- New test setup: DJI Airunit on Tripod moving away (2.3km) with DJI Goggles and compare achived BITRATES. I tested with 2 different powersettings (25 and 200mw) and was surprised that even with Stock antennas you could get a connection at 2.3km thru the fog!
- good line of sight (low fresnell zone intersection)
- big time fog!!! (reduces range about 50%?)
- AirUnit got constant 12v power (thru powersupply which was switchable)
- Maple Wireless L+RHCP TX Antennas (look pretty similar to DJI Stock)
Tested antennas (use the jumpmarks to find what you're curious for):
MapleWireless, Deathray 3Turn, 7Turn
DJI Stock, TrueRC Singularity, Foxeer Lollipop
►NEW!: iFlight ChrystalHD bit.ly/2ILRKDT
Specs: 9db gain, Beam Width: 105° H. 75° V

If you just want the results (ranking) go to 17:56 (but come on - this was a lot of work to edit!)
For the guys who want a deeper insight into how DJI FPV works, we have a nice RCG thread going on here: www.rcgroups.com/forums/showthread.php?3710715-DJI-FPV-Goggles-which-antennas/page2&perpage=30#post45924707
Deamon seems to know a lot about DJI and shared some good info. I added some more bits and pieces I gathered in the last days as well...
FOG doesnt dampen RF that much! Filip pointed me to this interesting article:
www.truerc.ca/technology/what-the-fog
Never thought I would find it interesting seeing a person turning in circles :) thx for the great video!!
As I said, I found it funny myself how excited this got me;)
With the TrueRC Singularity antennas, the goggles, x-lite and accessories all fit perfectly in a single Turnigy transmitter bag with all antennas on.
All I need to fly is that bag, a lipo bag and the drone of the day.
This setup has cut down my "unpack and pack time" drastically. With a battery already strapped in, I'm in the air within 30 seconds, and gone in the same time. Very useful for sktchy spots.
Exploring with an E-bike and flying when the mood strikes... THAT'S LIFE!
ha, I also used a taranis bag for some time (the camouflage one - even better for sketchy spots ;)
Now I use the iFlight backback (once more iFlight ;) - it's not super high quality, but small and light enough. Inside I have a cheap bag to hold the Tango2 and some smaller tools). Goggles stay next to this and theres room for enough batteries and a small drone inside - or a larger drone outside the backpack.
Maybe you've seen it - I like to explore with my KTM bike - but of course that brings limitations as to where I can drive to (but with less effort and faster)
@@Rcschim Of course I saw it. Long time subscriber ;-) I was a KTM rider too. (ABP -Racing tuned Duke II ) It was my escape from the city. Now i sincerely prefer an e-bike for that. Much more relaxing, safer and waaaay cheaper. Sometimes I miss the motorcycle, but then I remember all the tickets that inevitably came with it and I'm fine again. :-)
That was fantastic. Thanks as always for the valuable information!
Thanks a lot!
I just ordered the iFlight ones since I wanted something that does fit in my Backpack nicely while attached and they are way cheaper than the Lumenier ones.
After seeing your video, I think I made the right choice :-)
Thanks for all the hard work and no nonsense approach. Much appreciated.
Hi Mario, I was one of the first to see this video but only today something sparkled in my mind about your testing: When you were testing the omnis and noted an increase in the MBPS when turned about 90 degrees sideways to the signal source, it actually makes sense! Think about it, you noted that most of the work is done by the bottom left antenna and the place you were standing seems to be above the signal source, so when facing the source the antenna actually had its null point aimed to the signal source. When turned 90 degrees to the side the active area of the antenna was facing the signal.
Yes, good idea. I also thought that when I face directly into the dir of tx the omnis don't have good placement whereas the directional antennas are...
Corrosion X application is perfect before flying in that heavy fog! Amazing test! I completed everything!
I have not upgraded to hd yet, but when DJI sends the update that fixes the latency...I'm in!!
Amazing range!!
i bought it 2 days ago, now waiting it to be shipped. Every video i see related to this topic makes me feel more happy that i already bought it. Waiting sucks damn hard. This video is like a super nice teaser, makes me even more happy to see the range is amazing with 25mw ( shi..y EU law), also thinking about what antenna to buy. Thx @RCSchim for that nice rewiew!
The variable latency is a little strange at first but I hardly notice it anymore unless I’m near the edges of range. But yes, instead of a 20ms range of latency, from 22ms to around 42ms at the edge of reception, it would be awesome and unnoticeable if it were from 22-32ms instead. Or even 32-42ms would be fine with me.
Yeah, the system has been out almost 20 months, I figure V2 will be coming out in the next few months.
What latency? I mean if you compare digital with analog even digital has really just a lil bit more latency you can see things much earlier so it compensates it easily
They will never "fix" the variable latency because it's inherent in the way the video link works. DJI's video link is a two way connection and it retransmits lost packets. The number of retransmits allowed for any given mode (low latency 120fps versus high quality 60fps combined with Focus mode on or off), determines how much time it may take to get the next frame as the signal degrades. The best way to "fix" the latency is to pick the right combination of antennas that provides the best signal for your application to minimize packet loss.
