DJI goggle patch antenna top or bottom? (Lumenier Axii HD) 

Every video you tell me I'm going to learn something that day.. And you've always been right. I'm impressed.

Thanks for testing the two options. To me bottom patch looks clearly superior. I'll run them as such.

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)

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! 🖖😊

You are absolutely right! Omni at the top is the right way!

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 😅🙏🏻

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.

Thank you for making this video, loved it.

You’re a content producing machine! Great video!

Finally a decent test of Axii HD

Mario is a Boss. Love his work.

RU-vidr 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. RU-vidr 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.

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.

Thanks JB for your review 👌👍

Would love to see a new video comparing the original Axii HD patch’s with the new Axii 2’s.

I just bought dji gear used with this setup. Great intel ❤️

@Joshua Bardwell, would you compare these AXII with the IFlight Crystal HD patches?

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!

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

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.

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

Will you do an updated V2 video too? I guess it would be patches on RX and omnis on TX.

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.

got the stubbies and they are awesome - better than stock, all the range i ever need - so low profile

Great review!

now the same question to the v2 goggles... wich antennas make sense? antenna connector 1-4 dont switch as by the v1 version...

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 :)

Hi JB, what would you recommend for an antenna upgrade for the V2 DJI goggles?

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.

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.

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 ?

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!

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 👍 😎

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?

This was fantastic. Thank u

@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).

thanks for the info

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!

Very presentable video, thank 🙇

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?

Only for sure, if I understood correctly in your test with the patch down and omni on top is better right?

Finally got them.

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.

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?

The torque spec on sma is 5 inch-lbs. They make special 5/16 torque wrenches just for that.

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

I wonder if you could add Sunhans eSunRC 2000mW in between to boost more.

Hi JB will these antenna work OK with dji fpv that comes in the box as stock.

Hey, do you think it would be better to have two patches on one side and two omnis on the other side?

thank you very much !!

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.

When are we going to see next gen VTX with MIMO and beam forming

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

Is the DJI system going to meet the FAA Remote ID crap coming out soon?

I use the stock antennas and I feel like the range is so short and breaks up behind simple things like trees.

Thanks!

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

But the dji bottom sma’s are Receive only? And thus should be patch antennas?

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

Any chance you can compare both AXII vs TrueRC X Air antenna.

To these work on version 2 of the goggles? Someone please help me answer this question

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.

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.

What would be the outcome of doing one on top and one on bottom to have both directional/ omni for both recieve and transmit?

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 just got a set and no 3M Tape. Is it missing or am I supposed to get that somewhere else?

with your face in the goggle, patch antennas on the left, stubbies on the right. best reception for me.

Would the VAS Victory antenna work on the DJI giggles?

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! :)

Which Also, which supplier do you recommend purchasing from?

Does it help w distance. I can only get out a little over 2 miles

So will these give the dji fpv drone better penetration also and range ?

do these antennas works with dji fpv drone that comes with these dji fpv goggles v2?

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..?

So what would happen if you got the iflight crystal and put these on the crystal making 4 patch without them sticking out all over the place? would the iflight patch work through these? Anyone got any thoughts on this i have both on order but god knows when they will turn up.

What happenstance! That is the same orientation I run on my goggles and I do lot of medium to long range flying.

So what happens if you put one on the top, and one on the bottom?

I don’t really understand antennas.. but I love them. Just like batteries. They excite me for some strange reason

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?

Can use this on V2 and V1 or there is a difference?

Noob question but can the antennas on the air unit be upgraded or is it just the goggle antennas that we should upgrade?

What’s the best option if I have mod plate?

Can these be used on v2 with the dji fpv drone?

Still flying analog and looking at hd options. Haven't ever really scrutinized the video from DJI and I noticed pretty consistantaly the image looks real muddy where you fly back between some trees and over a small wooden structure. Is this what digital "breakup" looks like?

Josh, are these v1 or v2 goggles?

In stock soon hopefully?

What's better these or crystal iflight?

Please test the TrueRC antennas!

What was that fast object at 8:58 ?? Ufo ?

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 ;)

Wait, what happened to the b roll intro

Is AXII HD working as well with V2 gogles? I just bought the DJI FPV and I was about to buy this antenna until someone said is not working good cause V2 works on both 5.8GHz and 2.4GHz

I thought the data clearly pointed to the Omni's on top being the best
