The Lumenier Axii HD is one of the lowest-profile patch antennas you can put on your DJI goggles. But does it really perform better than the stock antennas? And is it better to put the patch on the top antenna connectors or the bottom?
Thanks to RCSchim who gave me the Visual Basic script to convert the DJI data to Excel format. Here's his video where he tests a bunch of different DJI antennas: • DJI FPV Antenna tests ...

Every video you tell me I'm going to learn something that day.. And you've always been right. I'm impressed.
FYI Three antennas are used for transmitting and receiving functionality. Only one is used for recieving only. (Per their FCC filings, when wearing lower-left antenna is receive only)
I'm glad I saw this, I just read Oscar Liang review from when they first came out, stating he asked a rep in passing, who stated the top two that transmit and recieve, but even Oscar said in the article he wasn't 100% sure. I'm thinking the FCC would be sure..lol, Thanks Stingy!!
@@ebstmnt this is suprising. Why would there be double transmitting antennas when the main need is a reception of video signal? I would have guessed the opposite. @RCSHIM?
This is all for v1, right? For v2 seems like two are only rx and two only tx (diagonally)? On an analog setup one would typically go for a directional and omni antenna combo on the rx only mounts. Same for DJI goggles v2? And then for tx mounts also directional and one omni I guess?
Thanks for testing the two options. To me bottom patch looks clearly superior. I'll run them as such.
Yay, been waiting for you to do a video on these antennas, thanks Mr. Bardwell 👍
I've been using Triump stubby's on top two, regular Axii patch on bottom. Even though range better than stock, wasn't sure if it could be better. Your results showed, even with top omni as better, it's not a big deal either way. Thanks for another great video Joshua!!
Fantastic work, Joshua! Thanks a lot for testing and comparing them! 😃
Stay safe there with your family! 🖖😊
Thanks for the review Joshua. My order is placed for the panel antennas. I plan to pair them up with my set of Singularity 5.8 Stubbys that I’m currently flying with. Hoping this will give me that little extra penetration in the concrete jungles of Seattle.
Great video. These have been super hyped. Thanks for that last bit saying the TrueRC stubbies are legit. I love them too. Saving me some money here 😅🙏🏻
TH-camr KozakFPV did this same test with AXII HD patches on top and bottom and mixed (one on top and one on bottom), and generally speaking found that having the patches on top provided a higher bitrate than on bottom, followed by mixed.
TH-camr Waldemar Kraus did same test with X-air's (at range, rather than penetration) and found that X-airs on top was better than on bottom, and X-airs on one side and best combination was X-airs on top and TrueRc Stubbies on bottom.
One thing I notice with the AXII HDs is that it's hard not to point them at the ground. Most pilots fly with the head down a little or a lot, and that's not great for patches that are mounted at a fixed angle. One of the advantages of the X-air was that I could tilt it upward relative to the goggles so that it points out straight even when I'm a bit head down.
With the AXII HDs I constantly have to make a conscious effort to keep my head up, which is a bit annoying. They're convenient for transport, but not sold on their performance yet.
Yep, those X-Airs and for sure also the AXII HD's have a very directional beam. In my static hoover test I noticed turning my head significantly lowered the bitrate. So you really have to look into the direction of the quad.
I verified the test on next day and patches on top are the clear winner.
Quite the bummer they didn’t just angle them up a bit. Thicken the plastic on the bottom to compensate for the standard head down posture, or include some sticky shims etc
@@JavisHD glad they didnt do that, i tilt my head back w dji, funny since i did opposite w hdo rapidfire lol
@@flo-ridafpv5713 Perhaps it's time for a higher camera tilt angle? I noticed I used to look up a bit more when I was flying too fast for a lower camera angle and was subconsciously tilting my head up, hoping to see more above the horizon.
Some sticky shims should work for anyone’s preferred head angle
You are absolutely right! Omni at the top is the right way!
Thank you for making this video, loved it.
You’re a content producing machine! Great video!
I just bought dji gear used with this setup. Great intel ❤️
Mario is a Boss. Love his work.
Finally a decent test of Axii HD
Thanks JB for your review 👌👍
Dude..... Your awesome. I sure love your videos.