If you want a really conclusive test I've often thought the best way would be to use a waypoint mission for repeatability and to log the mbit along with the gps co-ordinates so you could create a coverage map for each setup.
Almost did this, check the Playlist at the end. But my only waypoint copter became unreliable...
@@Rcschim not got a little wing? might be more consistent for orientation anyway.
EVER! The most thorough compairison on these antennas. Great test!
Total respect Mr Schim, for going out in that weather! just watching, made me feel cold :-) New and surprising information from a great test idea, thumbs up!!
Thanks Gaf! Yesterday I was up there again with a friend and 2nd goggles. This time weather was even uglier. It started heavy snowing right after we arrived up there ;)
Also couldn't confirm much since 2nd goggles again work different than mine when they are in the audience mode...
It's exciting and challenging because its is a real sport to find the best possible connection. Especially if you make your own antennas.
this is amazing!! im still using stock antennas and Im still trying to figure out what to buy for long range, my chimera 7 is still grounded. this is so helpful
Thanks for braving the cold doing this test for us ! helps me decide which LR antenna to buy
Please do a standalone, real world review on the crystals. There are loads of people waiting to see what the story is.
Great vid man. Worth my sub.
what more would you want to see in a review about them? If I had the AxiiHD available, I could maybe do a shootout between those...
A shootout between those would be cool. Bit realworld.. flying bandos.. forests etc. And even a comparison with stock antennas would be good.
I think a lot of people would be keen to watch that. So many groups im on are clambering for reviews on these.
@@zulutsunami1810 i will try. Problem is, here i get to fly mainly on weekends now since before and after work it's basically dark, cold and/ or wet ;)
Flew today from my terrace with the new chimera. Worked great to 1.7km with full MBits.
So for me they are great and they deserved their permanent install on the goggles. Greets and thanks for Video idea and feedback!
Thanks for this vid. And the feedback. Ive been a bit worried about em seeing as i just bought em and am waiting.. but found no reviews till yours. Its put my mind at ease somewhat.
Look forward to your next ones too.
You did an excellent job. Thanks Mario 👍
Just watched Mad tech' short info on the dji goggles V2... seems like they will behave differently regarding antenna placement? I guess we will se you testing this in a future video..? ;) Will be very interesting! Thanks for all you do for the hobby btw!
We will see, currently I dont see many reasons to go for V2 goggles. If the DJI drone is really THAT good (and looks like it requires V2 goggles) then - maybe... But my current DJI FPV drones are really good and I dont know how much this could be improved (but I love to be corrected by techological advancements ;)
@@Rcschim yeah, for v1 users no reason to uprade yet. I'm new to dji hd fpv, so my main reason for getting the v2 is the alleged video-out to smartphone via usb-c..
Great test, danke! I wonder what the people were thinking in the cars driving by, but who cares! Great commitment to the hobby! Thanks again
Very well put together a video. Thank you very much for doing this and the time it took you I appreciate it. Happy flying for Michigan!
Fantastic testing, Mario! Thanks a lot! 😃
Really interesting results!
Stay safe there with your family! 🖖😊
Nice, first review of the iflight and I'm impressed for the form factor. I saw when you rotated to about 15 degrees the Mbit jumped up to high 34 so this confirms their advertised displacement.
I have the axii hd and didnt like the lower mbps off to the side n behind so added 2 more hd stubbys to bottom, now just connect patches as needed. Watch the 4 truerc stubbs vs the iflight when he turns 180, mb is doubled, soo 4 omnis better for most spots for me...trees mixed w concrete usually
@@flo-ridafpv5713 nice! Thanks for the insight. I fly planes to mid range so facing the plane is fine.
@@ZaksterBlue ah yea u should have pefect mbps then
Interesting results. I just ordered the iFlight Crystal antennas, mainly because the set is so small. Good to see that the performance is also good.
Yep, I was surprised with the performance! Now, within having it tested i use the truerc singularity in combo with the new face plate
Would be nice to see True RC x2 air only at the left side.
Good test! It nicely showed penetration, nulls, head blockage and orientation. Great job!
Could have been more methodical and even (same turning speed) but I guess it works. Thanks
Thanks for this review! I am really impressed with the Iflight Crystal, and the very convenient form factor and look are a plus.
Agreed, I like the 3 different designs. Was great because my orig faceplate has had a few dents and scratches already ;)
You've earned a subscriber! Thanks for the straightforward testing and concise results!
Welcome James T (Kirk?)
Just what I have been waiting for! Great content! Thanx Mario!
Sehr geil!!!
Comon we all anxious for you to test out Dji v2 goggle patch antenna placement lol
That's very interesting, I've been using my TrueRC X-Air on the left side and it was great but had to move it to the right because I attached a BDI Digidapter with Rapidfire which takes up a bit of room on the left and I do find myself leaving the TrueRC stubbies on the goggles more often now... Thanks for the thorough test, just with you tried X-Air too in the same conditions 😅
and did you notice less antenna-performance with the Xair on the right?
Mostly we dont fly far enough to even have to use the best antennas I guess :)
I dont have the normal xairs. Got a special variant of the xairs (but that is more for complex bando stuff and not LOS longrange - so a comparison wouldnt have been fair).
I guess the normal Xairs are a bit over the 3Turn helicals from Henrik...
