Product Description

High power 33dBm COFDM Video Transmitter for ultra long ragne UAV transmission


This is an exclusive design COFDM transmitter and receiver. Has a character of low power, small dimension on the transmitter, and we provide more adequate considerations to make it more intuitive and natural.Use H.264 coding format and COFDM (coded orthogonal frequency division multiplexing) modulation, provide high quality of picture in resolution 1080P, short latency.


This special designed system is for UAV long range distance transmission , it is also popular to use in other fields for live broadcast video audio transmission with nearly very short latency 12-25ms and wireless data transmission by RS232 TTL serial port.
