Full Form of VHF
What is VHF?
VHF refers to the radio frequency range from 30 MHz to 300 MHz. It is widely used in India for FM radio broadcasting (88-108 MHz), television broadcasting, aviation communication, marine communication, and two-way radio systems used by police, ambulances, and emergency services. The Indian Air Force, Navy, and Coast Guard rely heavily on VHF for short-range tactical communication. In India, All India Radio uses VHF for transmitting FM services, and the Department of Telecommunications regulates these frequencies. VHF waves travel in straight lines and are ideal for line-of-sight communication, which makes them suitable for broadcasting in relatively flat terrains. They are also used in land mobile radio systems, walkie-talkies, and amateur radio operations, with the latter being regulated by the Wireless Planning and Coordination Wing. VHF is preferred for short-range communication because its signals are less affected by atmospheric interference compared to lower frequency bands. However, buildings, hills, and other obstacles can block VHF signals, which is why transmitter towers are placed at elevated locations across Indian cities and highways. For students preparing for competitive exams like UPSC, SSC, and technical recruitment tests, VHF is a frequently asked topic in physics and telecommunications sections.