@@Rcschim I can't say I noticed a downgrade in performance directly, but I definitely suddenly found myself using it less, so in hindsight it might have been that I noticed less of an improvement using it on the right.
I was just missing the Lumenier AXII HD Antenna with the patch =) but it's a great video overall! =)
Didn't have access to them... but I guess they are similar to the iFlight Chrystal
@@Rcschim probably, well, I guess you know more than me about it.I have been thinking to get some antennas for freestyle-mid-range for DJI goggles but I am not sure which ones I'd get yet ...so I am always so excited when you're coming up with a video :)
I have the axii hd and didnt like the lower mbps off to the side n behind so added 2 more hd stubbys to bottom, now just connect patches as needed. Watch the 4 truerc stubbs vs the iflight when he turns 180, mb is doubled, soo 4 omnis better for most spots for me...trees mixed w concrete usually
@@Rcschim where can I get 3Turn Helical antenna? I have been looking around and I could not find it or you buy them separately and put them together?
@@aerialclone_official check the infoboy, you just need to mail Henrik - he's fast in responding and happy to sell you those nice antennas!
Thanks! Great analysis, especially this part about left/right antennas, this is very valuable!
veery nice! looking forward to my iFlight patches soooooon. there are 3 weeks in the mail already
I like them currently. Very good compromise - no problem with signal so far. Had 1.5km flight with the little iFlight Chimera4 yesterday. Man this distance was scary enough for me. full bitrate most of the time! No need for bigger antenna ;)
good testing procedure. I was really hoping you'd test/compare the True-RC X-AIR 5.8! Can you do that next time around?
I don't have them. Got a special version of the xairs which are for bandos more, but I wasn't supposed to make a review.
A friend has the xairs but rhcp, so I couldn't test yet, will do next time, but now it is freezing cold...
@@Rcschim I thought the DJI versions were both LHCP? Lucky here to live in a warmer climate (Calif.) Thx for your response.
Thanks RC Shim! As always, great work!
Really appreciate your time doing all this testing!
Mario, you always do your best at editing and giving everyone good information. Thank you.
My question is, have you found that manufacturer antenna ratings seem to be correct? Does the gain/angle on a patch seem the same as what they claim?
I run the menace patches on the bottom and true rc stubbies on the top. I see a much better all around signal quality this way vs stock dji antennas, it also seemed 4 menace patches worked better, even when flying behind myself. I usually sit in the middle and fly all around myself.
I want to go with the iflight or axii type antenna because they are easier to store vs the menace patches, I just don't want to loose any performance. Do you think I will?
You are the go to FPV antenna man!! Thanks again and happy new year.
Thanks for the nice words!
Of course not all antenna manufacturers specs are true. Like the C ratings on LIPOS are seldom true. And if you are the only manufacturer with true specs, your antenna seems lame...
I only have one menace pico patch that I tested - and it did average well compared to other patches. I guess the AxiiHD or iFlight Chrystal will be around the same as your current setup + the convenience. If you need good range in one direction, just remember to tilt your head a bit to the right, so the left antenna is oriented best ;)
Happy NY too! Happy flying!
Good stuff!! Doing something so simple yet so revolutionary. Like a magic trick. Once you show us the magic, we're all sitting here going,.. "why didn't I think to just cover the antenna with my hand?". :D
Now for some critiquing: So now we have the opposite situation as your other videos. Since you used a left and right on your air unit, the Maple Wireless and Foxeer had an unfair advantage. But even with that advantage, Maple doesn't seem any better than any other "patch" system.
It is interesting that the "best" antenna port is that lower left one. That is the one the FCC docs says is receive only. Maybe it's the most sensitive since it is not transmitting? Covering up the others should basically be making this like an audience mode goggle.
Seems like I remember you having some ORT helicals. Maybe test with TrueRC Singularities on 3 ports, and a single helical on that one receive-only port. I think your 3 turn death ray will still beat it, but it'd be interesting to see how big the difference is. Might be an option for your everyday bag since you'd only be swapping one antenna out. ,....and now reading in the comments, I see I'm not the only one suggesting this.
Perfect review! thanks Mario - just what I needed to watch
I am fogging liking your test Mario :-). Good job!
love your antenna testing
Sehr interessant! Hab mich schon gefragt, wie die neue IFlight Antenne performt.
Hab noch nicht besonders viele Flüge damit - aber momentan bin ich recht zufrieden. Ausserdem schaut die einfach gut aus! Und die Faceplate ist genau gleich groß wie die originale. Dh. wenn man die AxiiHD hernimmt: hier kleben dann noch ca. 5mm Patches drauf. Dadurch könnte ich z.b. die Helicals von Henrik nicht mehr drüber montieren.
Wie gut die kleinen Stubbies von iFlight sind hab ich noch nicht getestet, sondern einfach die TrueRC Singularities genommen :)
Habs schon weiter oben geschrieben: gestern eine kleine Runde mit dem Chimera4, 1.5km ganze Zeit volle 50mbit. Ich brauch wohl selten mehr Antenna-gain ;)
I was just thinking "where's Mario" and this video popped into my feed :-) I would like to see how things would perform with a 3-turn helical on the bottom left and stock antennas on the other three positions. I think the results would be surprising!
