VHF, or Very High Frequency, communication typically operates within the frequency range of 30 MHz to 300 MHz. This range is well-established and utilized for various types of communication, including FM radio broadcasting, television broadcasts, and two-way radio systems.

The significance of this frequency range lies in its ability to provide reliable communication over moderate distances, as the propagation characteristics of VHF frequencies allow signals to travel further than those at lower frequencies. Additionally, VHF is less affected by atmospheric noise compared to lower frequency bands, making it advantageous for clear audio transmission.

Understanding the VHF range is crucial for anyone involved in radio communication, as it encompasses important applications in aviation, maritime, and public safety communications, among others. This range enables effective line-of-sight communications, which is vital in many operational contexts.
