VHFkanaal

VHFkanaal refers to a very high frequency radio channel. These channels operate in the frequency range of 30 MHz to 300 MHz and are commonly used for a variety of communication purposes. In maritime contexts, VHF channels are essential for ship-to-ship and ship-to-shore communication. They are used for distress calls, safety messages, and routine operational communication. Each VHF channel is assigned a specific purpose, such as Channel 16 for distress and calling, and other channels for navigation, weather, or port operations.

Beyond maritime use, VHF frequencies are also utilized for broadcasting radio and television signals, although with the advent of digital broadcasting, this is becoming less prevalent for traditional television. In aviation, VHF is used for air traffic control communications between aircraft and ground stations. Public safety agencies, such as police and fire departments, also employ VHF radio systems for their operational needs, allowing for communication over relatively short to medium distances. The propagation characteristics of VHF waves mean they tend to travel in straight lines, which is advantageous for line-of-sight communications but can be a limitation for long-distance transmission, as they do not follow the curvature of the Earth as effectively as lower frequencies. The availability and regulation of VHF channels are managed by national telecommunications authorities.
