    Welp, stock antenna is removed, Raptor SR is in, and I’ve got to say...I’m extremely disappointed. This highly directional antenna got almost the same distance as my 3” free omnidirectional antenna I took off an old PC wireless card. For $120 I had much, much higher expectations. The Raptor gave...

    Mini 2 battery disassembly

    I’m actually really surprised by this. I thought the mini two batteries were still 18650’s!

    I’ve got a custom Raptor SR coming my way soon that I’m excited to test out. I’ll be sure to report back to see how it compares to the stock antenna. Anybody make any new discoveries with the “B” antenna connection? @Oldi001 I’m eagerly awaiting the results of your RF meter tests! Hopefully...

    Hi Jim, Just ran another test flight. 2x 2.4 omnis plugged in without amps only got me 1600’ before signal loss. Plugged in amps and went out to 14,100’. Signal was fine the whole time and while I was out at that distance I unplugged the “B” antenna and there was absolutely no change in signal...

    Thanks for sharing this. I just got my omnidirectional 5.8ghz antenna and connected it to my 5.8 amp and to the “W” connection and flew out 11,800 ft before signal loss. Nothing connected to the “B” connection. I was hoping I’d see something different flying on 5.8 only with one antenna, but at...

    Yes, you're correct and my assumptions were incorrect after flying with a 5.8 ghz amp and omnidirectional antenna. The antenna needed to be connected to "W" in order to have a successful long range flight on this band. So, like you said, I now believe that "W" is both 2.4 and 5.8. What I'm...

    I did some more testing and finally got a 5.8ghz amp as well. It may not be as I had originally thought but there’s still something going on I can’t figure out. The “W” antenna is what is most important from what I’ve found. I have zero idea at this point what the “B” antenna does or what it’s...

    Alrighty, I've settled (for now) on my desired remote end-state. Went with RP-SMA ends to replace the super skinny QMA connectors and in the process I've removed an adapter (qma > sma) which is always a welcome change. I added some super basic, no-name, no-brand 3" whips which yielded full bars...

    Actually just went out 14,451’ on that Omni after swapping the qma connectors (had to return due to battery, not signal). Looks like I’ve got a bad qma connector! Somewhat relieved.

    No, stock outperformed my RF LINX 2.4 ghz amp connected to a 8.5db omnidirectional antenna. This is the same amp and antenna I used with my phantom 4. I just have to remember to switch the mini 2 to 2.4ghz only mode. I don’t have the alientech duo, just their qma mounting assembly.

    I’m actually kind of upset right now. I just reverted my remote back to stock because I forgot to do a distance test to compare against...and stock absolutely destroyed my maximum range with the amplifiers. I got out to 13,000 ft before I had to turn around due to battery (because I ran two...

    Opened up the remote and confirmed the leads: W = 2.4 ghz antenna B = 5.8 ghz antenna

    Pretty great idea, actually. Thank you. I reached out to DJI, mentioned to MaxxUAV, and posted a few places here about it and haven't heard back from anyone. DJI just kept sending me pictures from the manual showing me where the antennas are located on the Mini 2. ?

    Hi from Colorado

    Welcome from CA. I was out in Castle Rock for a few years and visited there a few times. You've got no shortage of beauty to fly around!

    What I've found is that the Mini 2 remote has the 2.4 ghz and 5.8 ghz bands separated out per-antenna. I have to re-open my remote to trace which is which, but today I ran some flight tests and confirmed (to the best of my ability) that one antenna is dedicated to 2.4 and the other is 5.8 and...
