Wireless COFDM Long Range UAVWireless Video Transmitter AES256 Encryption 20KM LOS

Wireless COFDM Long Range Wireless Video Transmitter AES256 Encryption 20KM LOS
 
The C654 transmitter is a mini COFDM video transmitter from Wireless LinkAV, designed specifically for UAV/ Drones video transmission applications.
With proven LinkAV COFDM technology and H.264 encoder technology at its core, the C654 transmitter enables viewers high definition images ideal for establishing rugged wireless video links in all environments including mobile and urban environments.
The small size and ultra-low power consumption make the C654 transmitter ideal for UAV installations, enabling true long range HD quality transmission from these increasingly popular devices for the first time. Optional lightweight, low power consumption amplifiers are also available for even greater range capability.
Wireless COFDM Long Range VideoTransmitter Application
1,Video source+TX (TX omni antenna)+RX (RX antenna)+External LCD display
2,Video source+TX (TX omni antenna)+RX with LCD screen (RX antenna)
