Features:
● One-key automatic satellite tracking and three-axle linkage features rapid spread, collection and satellite tracking; the tracking time is less than 3 minutes; the non-professional operator can quickly master the technique;
● With the compact structural design, good-looking appearance, small size, and light weight, all electric components are integrated into electrical cabinets at the back of antenna; the external cable connection is greatly reduced;
● It is compatible with multiple power and size amplifier; the integration of power source and control system makes the system simpler;
● The azimuth and elevation adopt the advanced clearance elimination technique; the antenna has pointing accuracy; its polarization adopts the step control, improving the polarization control accuracy; friendly human-computer interface;
● Reserve the monitoring interface and software upgrade interface to realize the computer software field upgrading;
● Manually adjust the azimuth and pitching polarization to realize manual satellite tracking.
Applications :
● It has been widely used in telecommunications, finance, hospitals as an emergency response.
● It also can be used for emergency operation, as 1.8m SNG antenna can be equipped with vehicles.
