Wikipedia
High frequency
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). 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 and for mountainous terrains which prevent line-of-sight communications. The band is used by international shortwave broadcasting stations (3.95–25.82 MHz), aviation communication, government time stations, weather stations, amateur radio and citizens band services, among other uses.

Examples of High Frequency in a Sentence
Juno's microwave radiometer probes deep into the planet's atmosphere by detecting high-frequency radio waves that can penetrate through the thick cloud layers. The data from Hubble and Gemini can tell us how thick the clouds are and how deep we are seeing into the clouds.
SpinLaunch fills this gap by providing dedicated orbital launch with high frequency at a magnitude lower cost than any current niche launch system, this will truly be a disruptive enabler for the emerging commercial space industry. There is a promising market surge in the demand for LEO constellations of inexpensive small satellites for disaster monitoring, weather, reconnaissance, communications and other services.
We are very excited about this discovery. This is the first time anyone has discovered planets outside our galaxy, these small planets are the best candidate for the signature we observed in this study using the microlensing technique. We analyzed the high frequency of the signature by modeling the data to determine the mass.
This will ensure that these (high frequency traders) can be held responsible for any potential misconduct.
