Profile
 This transmitter is specially designed for 100km-150km UAV video data link or 3-5km ground wireless communication. It ’s with BNC audio video ports, which is perfect for analogue or AHD cameras. And it is with data interface (RS232/RS485/MIC) for talkback audio or data link with GPS positioning system, UAV autopilot and telemetry systems... And the MIC port is for talkback audio.
 
With 4th generation COFDM （coded orthogonal frequency division multiplexing）modulator, narrow-band, and H.264 encoder technology , it sends high definition images ideal for establishing mobile& rugged wireless video data links on UAV and even block environments, like city. 

Portable Transmitter Features

1. COFDM modulation for stable signal transmission

2. Supporting SD& AHD video input: CVBS/BNC/RCA

3. Supporting talkback audio or RS232/RS485 data link

4. Strong safety with AES user-defined passwords

5. Compact design, low consumption and ultra low latency

6. Supporting NLOS (non line of sight) in fixed installation or mobile use

7. Easy operation by digital panel configuration, and LCD display

8. Military & industrial grade

COFDM Modulator Advantages
1.LOS (line of sight) & NLOS (non line of sight) operation even in high speed mobile deployment
2.Strong anti-interference
3.Strong anti-multipath fading
