(Summary description)Compared with other communication methods, ultrashort wave communication has its remarkable characteristics. Ultrashort wave communication uses line-of-sight propagation mode, which is more stable than shortwave sky wave propagation mode. It is affected by seasonal and day-night changes. Small antennas have small size, simple structure and high gain Directional antenna.

Compared with other communication methods, ultrashort wave communication has its remarkable characteristics. Ultrashort wave communication uses line-of-sight propagation mode, which is more stable than shortwave sky wave propagation mode. It is affected by seasonal and day-night changes. Small antennas have small size, simple structure and high gain Directional antenna. In this way, a transmitter with a smaller available power has a higher frequency and a wider frequency band. It can be used in a multi-channel communication modulation method and usually uses frequency modulation, which can obtain a higher signal-to-noise ratio. The communication quality is better than short wave.
