ultrakortvågsbandet

The ultrakortvågsbandet, often abbreviated as UKV, refers to a segment of the radio frequency spectrum. This band typically encompasses frequencies from 30 MHz to 300 MHz. Its designation as "ultra short wave" is a historical one, reflecting its shorter wavelengths compared to earlier radio technologies. The UKV band is characterized by its ability to carry a large amount of information and its relatively line-of-sight propagation. This means that transmission and reception are often limited by the curvature of the Earth and obstructions, requiring repeaters for long-distance communication.

Within the UKV band, several important applications are found. One of the most prominent is the broadcasting of FM radio. The high frequencies allow for wider bandwidths, enabling stereo sound and better audio quality than AM broadcasting. Television broadcasting also historically utilized parts of this band, though newer digital television standards have shifted these frequencies. Additionally, the UKV band is crucial for various mobile communication services, including walkie-talkies, amateur radio, and some public safety communications. The characteristics of the UKV band make it suitable for short to medium-range communication systems where reliable signal transmission is needed. Its allocation and regulation are managed by international bodies like the International Telecommunication Union (ITU) to prevent interference between different services.