Thanks for sharing this video Joshua
i love what you write in your door , ill subscribe now!
I just went through the FCC filing on the DJI goggles. Bottom left antenna (opposite side to the battery connector) receives only. Upper left antenna transmits all the time and it alternates between the lower right and upper right antennas for transmitting depending on which one has better reach to the air unit. So you always have two antennas transmitting and 1 receiving at any given time.
Would love to see a new video comparing the original Axii HD patch’s with the new Axii 2’s.
This is definitely worth the money, I use this and it has enhanced my range and penetration a good bit and I have the patches on bottom and I get better range then on top
question are you using these for the dji fpv unit or for quads?
@@joyboy1722 o yea I build my own, I only fly Gravity Loss fpv GRL frames. Their indestructible... But the Dji fpv drone yea No I can’t fly that hunk of laggy plastic, flys like big ole large Potato with motors 😆. On my channel you can see all I build and stuff I post on here weekly some times more then that
@Joshua Bardwell, would you compare these AXII with the IFlight Crystal HD patches?
got the stubbies and they are awesome - better than stock, all the range i ever need - so low profile
Very interesting, dont have HD but very interested in it haha
I got a second hand Dom v3 till then
Thanks JB, always love tuning in and learning something!
Hope to catch your stream soon :)
Great review!
I have them, I found better performance using them at the botton and 2 long polarized on top. Also, when flying in front of concrete I also the 2 menace patches on top for better penetration. I hated to remove my digidapter. But is just 2 screws and i only have a 3" analog quad with a naked hero6 for specific cinematic/job related footage.
Another great informative video for mere mortals thank you, Which patch do you prefer the HD or the Iflight ones I see in some of your other videos???? cheers Wayne
Very informative thank you Mr B ! i have just got some true rc stubbys that you mentioned ( yes i do watch all your vids until the very end ) lol 👍 😎
yes, this AXII video like showing it to all the consumers and tell them trueRC is better in the ending 😂
What about mixing them up. One omni on top and the other on bottom? Say one on the top left and the other on the bottom right or vice versa. Is there a reason why you would need to have the antenna types together on either the top or bottom as opposed to mixing them? Is it because the top and bottom are grouped together? I don't have DJI and haven't read much into how the antennas work on those goggles.
now the same question to the v2 goggles... wich antennas make sense? antenna connector 1-4 dont switch as by the v1 version...
@Joshua Bardwell , you know you can 3d print those sma thumb screw adapters yourself. On thingyverse there's a couple different ones (I use the COFPV Thumbscrew adapter) that will fit snug over the SMA connector and fill the hole completely in the DJI goggles to keep them from wobbling. If they're snug on the sma connector it'll even to pull up a bit when they bottom out (to prevent twisting the jack loose internally).
Print em in harder TPU or PLA. I print 4 at a time to avoid overheating any one. And check your g-code to ensure that the outer walls are joined properly with the inner (it's only 2 layers thick in total).
The point is that for this price they should be included.
This was fantastic. Thank u
Very presentable video, thank 🙇
I've found that in open air (trees, field like surroundings) 4 omnia work great for me but I oddly found the patches work better when buildings are involved.
For penetration I'm using 2 long TrueRC singularities on top and 2 Far Vew helicals on bottom. I look ridiculous but can penetrate 800' of heavy woods with this set up!
Thats AWESOMME! And totaallyyyy worth it!!! 🤟🏼😝🤟🏼
Finally got them.
thanks for the info
Will you do an updated V2 video too? I guess it would be patches on RX and omnis on TX.
Great job man 👍🏻I have them and the true Rc stubs can I use together ? true RCstub on top and patch on bottom or are they match to work better same with same ?
Great video Joshua. Unrelated, I would love to hear your opinion on Redcats aquisition of Fatshark and the role Rotor Riot will play, especially with the DJI partnership.
watch last nights live stream he talks to Drew about it for an hour
@@Ark__Angel yup, just saw a blurb from drew about it. Good looking out.
I bought recently the axiis hd set and they destroyed my sma connectors on my brand new V2 googles...they pushed 3 of 4 sma male pins inside, I have poor signal now...😭😭😭...not worth it in my case!
