Narrowband COFDM UAV Video Link 1-3W RF Microwave Radio Link 4/8MHz Bandwidth


Narrowband COFDM UAV Video Link 1-3W RF Microwave Radio Link 4/8MHz Bandwidth





Such new design 1080P HD transmitter is a powerful HD transmit system,using the core of mobile communication technology COFDM(multi-carrier modulation technique),which can transmit good quality and stable full-hd digital video signal under the condition of high speed mobile and heavy building blocks transmission in city environment.Support  full HD 1080P H.264 encoding format and HDMI/SDI two HD inputs(single selection) as well support stereo balance audio input and narrowband transmission system.



  1. Low delay,lightweight,live broadcast;
  2. Support Full- HD quality image;                                  
  3. Support 1080i/1080P HD transission;
  4. COFDM modulation;
  5. Built-in with HDMI or HD-SDI interface(single selection);
  6. Support composite standard video and balanced audio input;
  7. All parameters can be adjusted by user;
