VHF radio frequencies, which range from 30 MHz to 300 MHz, are particularly well-suited for line-of-sight communication, making them ideal for applications where reliable communication is crucial within a specific distance. A significant common use of VHF frequencies is in marine communication and aviation. In maritime settings, VHF radios are widely employed by ships to communicate with each other and shore stations, ensuring safety and coordination during navigation. Likewise, in aviation, VHF frequencies are essential for air traffic control communications, allowing pilots and air traffic controllers to maintain clear and efficient communication.

The characteristics of VHF frequencies, such as their ability to provide relatively stable propagation over moderate distances while maintaining clarity in voice communication, further enhance their suitability for these critical domains. This reliable communication is pivotal for both safety and operational efficiency, emphasizing the importance of VHF in these sectors.
