Some administrations have authorized spectrum for amateur use in this region;
others have declined to regulate frequencies above 300 GHz.

All allocations are subject to variation by country. For simplicity, only common allocations found internationally are listed. See a band's article for specifics.

|
HF allocation created at the 1979 World Administrative Radio Conference. These are commonly called the "WARC bands".
|
| [t3]
|
This is not mentioned in the ITU's Table of Frequency Allocations, but many individual administrations have commonly adopted this allocation under "Article 4.4".
|
| [t4]
|
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.
