Which frequency range is typically used for VHF communication?

• A. 30 MHz to 300 MHz
• B. 300 MHz to 3 GHz
• C. 1 MHz to 30 MHz
• D. 10 GHz to 30 GHz

Answer: (A)

The frequency range typically used for VHF (Very High Frequency) communication is from 30 MHz to 300 MHz. This band is critical for FM radio broadcasting, television broadcasts, and marine communication, among other applications. VHF frequencies are characterized by their ability to travel long distances and penetrate various types of terrain, making them suitable for a wide array of communication needs, especially in maritime and aviation fields. Frequencies within this range are advantageous for line-of-sight communications and are less prone to interference from atmospheric noise compared to lower frequencies.
