2) Please launch antenna test function through Taisync PC app. If air unit is about 5 meters

away from ground unit, RSSI should be -35dBm above.

3) Please ensure that the antennas installation of air unit is not blocked by the payload, and

there is no obvious blocking at the ground unit near the antennas, and no contacting with

electrical material like carbon fiber and the antennas of the air and ground units are

perpendicular to the ground.

4) Please do sanity check of Taisync units to confirm if hardware like PA is damaged .

5) Please check whether the downlink mode configuration is reasonable or not, the high-

speed downlink mode will significantly reduce the transmission distance.

6) Please check whether the working frequency is obviously interfered or not, select working

frequency properly.

7) Please check whether there is serious obstruction between the air and the ground unit

during flight, and the complex geographical environment will affect the transmission distance.

8) If above steps cannot solve the problem, please contact Taisync technical support staff.
