VHF Band

The IEEE VHF band, or Very High Frequency band, encompasses the frequency range from 30 MHz to 300 MHz. This segment of the radio spectrum is utilised for a variety of communication services. In Australia, the VHF band is commonly employed for television broadcasting, FMFM: Frequency Modulation (FM) is a method of encoding information in a carrier wave by varying its frequency. Unlike Amplitude Modulation (AM), which varies the amplitude of the carrier wave, FM changes the frequency to transmit data. This modulation technique is particularly effective in reducing… radio, two-way land mobile radio systems, marine communications, and air traffic control. VHF signals are known for their ability to travel over long distances, especially over water and open terrain, making them ideal for maritime and aviation purposes. However, they are generally limited to line-of-sight propagation, meaning that they may be obstructed by buildings, hills, and other large obstacles. The VHF band is divided into different sub-bands, each allocated for specific types of services. For instance, the FM radio band occupies the frequencies from 88 MHz to 108 MHz, while television channels are spread across various segments within the VHF range.
