Propagation Characteristics of Ultrashort Wave

Time：2020-05-19

Compared with other communication modes, ultrashort wave communication has its remarkable characteristics. Ultrashort wave communication uses line-of-sight propagation mode, which is more stable than short-wave skywave propagation mode, and is affected by seasonal and diurnal changes. Small antennas can be used as directional antennas with small size, simple structure and high gain. In this way, the smaller the available power of the transmitter frequency is higher, the frequency band is wider, can be used for multi-channel communication modulation mode is usually FM, can get a higher signal-to-noise ratio. Communication quality is better than short wave.
