DJI Relay

The Relay module is designed for DJI Agras models, including T50, T40, T25 and T20P. Check your firmware is up to date on the aircraft and RC Plus before first use.

In unobstructed, low-interference tests, the Relay’s effective distance (CE) is quoted up to ~4 km.
Real-world UK fields with trees, hedges and sheds will shorten this; treat figures as best-case and always verify on site.

Put it on high, clear ground (headland, ridge, or tripod on a pickup/UTV) with line of sight to both the pilot
and the aircraft. Avoid placing it behind metal buildings or dense woodland. Small relocations between blocks can
dramatically improve the link.

No. It improves link quality and range but does not remove the VLOS requirement or other CAA constraints.
Use it to stabilise communications within your approved operating area.

The internal battery provides up to ~4 hours. You can extend runtime using a USB-C PD power bank
(or another suitable 5–15 V source) for long spray/spread sessions.

Yes, the module is rated IP55 for dust and water resistance. It’s built for outdoor use, but still avoid direct spraying,
full immersion, and always dry/inspect before storage.

That’s the intent — by elevating the Relay to clear the canopy or hedge line, you can often restore a clean video/control link in
orchards, tall maize, shelterbelts and rolling ground.

Use one Relay per active operation for predictable performance. If coordinating multiple aircraft or very large sites, plan placements
and radio usage to avoid interference and overlap.

Charge via the supplied adapter/USB-C. A full charge is typically around ~2 hours 20 minutes on the standard adapter.

It operates on 2.4 GHz and 5.8 GHz bands (CE), coordinating with your Agras system automatically. Always comply with local spectrum regulations.
