Lühilaineds, also known as shortwave radio, refers to the portion of the radio spectrum that falls between 3 MHz and 30 MHz, corresponding to wavelengths between 10 meters and 1 meter. This frequency range is particularly useful for long-distance communication, as it can propagate over the horizon and even reflect off the ionosphere, allowing signals to travel around the curvature of the Earth. Shortwave radio is widely used for international broadcasting, amateur radio, and military communications. It is known for its ability to provide reliable communication over vast distances, making it a valuable tool for global news dissemination, emergency services, and scientific research. However, shortwave signals can be affected by atmospheric conditions and solar activity, which can cause signal fading and interference. Despite these challenges, shortwave radio remains a vital means of communication in various fields.
