VHFradioviestintä

VHFradioviestintä refers to radio communication utilizing frequencies within the Very High Frequency (VHF) band. This band typically spans from 30 MHz to 300 MHz and is commonly employed for short to medium-range terrestrial communications. In Finland, the term VHFradioviestintä is frequently associated with maritime and aeronautical radio services, as well as amateur radio operations.

Maritime VHF radio is crucial for safety and communication at sea, allowing vessels to contact each other, shore stations, and emergency services. These systems operate on specific channels designated for various purposes, such as distress calls, calling, and inter-ship communication. Similarly, aviation utilizes VHF for air traffic control, pilot-to-pilot communication, and communication with ground services.

Amateur radio operators, often referred to as "ham radio," also extensively use the VHF band for local and regional contacts. This hobby allows enthusiasts to communicate with others around the world, often through repeaters that extend the range of their transmissions. The propagation characteristics of VHF frequencies, such as line-of-sight limitations, influence the effective range of VHFradioviestintä, making it suitable for applications where direct contact over moderate distances is sufficient.
