SDR Transmission, Stable & Anti-Interference · Strong Penetration, Extended Transmission Distance
DJI SDR Transmission uses Software-Defined Radio technology to prioritise signal stability, interference resistance, and penetration over maximum bitrate. That makes it suited to sets where walls, structures, and competing wireless kit break a conventional link, rather than to productions needing the highest possible image quality.
It supports both SDR and Wi-Fi transmission modes, so a feed can go to a dedicated receiver or straight to a phone or tablet when a temporary monitor is all that is needed.
| Product | Includes | Price |
|---|---|---|
| SDR Transmission Combo | Transmitter and receiver together | £519.00, restocking |
| SDR Transmission Transmitter | Transmitter only | £285.00, in stock |
| SDR Transmission Receiver | Receiver only | £285.00, in stock |
Buying the transmitter and receiver separately at £570 costs £51 more than the £519 combo. If the combo is restocking and you need kit now, the separates are available immediately. Individual receivers are also how you add monitoring positions to an existing setup.
The two systems solve different problems, and the price gap is substantial.
Choose SDR Transmission for reliable monitoring in awkward environments, smaller crews, and budgets where £519 works and £1,979 does not. Penetration and stability are the priority.
Choose DJI Transmission for large sets needing maximum range, higher bitrate, ultra-low latency alongside cinema cameras, and integration with Master Wheels, Force Pro, and Ronin-series control.
| SDR Transmission | DJI Transmission | |
|---|---|---|
| Entry price | £519.00 | £1,979.00 |
| Max range | 3km (FCC), 2km (CE) | 6km / 20,000ft |

DJI rates SDR Transmission at up to 3km (10,000ft) under FCC, and 2km under CE, which is the figure that applies in the UK. Wi-Fi mode reaches around 200m, intended for temporary monitoring on a phone or tablet rather than distance work.
Penetration is where SDR earns its place. Where a conventional link degrades through walls, scaffolding, or vehicles, SDR holds a usable feed, which matters more than raw distance on most practical shoots.
Every specification below translates into something on set:
The receiver supports one-to-one real-time voice communication with the transmitter through the 3.5mm stereo jack. A director or client can talk directly to the cinematographer without a separate comms system, which removes a whole category of kit from a small production.
Transmitter
HDMI and SDI inputs supporting 1080p/60fps, plus USB-C handling gimbal communication, firmware updates, and power.
Receiver
HDMI and SDI outputs supporting 1080p/60fps video and audio, 3.5mm stereo jack for audio and calls, and USB-C for firmware updates and video output.
Both units weigh around 145g including antennas, with foldable antennas for flexible mounting and easy storage. Power draw is roughly 8.3W, and both run from NP-F batteries or USB-C chargers using the PD protocol.

Software-Defined Radio handles signal processing in software rather than fixed hardware, which allows better stability, interference resistance, and penetration through obstacles. On a practical set, that means a feed that holds up through walls and around competing wireless kit.
SDR starts at £519 and prioritises stability and penetration at up to 20Mbps. DJI Transmission starts at £1,979 and delivers longer range, 50Mbps bitrate, and deeper integration with Master Wheels, Force Pro, and Ronin control systems.
Up to 3km under FCC and 2km under CE, which is the figure applicable in the UK. Wi-Fi mode reaches around 200m for temporary monitoring on a phone or tablet.
Broadcast mode supports an unlimited number of receivers from a single transmitter. Additional receivers are £285 each.
Yes. Wi-Fi mode transmits directly to smartphones and tablets, which is useful for quick, temporary monitoring positions without extra hardware.
Yes. The receiver supports one-to-one real-time voice communication with the transmitter via the 3.5mm stereo jack.
