Product Description


20Km Mini COFDM Transmitter , Professional Long Range Wireless Video Transmitter

LinkAV -C654 1~20km MIni COFDM wireless UAV Drone video transmitter with 150ms latency is new generation of real-time broadcast-quality and high-resolution . It adopts the current leading COFDM modulation technology and relative narrow-band frequency 1.25/2.5/6/7/8MHz(optional), it has the strong anti-jamming capability, overcomes the reflection and cover caused by transmission multipath simulation technique and conventional modulation techniques, to realize high-speed photography and real-time transmit high quality image in NLOS or complicated working environment.


Mainly used in UAV video Aerial photography transmission scenario, the device will transmit video signal to the handheld receiver (or other video receiver equipments) and display video images, can do real-time monitoring and remote command.


Product Features: 

1.Working frequency can be adjustable between 300MHz~860MHz

COFDM Video transmitter Anti-electromagnetic interference performance:
It has superior performance against frequency selective fading or narrow bandwidth interference and signal waveform interference. It has strong anti-fading ability, through each subcarrier joint coding. In single carrier system(digital microwave, spread spectrum system, etc), single decline or interference will result in all communication link failure. But in multiple carrier COFDM system, only a few subcarriers will be interfered What’s more, these sub-channel can adopt ECC to correct error, to guarantee the transmission low error rate.
