HF Operations
HF Operations, or High Frequency Operations, refer to the use of high-frequency radio waves to communicate over long distances. These operations leverage HF radio bands, typically from 3 to 30 MHz, which can skip off atmospheric layers, enabling signals to reach far-off places. HF is essential for maritime, aviation, and military communications, as it allows for reliable contact without relying on satellites or cellular networks. Operators must understand factors like signal propagation, antenna design, and atmospheric conditions to effectively use HF systems, ensuring connectivity in remote or emergency situations.
