Setup: Mavic Mini with 4hawks Raptor SR (5.8Ghz only) and 2 Sunhans 5.8 boosters, and a Belkin dual USB power bank.
I’ve connected everything and I get horrible remote connection to the drone right out the gate. I have to immediately bring it down. The Sunhans are lit up, blinking blue so they are working, but nothing good otherwise. I’ve attached a photo of the controller for reference. Any advice or suggestions greatly appreciated.

I bought the same setup but I haven't installed it yet. Just got the mini so want to have a few flights before installing the SR and the boosters.

Have you tested the 4hawks antenna without the amps? I'm asking because I recently bought a 4hawks raptor sr for my Mini and range was about 1/5 of the stock dji antenna! The absolute max I could get it was ~400m, whereas with stock antenna and a 5$ reflector I got it to 2000m+ in the exact same spot and conditions.

Sent the antenna back to 4hawks and they confirmed that it was working ok, and they do not guarantee any specific range, so 400m is perfectly fine by their standards.

You can check this post out: Signal booster

Update: So I posted a question On Amazon on the listing of those Sunhan’s and asked for suggestions/help or is this setup a complete waste of time and money. I got mixed answers. One of which portly were a guy told me to just power on the right booster. That seemed to help but by that point with the negligible distance increased I cannot justify $200 for signal boosters one of which wasn’t even being powered but rather just connected. Because oddly, if you still didn’t have the unpowered booster connected it seemed to not respond positively. So I returned them back to Amazon and now just use the 4hawks or the original DJI antennas that I modded to have SMA connectors.

Hi,
The transmitter gives to much power, so the receiver gets overkilled.
Try other tranmitter with lower power!
Or only the transmitter and not the receiver amp!
Or use seperated antennas and place them so that they can't see eachother or 90 degrees from eachother!

Must be something wrong. I have the Mavic Mini and SR (CE version) 2,4ghz and 5,8ghz without boosters and can reach 2500m with full signal (haven't tested longer) - I would check again without boosters
