Hello, I wanted to know if it is normal for the mini 3 pro to lose the signal at approximately 700 meters in the city? I make some clarifications: - I understand that it is working with FCC (the 90 dbm line is between 1k and 4k)
- An altitude of about 50 meters
- I use it in dual band
-I try to point the RC controller at the drone
- I live in a small town (18,000 inhabitants), where there are no tall buildings, only houses
- Use Dji RC (with screen and NO external antennas)


Edit: In another test flying at 100 meters high, trying to point the control as correctly as possible at the drone, I managed to reach 1200 meters until it lost the signal.


I see videos of people who easily reach 5000+ meters. Could it be that my device was damaged? PS: I have all firmwares updated
If it is not normal I want to send it to the warranty, but I want to avoid claiming something that may not be a real problem

Thank you

Hi, there
Thanks for your question.
Please follow the steps below for troubleshooting:
1. Change the test environment first to rule out the possibility of environmental interference.
Note: You may use the Auto mode for dual-band frequencies. In this mode, you do not need to check the interference in the frequency band and channel by themselves. The system will automatically select the frequency band and channel with the least interference for customers. This mode can help you check whether the weak signal only occurs in the 5.8 G frequency.
2. If a new test environment does no help, please refresh the firmware version of the drone and the remote controller, and if possible, conduct cross tests with different mobile devices.
3. If the problem persists, please send the drone and remote controller to us for inspection.

Hi, there
Thanks for your question.
Please follow the steps below for troubleshooting:

In a few days I will try outdoors. But my question is, aren't those distances normal? I mean 750 meters of range flying at 50 meters high and 1200 meters of range flying at 100 meters? Should I really go further?

Hi guys new to the forum but spotted this post and had to add to it as I have  the mini 3 upgrading from the mini 2 SE.

I noticed yesterday while the weather is spectacular conditions to fly my drone a Hampton court and I have realized that the range on the mini 3 is not the best and have looked into ways to get better signal range I'm currently using the yargi booster and it does help a little congested areas of 5G polluting the airwaves however I noticed yesterday but while the sun was shining very bright and the signal was getting very low to orange almost red I pointed my controller at the floor as the sun was shining down to my screen utter amazement the signal jumped up to full a fluctuated by one bar minus and absolutely gobsmack pointing the controller at the floor had boosted the signal so dramatically I'm guessing it's bouncing off the floor in some way but that makes no sense or put it be the controller has had an incorrectly fitted trans receiver in the unit ? Any ideas ?

You could try drone tweaks to use the FCC power output

Hi there. The Max Transmission Distance (free of interference) is as below:
FCC: 12 km
CE: 8 km
SRRC: 8 km
MIC: 8 km
Measured in an unobstructed outdoor environment free of interference. The above data shows the farthest communication range for one-way, non-return flights under each standard. During your flight, please pay attention to RTH reminders in the DJI Fly app.

Max Transmission Distance (with interference):
Strong Interference: urban landscape, approx. 1.5-3 km
Medium Interference: suburban landscape, approx. 3-7 km
Low Interference: suburb/seaside, approx. 7-12 km
Data tested under FCC standard in unobstructed environments with typical interference. Used for reference purposes only and provides no guarantee for actual flight distance.

Therefore, your image transmission distance is smaller than the actual achievable distance.

Please refer to the best positions of the remote controller antenna below to ensure that the remote controller and aircraft are in the best positions.


Would you please check whether there are obstructions such as trees or houses near your current flight environment? Please let your aircraft take off in an environment clear of signal-blocking obstacles.

Please go to the app’s image transmission page to check interference. In Fig. 1, the flight environmental interference is lower, while in Fig. 2, the flight environmental interference is greater. Please ensure that the environmental interference is lower to guarantee the image transmission distance.


If the image transmission distance is still lower than the max transmission distance on the DJI official website after the above steps, please collect the recorded video of the image transmission in the app (the video should reflect the flight environment and the image transmission channel page that shows the interference).

Thank you for your understanding and cooperation.

Hi there. Can you tell us what is the maximum image transmission distance you can reach?
If you think it is abnormal, you can also check it yourself through this link: https://support.dji.com/help/con ... StDDhWpMXKppQ%3D%3D

You can tell us your remote controller so that we can tell you the best positions of remote controller antenna.

Looking forward to your reply.

Hi so as you can see from the pictures there is a long water feature that leads up to Hampton court and the total distance from the beginning of the River Thames which leads up to this isolated water feature is 1.4 miles .
The controller is set to auto 2.4 to 5 gigahertz I use a yargi booster it does help a small amount I'm not particularly interested using drone tweaks to make the controller I think that I'm in the United States using FCC rules
I have just moved to the mini 3 from mini 2 se and I found the range was better on the se I understand the difference in Comms ocusync 2&3 but the range is pitiful I'm in the outdoors and far away from interference so I have to walk for miles to be at the side Hampton court so I can film from the middle so one side and then the other in two separate filming and also I'd like to point out that when the signal is almost exhausted I pointed down at the ground accidentally and the signal is almost full strength what's with that ?

Hello, thanks for your response.
I took some photos of the RC controller, the first 2 images show how I start to have the connection in yellow at 941m flying at a height of 120 (if I fly lower I start to have signal problems sooner) and when I look at the graphs of " transmission" there does not seem to be interference, in the other 2 photos you can see how it reached a maximum of 1381m and already there it was losing the signal, upon entering again The "transmission" graphs do not seem to have interference either and yet I lose the signal and the drone goes into RTH mode.
The tests are in the city (it is a small town, it is not a big city, there are no buildings or anything)
Now my question is, is this normal? or does my device have some kind of problem?

Hi, there
Thanks for your information.Kindly remind you that if the pilot's phone has Bluetooth and WiFi turned on, or if the car's dashcam is still powered on, the WiFi signals from these devices can also interfere with the remote control.

Could you please provide the current interference situation through the real-time interference display in the video transmission menu?

We will check it further for you. Thanks

Hi, there
Thanks for your information.
Please check if you turned off other sources of interference you might be carrying. if the pilot's phone has Bluetooth and WiFi turned on, or if the car's dashcam is still powered on, the WiFi signals from these devices can also interfere with the remote control.
You can check the interference situation in the App's video transmission menu.

Hi, today I did a test on the beach (where I imagine there is some interference too) and I reached 3400m and still hadn't lost the signal (the indicator was yellow) but I think I could go a little further, for fear that I wouldn't have enough battery to return, I returned it towards the point of origin. Could we consider that distance as normal?

Hi, there
Thanks for your informtion.
The result of this test is within the normal value range.
Have a good day!
