中文百科

高频

高频（英语：High frequency）是指频带由3MHz到30MHz的无线电波。比HF频率略低的是中频（MF），比HF频率略高的是甚高频（VHF）。

HF多数是用作民用电台广播及短波广播。其对于电子仪器所发出的电波抵抗力较弱，因此经常受到干扰。

High frequency 高频

HF's position in the electromagnetic spectrum.

An amateur radio station incorporating two HF transceivers.
A typical Yagi antenna used by a Canadian radio amateur for long distance communication

High frequency (HF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) between 3 and 30 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 metres). Frequencies immediately below HF are denoted medium frequency (MF), while the next band of higher frequencies is known as the very high frequency (VHF) band. The HF band is a major part of the shortwave band of frequencies, so communication at these frequencies is often called shortwave radio. Because radio waves in this band can be reflected back to Earth by the ionosphere layer in the atmosphere – a method known as "skip" or "skywave" propagation – these frequencies are suitable for long-distance communication across intercontinental distances. The band is used by international shortwave broadcasting stations (2.310 - 25.820 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services, among other uses.
