I recently used the COFDM Wireless Video Receiver with dual antennas for my FPV UAV setup, and it has performed exceptionally well. The receiver provides stable, high-definition video with very low latency, even over long distances. HDMI and CVBS outputs deliver clear, crisp video, while the USB recording function makes saving footage easy. Dual-antenna reception ensures excellent signal strength, and the adjustable frequency and bandwidth settings make it highly versatile. Kompaktan, robust, and user-friendly—perfect for professional wireless video applications.
