The VHF spectrum refers to the very high frequency range of radio waves, typically spanning from 30 megahertz (MHz) to 300 MHz. This portion of the electromagnetic spectrum is utilized for a wide array of communication and broadcasting applications due to its favorable propagation characteristics. VHF waves can travel longer distances than higher frequency waves and are less susceptible to interference from atmospheric conditions.

Key uses of the VHF spectrum include terrestrial broadcasting for television and radio, particularly FM radio. It is also crucial for aviation communication, allowing aircraft to communicate with air traffic control and other aircraft. Marine radio services, such as ship-to-shore communication and distress calls, also operate within the VHF bands. Amateur radio operators utilize parts of the VHF spectrum for their hobby, enabling long-distance communication under certain conditions. Furthermore, VHF frequencies are employed in land mobile radio systems for public safety, businesses, and other services requiring reliable two-way communication. The relatively wide bandwidths available in the VHF spectrum allow for efficient transmission of voice and data.