Hehe, I was busy, and I did this test twice here. First day with insta360 one r cam, but audio was terrible (never do a full review with new, untested gear ;)
2nd day was foggy then, but still fun.
I guess 1 helical bottom left would be all you need.
It would be interesting to now test the upper ranges of 700mw to see if it still holds true or if we see an increase from the other antennas.
@@drakinfpv9629 better make that 1200mW, when you're already at it ;-)
If the bottom left port is receive-only then it might be more capable of a receiver on the sensitivity side, thus might explain why it works better with a higher gain uni patch antenna, would allow for more error correction. I presume the transmit capable receivers can only do half-duplex whereas the bottom left will be always receiving.
@@eyeflytinkerings the 7turn death ray will hold over 30mbit at 13km on 1200mw👍
EXCELLENT video, thanks for the crazy amount of work!!
thanks for the comment and the appreciation! there's enough motivation on my side if I want to learn facts by testing things (where little to no information is already available). the overwhelming feedback of the community is an additional motivation - love it! greets!
thanks for the test mario, keep up the great work. For me the AXII HD Combo works great and i think the results are similar to the iFlight Antenne Combo. Greetings from constance
I have the axii hd and didnt like the lower mbps off to the side n behind so added 2 more hd stubbys to bottom, now just connect patches as needed. Watch the 4 truerc stubbs vs the iflight when he turns 180, mb is doubled, soo 4 omnis better for most spots for me...trees mixed w concrete usually
@@flo-ridafpv5713 that's a good idea 👍👌
@@blue1105moon 👍🏼👌🏼
Great video Mario ! thanks for all of these comparisons
wow thank you for giving very good information, what happens when you connect 2 antennas with the SMA Plug Dual Coaxial Adapter?
Hi, thanks for this great video and tests.
Can you try the dead zone of the omnis or talk about it? I'm curious how it handles in digital (I think with the placement of these connectors it's better to put the antenna horizontal like we did in analog, not like the stock ones)
Have a nice day, Jules.
Very nice video Mario! I want to buy a pair of goggles and is a hard decision what to do. 👍
I didn't try the avata or the new DJI Goggles 2 yet (but they're expensive).
The DJI FPV Goggles V2 (the ones which came with DJI FPV Racer drone) are probbably the best buy for DJI atm.
The DJI FPV Goggles V1 are perfectly fine and can be bought used for quite cheap I guess - but they will not be future proof and I fear they will not work with the new DJI Airunit3 or the Avata.
Only the new Goggles2 are compatible even with a mavic3 pro (which is also a nice option).
@@Rcschim Thanks Mario, I have two nephews 10 & 12 that want to learn to fly so I want to get a good pair of goggles. I dont mind paying a little more. 👍
Very nice roundup! I would have love to seen how the AXII HD stack up against the Flight Crystal, any good comparison data source?
I'm quite sure that they perform very similar. After the iFlight suited my goggles so nice (and the look is great) I didnt have an interest in trying to get the axii HD (I've asked several sources for a review sample...)
Awesome test! Thank you for the effort you put into this :) I am subbed now, and I have also joined your patreon. Keep up the good work :)
thanks for your comment and also the patreon! Another Henrik (like the creator of helical antennas). greets, Mario
What a brilliant video! and i got a shout out........ Would love to know what all those drivers thought when they were passing behind you. lol. Again those foxeer 3 antennas perform very well considering the price comparison with the others....
Hi Jason ;)
Was i right? Did you recommend the airunit walkway method? Foxeers are 👍
@@Rcschim I actually don't think I did suggest that..... I'm not that clever! 🤣🤣🤣🤣 but I'll definitely enjoy the moment of youtube fame! 🤣🤣🤣
Perfect review, u got new sub haha. I bought 3turn antenna today 😌✌️
Wow nice work shimster! So 2 3 turn helical on left side is all that is needed?
Thanks Philster ;) Yep, would say so - but normal 3turns are a bit annoying to mount. So some kind of 3d printed part to support them would prolly be good (similar to what Henrik did here). Currently I fly mostly with the iFlight Patches - simply because it works well enough (if you dont need crazy range).
Nice video and really nice method to get a fair test results on the antennas would love to se the TrueRC X-AIR 5.8GHz Antenna in the same test, as people say they are the "best but bigest".
A friend had those with him today, but he was in audience mode - there they didnt perform as they could I guess. They should be around 3Turn helical perf I guess. Should be better than normal patches, but they are really not convenient to screw on!
@@Rcschim Okay! Yeah they are kinda big and bulky to, but that is the 3Turn helicals to and maby more fragile?. Dont know wich ones is worst to screw on but would have been fun to see if they preform the same.
The 3turn death ray is accually pretty durable, the wire is 1.3mm stiff solid copper wire and they are made from petg plastic.

Okay that's nice to hear! unfortunately i havent bought the dji goggles yet but i deffenently will get the 3 or maby 5 turn death rays WHEN i buy the dji's! Ive just got into the hobby this summer and i love it, and i need to buy some here and there. Great work on the death rays, like look!
Seeing it only care about lower left antenna port is surprising.
