6-millimeter band

The 6 millimeter or 47 GHz band is a portion of the EHF (microwave) radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The amateur radio and amateur satellite band is between 47.0 GHz and 47.2 GHz, and the allocation is the same in all three ITU regions.[1]
