DJI's SDR Transmission Receiver handles long-range footage up to 1080p60 with proprietary SDR technology. Using a tri-bandwidth (DFS, 2.4 GHz, and 5.8 GHz) automatic frequency-hopping system, it ensures high penetration and up to 1.9 miles range. Ideal for crowded sets or dense architecture, pair this receiver with an SDR transmitter (not included) for optimal performance.
