What frequency range is classified as High Frequency (HF)?

Explanation:
High Frequency is defined as roughly 3 to 30 megahertz. This band behaves uniquely because radio waves in this range can reflect off the ionosphere, allowing long-distance, worldwide communication beyond the line of sight. The other ranges fall into the VHF, UHF, and SHF bands, respectively, so they are not HF.
