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]

THF Sub-mm Some administrations have authorized spectrum for amateur use in this region.

1 This is not mentioned in the ITU's Table of Frequency Allocations, but individual administrations may make allocations under Article 4.4 of the ITU Radio Regulations. See the appropriate Wiki page for further information.
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. These allocations may only apply to a group of countries.
