WebKnown as the decameter band or decameter wave, high frequency (HF) is the ITU designation [1] for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz). The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio.
