands used by NATO for electronic countermeasure (ECM) applications. This is equivalent to wavelengths between 5 cm and 3.75 cm. It is a subset of the SHF band as defined by the ITU and corresponds to the upper half of the C band (4–8 GHz) as defined by the IEEE.
