Product Description

20 -Watt Armed Forces COFDM Base Station for Multiple Carrier-Wave





ST9520CZH is digital wireless FHD video transmitter system researched and developed specifically for Vehicles. This transmitter system consist of video transmitter, HD video receiver and necessary accessories (including antenna feed system, connecting line and connector)


System could simultaneously transfer one road HD video (1920×1080p), one road stereo audio frequency and one road transparent serial data. (such as Beidou, GPS position information)


Sagesight series wireless video transmission systems adopt narrowband modulation technique. On one hand, this support unprecedented spectrum effectiveness; on the other hand, increase system receiving sensibility and extend the transmission distance


ST9520CZH transmit power is 20-40Watts, this could provide very robust communication link. It has advantage of small size, light weight and low consumption, which make it an ideal choice for data and video transmission of UAV in high speed condition.




1. Modularized, Low-power consumption design
2. Support system with frequency or inter frequency networking
3. Stable power, adjustable dynamic power
4. Single carrier frequency support up to 4 simultaneous transmitters
5. Encryption: AES 128 bit, can set user’s password
6. HD VIdeo NLOS data transmission
