Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter. Frequencies immediately below VHF are denoted high frequency (HF), and the next higher frequencies are known as ultra high frequency (UHF).

The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band. From low to high frequency these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and ...

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.
It uses frequencies in very high frequency (VHF) from 108 to 117.95 MHz. Developed in the USA in 1937, VOR is the standard air navigational system in the world, used by both commercial and general aviation. There are about 3000 VOR stations around the world.
Very high frequency (VHF) is an ITU designation of radio frequencies. The designation has all frequencies between 30 megahertz to 300 megahertz. Behind the VHF frequencies is called high frequency (HF). Above the VHF frequencies is called ultra high frequency (UHF). In many parts of the world, VHF Band I was used for the broadcasting of analog ...
Very High Frequency. Very high frequencies (i.e., above 30MHz) are mostly line-of-sight waves, and above 3GHz, atmospheric and precipitation scattering and absorption become significant.

Very high frequency (VHF) is the radio frequency range from 30 MHz to 300 MHz. It is also known as the meter band or meter wave as the wavelengths range from ten to one meters. Frequencies immediately below VHF are denoted HF, and the next higher frequencies are known as Ultra high frequency (UHF).