Can you please do *one* sanity check, and repeat a couple of these tests with the AU having the same polarity antennas? Don't need to make a video. Just want to know if you see any difference.
I suggest this because DJI's FCC documents say that it uses CDD (Cyclic Delay Diversity) which means it transmits every packet twice with a very small delay between, and the VRX chooses the best of the two copies. It is *possible* that it's transmitting the 2nd packet on the 2nd AU antenna and receiving it on the right side goggles antennas. If that were the case, then in the situation where you have a polarity mismatch between the 2nd AU antenna and the right side goggles antenna, it would make it appear that the right side antennas do nothing.
Hi Deamon! Nice to see you here!
The day before this I already tested a lot, there I had 2 stock LHCPs on the AU. Same result. Had this on the goggles with all different sorts of antennas (of course not only the maples which again are L+R).
Today I wanted to confirm that it's not just my goggles. Had a friend up there with me, 2nd pair of goggles. Problem: if his goggles are not bound to my AU, he's just in Audience mode - there it seems to be equal on all antennaports...
I'll test more on a different location maybe with more pilots.
TrueRC also got a lot of feedback that using the LEFT side is better.
Then Henrik pointed me to this info (maybe you've seen it already). More and quite interesting infos from FCC? testings. Saved it in "our" DJI goggles thread where you already added a lot of great infos!
www.rcgroups.com/forums/showthread.php?3710715-DJI-FPV-Goggles-which-antennas/page2&perpage=30#post45924707
I like this test the best and the overlay for mbit
Thanks, have you seen what I did there with the bars below MBit? Modified my SRT conversion script to have one bar for each MBit - so it's a visual sign of how good the signal is.... I wish DJI would give us something similar in the OSD.. .(and make the bars RED if to low)
Hi Schim! What another nice test! It is a clever, safe and efficient test. Much appreciated! But one question, why not compare with AXII HD together? 😊
I dont have them AxiiHDs yet. Asked at Banggood, will probbably get them next month (they have a certain Budget for you tubers). Asked at other shop but it either wasn't available or they didnt wanna send me. Since I have so many really good antennas, I dont wanna spend 70$ on my own... I'm quite sure that the Axii will be around the same perf than the ChrystalHDs (and the ORT digi eyes). Maybe a friend has AxiiHD to test for me, then I could just update the info here...
I am watching all your videos and I am trying to find the best antennas for long range. I am grateful for all the time you’re putting for us. Could you try the Pagoda antennas on the Air Unit?
We used to fly really long range with Pagoda antennas. Would they work for a digital system?
Thank you once again for all the reviews!
Maybe pagodas are a idea on the copter. But: I'd have to get new ufl lhcp pagodas (all my others are rhcp). And also: if you have good gain antennas like the helicals, you run into the new hard limit of 13.3km (heard reports, that guys had 35mbit at this distance still, but there it dropped because of how DJI works, there is a sync pulse which puts a hard limit on the range).
Schim I really enjoyed this. Have you managed to compare 2 True RC X Airs ? Keen to know how they stack up. Thanks 👍
Yes, but only some prototypes. I'd say they (2xair) will be between 3 and 5 turn helicals, where the helicals are much easier to mount.
@@Rcschim I had them mounted horizontal and it was dreadful reception as they were facing I wards due to the mounting issue. Now they are vertical facing outwards and very improved
That helical antenna performance is awesome! Is it on sale?
Hello mate, yes you can order it by email...

Thanks for perfect review!!!!
Nice test,
In case of lollipop ,
I suspect the metal front cover of goggles made reflection signal to good position of antenna. Could you try in next test please?
What exactly do you want me to test? The reflection?
I swapped the faceplate (iFlight colorful one is plastic, because antennas are behind it).
Henrik also meant: his helical antennas (which are mounted together) have a large copper base - this is a good reflector, so you even get signal behind your self ;)
@@Rcschim could you please test with 4 foxeer lollipop compare with and with out metal face plate just confirm metal plate has responsibility to long stick antenna or not .
Awesome. Thank you.
Excellent video Mario!! Great test set up, actually more interesting with the fog!! I was also interested how when you did the turns, all antenna did better side on when the left side was at 90 degrees to the air unit than when you turned with the right side facing 90 degrees..again proving your “ Left side Theory” (or more importantly Bottom Left Side Theory”!!). So do you think a good patch on the bottom left only and 3 omnis on the other 3 poles would be a good all round set up??
Sure. 1 3turn helical would probbably be enough. Maybe add a 2nd on LEFT top (pointing it to the right more) to have wider beam even.
At least I know now - on my previous tests I sometimes have put patches on the right side - and thought the antennas are not that good - while it just was the way DJI goggles favor ports. Still wonder why and what the right side is there for (only 2way comm with airunit?) Today I will prolly meet with a friend to test his goggles as well to confirm left theory (but I also read from few others about the same)
@@Rcschim thanks Mario. Sounds good. Would love to know results of tests with your friends googles to confirm your findings! Brilliant work. Talk soon. Mark
@@marxdroneworx so far the testing with my friends goggles wasnt very conclusive: he could only test in audience mode - which we both asume acts totally different than the normal mode. In audience however, all antennaports worked the same way.
We would have needed to go down to the house, bind his goggles to the AU and go up again.
