Definition
The radio frequency band from 30 to 300 megahertz (MHz). In aviation, VHF is the primary band used for civil air-to-ground voice communications (118.000–136.975 MHz) and for navigation aids such as VOR and ILS localizers.
Plain English
A specific range of radio frequencies that aircraft use for talking to controllers and for many navigation signals. It is the everyday radio band pilots tune on the comm radio.
Context Anchor
Pilots encounter VHF when selecting aircraft radio frequencies for air traffic control, airport advisory calls, and certain navigation receivers.
Derivation
Named simply by where it sits on the radio spectrum. 'Very high' is relative to the older, lower bands (LF, MF, HF) used in early radio. It does not mean the frequency is extreme — just higher than what came before.
Why Pilots Care
VHF provides the primary, reliable voice link for clearances, traffic advisories, and weather information during normal flight operations.
Intuition Check
VHF does not mean the radio volume is high or the transmitter is especially powerful. It means the radio waves are in a specific frequency range used by aviation radios.
Example Sentence 1
Tune the VHF comm radio to 121.5 to monitor the emergency frequency.
Example Sentence 2
ATC cleared the flight to change to a new VHF frequency of 128.75 for the next sector.
