High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 megahertz (MHz) . It is also known as the decameter band or decameter wave as its wavelengths range from one to ten decameters (ten to one hundred meters).

Medium Frequency (MF): 300-3000 kHz Because medium frequencies afford stable transmission of radio waves over long distances, they are used primarily for medium wave broadcasting (AM radio), ship communications, LORAN (radio navigation), and other applications .

Medium Frequencies (MF) designated for marine communication range between 1605 kHz to 3800 kHz and are called “t” band. High Frequencies (HF) designated for marine communication range between 4000 kHz to 27500 kHz and are called “u” band.