Time was running out and heavy snow interrupted the testing efforts.
So I still dont know if my goggles are maybe defective (but I doubt that).
@RCSchim thanks for the update Mario..shame the snow came in, sure you will try again when you can. Didnt sound like your googles are defective. Will stay tuned for updates👍🏻
Hello RCSchim :) thanks for your videos, do you have a video on what to get when you want to start, Antennas, Equipment, Drone etc? Would really love to get your opinion since i want to get a good first setup with DJI FPV, thanks :)
Love your tests :-)
Regarding the iFlight Crystal HD: In their product pictures they do put the patches at the top, and the stubbies on the bottom. In your test you switched this around (which i can relate to, as this has been the usual place to put them). I wonder if there are different results with switching positions.
It's easy to see, when you use 4 helicals on all ports and just cover single antennas. That showed me that left side is better than right.
@@Rcschim understood regarding left side and right. Yet i was referring to "upper side" and "lower side". In the product videos of the iFlight Crystal HD they do connect the antennas to the upper side, not the lower ones. Which is weird, as patches usually go to the lower side.
See this picture for reference: shop.iflight-rc.com/image/catalog/product/Crystal-Antenna/crystal-hd-antenna-20.jpg
@@eyeflytinkerings I understood what you mean. I dont think it makes much difference if patches are top or bottom. But in my case it was a huge difference if they are right or left...
Please test lumenier axii hd)
I have the axii hd and didnt like the lower mbps off to the side n behind so added 2 more hd stubbys to bottom, now just connect patches as needed. Watch the 4 truerc stubbs vs the iflight when he turns 180, mb is doubled, soo 4 omnis better for most spots for me...trees mixed w concrete usually
great vid. would be interestet how the truerc patch antennas perform compared to the other ones.
big thx 4 your great work.
Today a friend had the TrueRC Xairs (RHCP) but he was in audience mode while I was on normal mode. There the iFlight patches performed about the same as the TrueRC Xairs. But keep in mind, in audience mode you get a range reduction!
So I estimate those TrueRCs to be between patches and 3turn helicals, maybe around the same as 3Turns. Hugo claims they are between 3 and 5 turn helicals even. Maybe I can test this the next time...
Today we only had 1hr, and right after we arrived up there heavy snow began (last time fog, now snow, what's next? :)
@@Rcschim would be great to know. Myself fly 2 truerc patches. I don't really care about the size thing. Just like to get the best range possible on my setup. Thx for your answer. Looking forward on your channel. Keep up the great work. Greets from Switzerland.
Great job!!!! Thanks a lot!!!!!
Great test, thank you! could you try the 3 turn on the bottom and the trueRC singularities on top?
I could, will probbably today. But I'm quite sure that the gain of 3turn will be same as if I only used the 3turns x4. Only possible diff: when turning away from Airunit in my test, the omnis would then make a bit better reception. But not by much - the 3turns are also quite good behind them...
@@Rcschim Cool, if there will be no negative effects on reception it could be a more compact alternative to a full 4 3turns
Great video. Thanks! Do you think the Furious V2 Smart case for DJI has enough voltage at 8.3/8.5v to power the DJI goggles correctly. Do the goggles work any differently if powered by 14.8v versus 8.5v? Trying to research before purchasing. Thanks everyone and RCSchim.
I've seen ppl using 2S (7.4v) for goggles - dont think it makes a difference. Some also wanted to use LION cells, but there you can only use 50% of the capacity, since they drop further down in volts than lipos and the low volt protection or alarm kicks in too early (I read that didnt test it myself).
I just use some weaker but larger 4S packs that I dont fly anymore (with a long cable in my pocket rather than on the head). the goggles need quite a lot of power, 1800mah 4S is good for like 1hr of flying I estimate...
What about the LUMENIER axii 2 hd and the LUMENIER stubbies
Thanks for that useful video. 👍
Do you think that performance of Iflight combo is the same as Lumenier Axii combo?
I'm quite sure. Optically they are even better I'd say but that's a matter of taste
I assume these are v2 goggles?
No, they are v1s
Have you ever tested the True RC X-Air 5.8 for DJI? Is the bottom left thing (being more powerful) the same with all the antenna's, or just the Deathray?
With all antennas i saw the same. I just did cut away this so the video isn't so long
On 700mw, it isn’t the case. It just needs to have 2 directional antennas (any ports) pointing at the source to recover from no-signal to a very blocky but “moving” image (I have had the air unit’s camera looking at the ticking needle of a clock) . I could not see any difference in image quality regardless of using the 2 left or 2 right ports. Slightly better image quality (barely noticeable unless you focus on the details) with using 2 bottom ports as compared to the 2 top ports in my test.
@@terence79chan with enough power you dont notice the difference that much I guess. This is why I always try to do my antenna-testes with lowest possible power.
@@Rcschim Thanks Mario, I understand now. I will use the 2 left ports for the directional antennas. Wishing you and your family a wonderful year ahead!
Do you have a link to buy the 7 turn antenna?
Thanks for the testing 👍👍👍👍
nope, but please check description for the Mailadress from Henrik - write him a mail he's usually really fast. Good descision btw!
