DJI Agras Relay/Repeater (T50/T40)

A pole-mounted signal relay for the DJI Agras T50, T40, T25 and T20P, stood above tall crops, tree lines or rises so the link between remote controller and aircraft holds where there is no clear line of sight.

When the aircraft drops behind a shelterbelt or over a ridge, the remote loses its direct path and the live view lags or cuts out. Raised high enough, the relay sees both ends and bridges that gap. It serves one aircraft at a time rather than several at once.

DJI ships the relay with a standard tripod connector but no pole or tripod, so source a support that suits the terrain and crop. Mount it in an open spot at least 2 m above the crop canopy or nearest obstacle, then power it on and pair it from device management on the remote controller. Bring aircraft and controller firmware up to date first. On long jobs a PD-protocol power bank keeps it going past the internal battery, and DJI advises against running it in a thunderstorm. The T100, T70P and T25P pair with DJI's newer O4 relay instead.