Hi JB, what would you recommend for an antenna upgrade for the V2 DJI goggles?
I use the stock antennas and I feel like the range is so short and breaks up behind simple things like trees.
thank you very much !!
On an analog setup one would typically go for a directional and omni antenna combo on the rx only mounts. Same for DJI goggles v2? And then for tx mounts also directional and one omni I guess?
The torque spec on sma is 5 inch-lbs. They make special 5/16 torque wrenches just for that.
with your face in the goggle, patch antennas on the left, stubbies on the right. best reception for me.
If you only have two directional antennas first advice was to have them on the right side, now u should connect them on top or bottom. How is that figured out. Have some one made a (vs) test on that.
I considered getting these since I get so much breakup and noise in the video in my backyard (barely 40 feet away on even the higher Mw), but now I’m wondering if my goggle receivers have fried. Do you know of a way to tell for sure?
Thanks!
What would be the outcome of doing one on top and one on bottom to have both directional/ omni for both recieve and transmit?
I try it, for some reason its not work well on long range
Did you face the direction of flight for the second set of tests ("long range")? Because you were facing towards the back of the property for the first set.
Yes definitely.
I don’t really understand antennas.. but I love them. Just like batteries. They excite me for some strange reason
Only for sure, if I understood correctly in your test with the patch down and omni on top is better right?
Noob question but can the antennas on the air unit be upgraded or is it just the goggle antennas that we should upgrade?
great question!
For long range flying directional patch antennas on top much better in my experience, easy 8km range.
For "small" long range like 3-5km, I put patch antennas on bottom and stock dji antennas on top, cause stock antennas little bit above my head, and works better
You've got 8km with these antennas?
I found that the patch works better on top I use Iflight crystal patch on the the bottom I found out that trees go red signal right away....
J put Iflight crystss as l psych on top get better range trough the trees . I use lumineer stubbies
Same deal get better penetration
Wow.
So looking forward to getting my DJI HD Goggles.
Is that script from RCShim public or as a favour?
Would be nice to graph it up.
The script is from RCSChim but I'm sure anyone can get it from him.
So what happens if you put one on the top, and one on the bottom?
RCSchim has done extensive testing on dozens of antennas at different positions on a tripod. He most definitely found that omni antennas benefit greatly from being vertically oriented and not horizontal, or laying on their side. None of them performed anywhere nearly as good laying down. That's where they'd be if you mounted them on the bottom, and that's why they did better with them on top, and I strongly believe that long antennas, that get them above you head, will greatly benefit signal quality because they are higher, above your head, and oriented as they were designed to be, completely vertical.
I'll bet that long omni's on the top, bent straight up and vertical, and good patches on the bottom, would be the very best reception you could get. Most don't want to use those for one reason....they're lazy and don't want to have to take off their antennas every time they put away their goggles! lol I get that, so it's all up to whether you want to take them off each time, or leave a stubby on, and whether or not the less reception and penetration is a big deal to you. Most of us don't use 25mw, so with the higher power, it most likely won't make much of a difference! :)
Most of you don't live in Germany ... fcking radio restrictions
Is the DJI system going to meet the FAA Remote ID crap coming out soon?
Hey, do you think it would be better to have two patches on one side and two omnis on the other side?
You have multiple DJI goggles??!? I only have two sets of analog goggles, one of them a 3 year old eachine box.
Did I just watch 16 minutes about antennas for the DJI system when I don't have the DJI system?
Plenty of us tight here with ya bud, its fun to dream right?? Hahahah
Same.. maybe he will mail me one of the goggles
Hi JB will these antenna work OK with dji fpv that comes in the box as stock.
THANK GOD!
Not sure if I'm completely off here, but I always had the feeling that if you match your rx and tx antennas you get better range.. just curious if it would help to put identical axii Omni antennas on the air unit..?
Matching is only necessary for polarity, the gain of the kwad tenna does control the shape n size of the coverage doughnut tho
I heard putting a crossfire into the drone would help significantly but i dont have the slightest clue how to integrate it on the dji fpv drone and cant find any guides for it
Joshua I have the DJI fpv drone combo. I would like to get the DJI air unit and build my own drone. Can I use my goggles and controller with the air unit? Do they make a drone that you can fly with the controller and goggles that come with the DJI fpv combo?