Looks like the iflight crystal combo is a very good choice...! have you tested the lumenier axii 2 HD (also patch and omnis) combo and can give me a advice which one I should buy
Yep, I still like the chrystal HD. Today I will for the first time see the AxiiHD on a friends goggles - but from what I heard - those patch antenna thingies are all quite similar (AxiiHD, ORT Digieyes, ChrystalHD). If I want some more extra range over convenience - I attach the Helicals from Henrik (the Deathray). Good thing with ChrystalHD: I can leave them on because they are flat! - not like the Axii which add ~5mm ontop your faceplate - so I can install the Helicals (or something else) easily OVER the chrystals....
@@Rcschim and what du you think about the omnis of the crystal/ AXii? Are there both simular in quality?
For the Dji v2 goggles I hope the omni/patch combo makes still a sense... because i have read about the differents between v1 and v2. no more switching between tx and rx, That means no rapidfire?! Is omni and Patch nevertheless a goto recommendation on the v2?
Ps. Thanks for your support!
@@renesfoodpassion honestly: I didnt test much with V2 goggles yet - so I have only "hearsay" knowledge ;)
The little stubbies are all quite similar in performance as well - but a good day of free time, a few packs and I could find out how they fair.
On the V2 goggles (but when they run in V1 mode - the DJI HDL mode) I think they act the same as V1 goggles. Only V2 goggles in DJI FPV Drone mode (occusync3) - there it works differently - this is all very confusing to the customers I guess. So far I'd still stick with patch omni combo - and I will fly more this afternoon - maybe I can gather some new knowledge :)
@@Rcschim ok cool! Please let ne know about your afternoon flight 😜
Thx mate great review. Question what antennas would you recommend on the airunit?
Just the stock ones or the caddx vista antenna also seems to be a bit better.
Foxeeer lollipop worked good for me as well, just not the lollipop micro. They are crap.
I try out the albatross 15cm ones. Hope this helps for longer range
VAS Cyclops V2 vs Deathray 3Turn/7Turn ?

@@SLINGSHOTandMOLOTOWS thank you , so which do you think is better?
@@TheYoukill Im the designer of the death ray so it does not matter what I think as I should be concidered potentially byist🙂 but the deathray kills it, I seen the graphs👍 also a small increase in range throug alot of objects equals a massive increase of range for a unblocked signal
Also für die Idee erstmal nen Like :) Bei einem mix aus Omni s und patches wohin dann die linke Patch oben links oder unten links :D oder beide patches links und die omnis rechts ?Wenn es um einen Allrounder Setup geht.
Danke, bei 2 dir und 2 Omni, definitiv dir auf Links, Omni rechts. Wenn Du nur eine dir Antenne hast, diese auf unten Links.
fog-seer...flagged. hehehe... just wow!, would be so tempting to fly over that fog but it looked a bit dynamic and changeable. i am still trying to grab a hero 6 on ebay, but after that, its dji system. even if i have to starve to get it.
Ya might consider skippin the gopro...i just superview my dvr ...looks great
Agreed. Sure- reelsteady naked gopros6s are a thing - they look cinematic but also unnatural...
Better to get DJI sys - gopro footage is overrated :)
What about the axii hd?
Hello, how about the TrueRc X-AIR 5.8 For DJI FPV ?
I could only test a special variant of the xairs (not part of this test). they are for sure one of the best antennas, but for me the mounting is horrible. the helicals from Henrik are way easier to mount (and even keep them on - at least the 3turn variant). Or just use the iFlight or Axii Patches - for convenience. Flew 3km with iFlight patches yesterday, got to around 30mbit when I turned around (only because of battery, barely made it back with my 1600mah 4cell, but that's a little OT now :)
So I guess we should be running stubbies on the right top and bottom and patches on the left top and bottom ?
yep, it's now well confirmed that bottom left port has the most impact on good reception.
@@Rcschim thank you for your testing 🙏 😊
Also do you think on that if flight patches front plate if you put a carbon fiber sticker say over that whole front plate do you think it would affect the range at all?
The new faceplate from iflight is made of plastic. There is even an cf version.
If you use your own sticker I'd day or depends on the materiel. Most stickers should be ok. Real carbon would be a problem :)
Why no axii hd? Hehe anyways nice test review! Thanks!
asked a few shops, nobody wanted to send (didnt have it on stock) and I didnt wanna spend 70$ since I already have enogh good antennas :)
I suspect they are quite similar in performance as the iFlight ChrystalHD
@@Rcschim thanks for the video. Great help
Dear Mr shim LOL I have a question for you and hope you could answer it and help me out as I value your input just order the iflight patch antenna set and would like your input on whether to hook them up to the top ports on the goggles or the bottom ports thank you and any other advice you have concerning that is much appreciated thanks Jason
Patches bottom and little omnis top works best for me
Thank you very much so that I flight crystals patch kit that bolts to the front I saw in your test it looked like you had them hooked up to the top but you're saying you would recommend hooking them up on the bottom instead? Thanks again much appreciated
Are you going to do a test with giggles 2 and truerc x-air2?
Don't plan on buying the g2 and the one guy here that had em, sold them already...
