Home > Library > Miscellaneous > Wikipedia

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]

¹ This is not mentioned in the ITU's Table of Frequency Allocations, but it is a de facto international amateur radio allocation. ² HF allocation created at the 1979 World Administrative Radio Conference. These are commonly called the "WARC bands". ³ This includes a currently active footnote allocation mentioned in the ITU's Table of Frequency Allocations.
