H.264 Video Drone Video Transmitter Lightweight 110g AV NTSC / PAL
The LinkAV 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 LinkAV 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 LinkAV 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.
LinkAV C654 transmitter can transmit images air to ground up to 20km, depending on mode and frequency.
