Overview
The Skywalker COFDM Transmitter is a high-performance wireless video transmission system designed for professional-grade aerial, mobile, and remote video applications. Utilizing Coded Orthogonal Frequency Division Multiplexing (COFDM) technology, this transmitter offers robust, real-time HD video transmission with minimal latency, making it ideal for UAVs, drones, broadcast systems, and other mobile video setups.
The transmitter supports both HDMI and SDI input, ensuring compatibility with modern cameras, action cameras like GoPro, and professional video equipment. By combining COFDM modulation with MPEG-2 and H.264 video compression, the system delivers crystal-clear images with bright colors, smooth motion, and minimal visual artifacts, even under conditions of high-speed movement or non-line-of-sight (NLOS) transmission.
With a compact, lightweight, and rugged design, the Skywalker COFDM Transmitter is easy to integrate into UAVs, vehicles, or portable mobile systems, while maintaining long-range transmission capability over several kilometers. The receiver counterpart supports multiple platforms, including Android, iOS, USB devices, and portable HDMI monitors, providing flexible viewing options for real-time monitoring.
