What does VHF stand for in radio communications?

Explanation:
VHF stands for Very High Frequency. This term names a portion of the radio spectrum from about 30 to 300 MHz. Signals in this band travel primarily by line of sight, making them reliable for short- to medium-range communications like aviation voice radios. In aviation, VHF radios typically operate around 118 to 137 MHz and use frequency modulation for clear, static-resistant transmission. The other terms—velocity, vertical stability, and Venturi tube—aren’t related to radio frequency terminology.
