This document provides a chart of radio frequency allocations in the United States. It lists frequency bands from 3 kHz to 30 GHz on the x-axis and various radio services on the y-axis. Color coding indicates allocations as non-government exclusive, government/non-government shared, or government exclusive use. Frequency bands are allocated for services including broadcasting, mobile services, radionavigation, radiolocation, amateur radio, and space research.

This chart is a graphic single-point-in-time portrayal of the Table of Frequency Allocations used by the
FCC and NTIA. As such, it does not completely reflect all aspects, i.e., footnotes and recent changes
made to the Table of Frequency Allocations. Therefore, for complete information, users should consult the
Table to determine the current status of U.S. allocations.
