Originally Answered: Why do we use high frequency waves as carrier waves? HF (2 – 30 MHz) is used for long distance communications because the atmosphere acts to bend these rays and bounce them back towards earth, so that they can travel all over the world, using very modest power to do so.

Like the LF band, the Medium Frequency (MF) band is also mostly used for AM radio broadcasting. The High Frequency (HF) band is most useful in shortwave radio applications, as well as aviation air-to-ground communications .