13:43 well they are pre-bend cables in the box in the direction you supposed to install them, not so sure why you installed them upside down even the connector clearly lined up with the connection on the bottom, but here we go ;)
Because I wanted to find out for myself not trust the vendor.
When are we going to see next gen VTX with MIMO and beam forming
What happenstance! That is the same orientation I run on my goggles and I do lot of medium to long range flying.
im in ur fridge, watching you fpv
Safe to say these are DJI V1 not V2? I was watching another channel that stated due to the diversity of the V1 it's better on top. But the V2 is totally different.
Nonetheless, your testing seems pretty conclusive if it's indeed V1.
I think you did answer, the stubbies on top is better ;)
To these work on version 2 of the goggles? Someone please help me answer this question
I wonder if you could add Sunhans eSunRC 2000mW in between to boost more.
IF you looking for Range - Watch-> Ghost Recon Advanced Tactics PT2 - Best config and separate video flight test
Which
Also, which supplier do you recommend purchasing from?
Lol the face at the end 😂
They look best with the stubbies on the bottom. Surely looks over performance!
I'm gonna get DJI if shark byte doesn't impress me. Would you recommend getting a the DJI TX? I know the air unit has an Rx, the Vista does not, is that correct? What is your preferred DJI setup, like tx, and air unit, or Vista and your TX?
I have dji controller, works with full size air unit and caddx version (lite), goes a long ways too, probably not as far as crossfire, but usually outdoes the video which is your range anyway.
@@trowland9575 I think it pays for itself in the long run, but I hate to use anything except the QX-7 I'm used to, does it feel anything like the QX-7 in your hands?
@@RCOverKill, does take some getting used to. I did tighten down all 4 stick controls as tight as they would go, that helped. You can open up controller and tighten even more (TH-cam vid on it). Not quite a Tarannis QX7 though, but I am fully used to it.
iv got a dji fpv. and the v2 goggles I find the range is really bad in some locations causing me to loose connection. I'm hearing you talk about alot of different parts what is the one major thing I need to change to get the range? is it the anntena
Hello there,
Will there any problem caused by using analog adapter on DJI goggles?
Thanks
Wait, what happened to the b roll intro
What am I doing in here? Trying to find the blue bell!
I thought the data clearly pointed to the Omni's on top being the best
But the dji bottom sma’s are Receive only? And thus should be patch antennas?
Any chance you can compare both AXII vs TrueRC X Air antenna.
On the V2 goggles, 2 of the antennas are transmitters. Which of them are the tx antennas?
And does hooking a patch antenna up to the TX ports help or harm?
Put the omni antennas on the top 2 plugs and the patch in bottom.
just got mine and I saw a little less range than stock, there are just plug and play right?
Do you know if these will work with the V2 of the DJI Goggles.
So will these give the dji fpv drone better penetration also and range ?
Hello doctor copter ..does it work with the dji fpv drone or only selfmade copters?¿
Hi good afternoon
can you please tell me how to fly the dji fpv combo above 500m
or increase to 1000m?
I'm from Austria and need it in the mountains
I just got a set and no 3M Tape. Is it missing or am I supposed to get that somewhere else?
Great work Joshua thank you, is there any reason for testing in 25mbps rather than 50, ? just curious.
I wonder the same. Relevant for folks who fly at 25mW which is not me. Sure I understand using low power to expose a difference but if at 700mW I'm only getting an extra 25 feet of range with aftermarket antennas then I'm not buying them.
on my testing I did the same (without seeing this video here). I'd say it let's you see differences of antennas better (or earlier) - kinda the same why I want to test in 25mw and not 200mw or more...
@@Rcschim Yeah that makes sense, thank you. See your video earlier, very interesting love the graphs :-)
Dji very good
Would the VAS Victory antenna work on the DJI giggles?
I wish you did linear antennas as well.
He did, the stock antenna are linear polarized omnidirectional
Josh, are these v1 or v2 goggles?
