DJI SDR Transmission Combo, 1080p/60 Wireless Video TX + RX, 3 km Range

Using DJI's software-defined radio (SDR) technology, the SDR Transmission Combo sends 1080p/60fps video from a transmitter mounted on the camera or gimbal to a matching receiver up to 3 km away (FCC) with about 35 ms of transmission latency. Operation hops across the 2.4 GHz, 5.1 GHz DFS and 5.8 GHz bands to hold a clean link on crowded sets, and the system penetrates walls and obstacles better than conventional Wi-Fi-based monitors.

Both units carry SDI and HDMI connectors, so the transmitter accepts 1080p, 1080i and 720p signals from cinema and mirrorless cameras while the receiver feeds monitors, switchers or recorders. The receiver's USB-C port also outputs video to a phone or tablet running the DJI Ronin app, and a built-in Wi-Fi mode offers 200 m of short-range monitoring. Power comes from NP-F batteries, USB-C PD at 9 V or a 6.8 to 17.2 V DC source, and each unit weighs about 145 g including antennas.

The combo packs one transmitter, one receiver, a USB-A to USB-C cable and two mounting adapter plates for camera or gimbal attachment. On a DJI RS 4 Pro or RS 4 the transmitter can mount directly and draw power from the gimbal, and the system pairs with DJI Focus Pro for remote lens control, giving directors, focus pullers and clients a reliable wireless feed.
