Installation Method 1 Direct Stacking

Installation Method 2 Offset Stacking

Other Precautions

Antenna Layout

Antenna Installation：
Ensure the two tail antennas are sufficiently spread apart to avoid entanglement, which could reduce signal interference.

Antenna Direction：
Adjust the antennas to point upwards whenever possible to avoid obstruction by the drone or battery, ensuring the best signal transmission.

4PIN Power Cable Connection
The wiring sequence of the two ends of the 4PIN power cable is opposite. Confirm the direction before connecting to ensure correct insertion and avoid damaging the device.