@@Rcschim understood. Thanks 🙏
I guess the axii HD would be pretty similar to the Iflight CrystalHD? (I haven't actually checked the antenna specs)
I agree
Your running an adapter on the lollipop?
yep, RPSMA to SMA - so I could use my older antennas.
are you standing under huge power lines?
:) yes, do you think it affects my results? Not perfect, and I wouldnt fly longrange from there I guess - but since the results were really good it's OK.
Servus, sag mal hast du auch die Menace DJI Digital HD Antennen? oder die Lumenier AXII HD? oder die Antennenfreund Antennen ? xD Würde mich mal interessieren wie die abschneiden
Nicht speziell die menace hd, aber die normalen menace pico patch. Die sind ganz ok. Ich denke eine menace auf unten links und ein paar stubbies...
If the left side is more important for the video link, could it be that the right side is more for the radio control link?
The goggles are not required for the radio control link, the radio has its own transceiver and antennas to communicate with the air unit.
@@Porksoduh Of course! You are right. I didn't think about that.
He never wrote back to me. Any other way to get a hold of him. I really want the 7ring for my dji v2
I forwarded your comment to him, maybe you can also send me a mail to rcschim@gmx.at so I can forward the mail rather?
normally he's responsive so maybe the mail just got filtered...
The helicals are really my fav antennas - tho I prefer the 3turn since it's plenty range and has a good, wide beam.
And by DJI v2 you mean the googles - and not the "DJI FPV Racer" drone, right? because this would run on 5.8 AND 2.4 and would need dualband antennas (where I would suggest the ORT digieyes v2 as an upgrade).
greets, Mario
@@Rcschim Thanks for getting in touch with him. He sent me an email back explaining that he typed up the message but never sent it. Yeah i figure the 7 ring would work great for my zohd. It is for only dji Goggles at 5.8 and not for the 2.4. I just got a pair of maple leaf antennas for my quad as well as my zohd dart. They work great for flying behind and well as low in tree level. As i watched you test they did get out preformed with the 7ring and 5ring deathray. I hope to hear back about pricing. Again thanks again for reaching out to him about me.
I don`t get why RHCP antennas are tested when the Air Unit use LHCP.
the Airunit in that case had LHCP AND RHCP antennas (that's the config MapleWireless recommends).
Thus I could also test RHCP conveniently. I've been assured that both Airunit antennas send out 100% RF
@@Rcschim Ah okay. But this makes phyiscal no sense to me because then there are introduce crossover intferences from the other polraization. So omnis would be better in this case. There was an Analog system from AKK also with an RHCP and LHCP TX at the same time and frequency and everyone was complaining that this is counter-productive and also makes physically totally sense. The goal should be to have only LHCP or RHCP to have no crossover talk from the other polarization. Also this limit the results on a LHCP-only Antenna set
@@SusiSpecial I also thought that this would be an dis-advantage for the LHCP only antennas - but in my test it wasnt.
In bando-flying with many reflections you end up with L and R RF waves anyways, because every time a signal bounces off the wall it changes pol.
in this test I just wanted to treat the MapleAntennas the right way (as the vendor suggests with his L+R tx antennas).
To me it showed that this didnt give him any benefit.
I just didnt have the time to drive down there, swap TX antennas and up again (20-30mins lost).
Sunlight is very scarce in my sparetime now :(
Anyhows, I think we can conclude: with somewhat decent antennas (like the iFlight for example, or the 3Turns) I get really good and consistent range and signal for me to fly very confident around - explore, fly between houses, behind even...
I tested the mapplewireless omnis and they aren’t really circular so rhcp/lhcp won’t matter much.
awesome but no xair
where to get the 7 turn deathrya ??????????????
As in most my tech videos, there's extensive info in the infobox below the vid!
►HENRIK's "Death Ray" Helicals
To order or for questions, please email: henrikjaderstrom84@gmail.com
He makes those antennas by hand and only sells them via email contact, no webshop. But he's a great guy.
One thing tho: I'd re-consider the choice and rather take the 5turn- 7turns are really long and not so practical. I'm totally ok with using just the 3turns. (and they are nice and small)
@@Rcschim yea the only reason I asked here its cuz he didnt answer my email....so basically no other way to get them.. :(
@@xoasted2919 you can also try to reach him on facebook, search for Henrik Palmroth Jäderström
I said some time ago I will take a look at Prodrone products. Here is a video of a short test. 25mW, I turned back at about 2.1km as I wasn't comfortable flying over a forest.
Here is a short test with DJI Osd embedded for comparison th-cam.com/video/SSbLVqNoniM/w-d-xo.html
Is it dji goggle v1? I ask cause v2 use antennas the different way.
It's the V1 goggles being used here! I'm not sure if V2 goggles in V1 mode would work differently! I know that they do in V2 mode (in the occusync3 DJI FPV drone mode).
@@Rcschim they would, cause they use 2 antenas for RX, and 2 for TX
@@Rcschim anyway, thanks for video! Very useful
@@plugngluck was this confirmed somewhere? Maybe there is a misunderstanding about V1 and V2 modes (software) vs V1 and V2 goggles (hardware)
Because I could imagine, that V2 goggles in V1 mode work exactly the same as V1 goggles (in terms of antenna usage).
@@Rcschim I mean exactly hardware difference. MadTech had video about it. I’ll thy to find
