Hi,
I'm having issues with my DJI Mavic Air 2.
The video signal is very bad where I fly. I live in an urban area and I'm struggling to go past 1km before the video signal cuts out.
With my previously owned Mavic 2 Zoom, I was getting over 5km using the same route as the Mavic Air 2.

I tried re-calibrating the compass and the IMU but nothing changes.
I also tried updating the firmware of the drone and the controller with the DJI Assistant 2 app, but with no luck.

I bought the drone from Amazon in the US, and I live in South Africa. The online support guy I chatted with said I should send it back to Amazon, but I can't afford to pay for shipping fees.
My sister who lives in America bought me the drone.

Please help, Thanks.

Owning both zoom and Air2 , I have found them to be about the same, my set up and environment tend to be a large factor in reception. I did notice at first that RC position needs to change slightly with Air 2 and direction you point antennas helps also I have found signal greatly improves if altitude is increased. You’re in a CE zone getting 5k is well above the average for zoom in CE area.
I found so far in urban area I won’t have any problems at up to 2.5k and I’m certain there is more gaz in the tank. It has also been recommended that you fly in airplane mode on your device, I’m not sure if it makes huge difference but try it, but for me positioning RC and Antennas will greatly improve signal.

are you holding the RC correctly, with the antenna pointed towards the drone? Are you flying high enough? Are you sure there's not a building or something between you and the drone?

Best way to try it out is to go on a higher ground with direct line of sight and then try again.

I found I can get very good range on CE but if there is any obstacle or tree in between, this range can be reduced to 50meters!! Line of sight is vital here

I am in total line of site with the drone and I'm pointing my controller's antenna's  in the direction of the drone.
There are no tree's or building between my controller and the drone.
I am using airplane mode when I fly.

Sounds like you may have a defective unit - I've reached 4.91KM with no signal loss in a CE area.

Then environment could be your problem.

What do you mean by Airplane Mode ?

My Controller has 3 modes, Tripod, Normal and Sport.

Where do I find Airplane Mode ?

Thanks so much for your help.

Sorry should have explained, airplane mode on your phone, so turn off Blue tooth and WiFi.

Similar issues here. I'm lucky to 1.5 km before getting weak transmission alerts. Regardless if airplane mode is on or not.

All good questions, thank you.  I am very experienced and am sure to always have my antennae in the correct position depending on the drone and also adjust the height the further out the drone goes.  
I have returned/exchanged my 1st Mavic Air 2 at Best Buy and am now in the process of testing the replacement unit.

As an aside, I was very disappointed at DJI, as I had sent them several emails through their customer support site, and never received the courtesy of a reply.

I am now awaiting a reply from Customer Service on how to transfer the Care Refresh that I purchased on the 1st (defective) drone to the 2nd (newest) drone, and again, after two days, nothing.  Currently my Care Refresh is showing the serial number for the old, defective drone.  My fear is that if I have to use the Care Refresh for the new drone they'll deny it because the serial number is different.  There was a 28 day gap between the old and the new.

I encountered a similar problem. The remote control didn't manage to detect the signal from the drone even the drone was beside of it. Problem solved after I set the Transmission Channel Mode to "Manual" and Transmission Frequency to "2.4GHz".

If you set the Transmission Channel Mode to "Auto", it will automatically select either "Dual-band" or "5.8GHz" for the Transmission Frequency and that causing the signal undetected. No idea what's wrong with the Dual-band and 5.8GHz transmission frequency settings.
