20km UAV Mini HD Wireless Transmitter , COFDM Video Transmitter and Receiver for Drones
UAV Video Transmitter Introduction:
It has character of super light weight and mall size,use MPEG2 coding format and COFDM (coded orthogonal frequency division multiplexing) digital modulation, provide high quality image in revolution 720*576.Support NLOS transmission and reception as well high speed mobile transmission.Can be carried in your pocket / briefcase for secrect evidence. it can send live video of the scene circumstances to the rear command post. Widely used in UAV,public security organs, procuratorate, court and security bureau etc.
Features:
- Transmitter only has 195g net weight(without battery),very easy for portable and UAV applications.
- COFDM modulation, Stable transmission
