My test-setup:
I use 1mW on the transmitter, 10m distance to a VERY SENSITIVE receiver (Aaronia Spectran HF6065 -150dB! • Aaronia Spectran HF606... ) and take enough samples to get an average.
I measure antennas in their best orientation (vertical for omnis) and the worst (antenna null point "above" the omni antenna).
Fun fact:
As my test suggests that Lollipop 1 is better than 2 and 3, here I read that Lolli1 was PCB style (like Lumenier AXII) and 2 was spw style. That explains why the Lolli1 was their best antenna - because they cloned a good one :)

@@pusico6555 MMCX: Hi, not neccesarily bad. if the quality of the coax cable is ok, it should perform just fine.
It's not so easy to test different antenna connections. Especially UFL I have no adaptor for.
but even for the cases where I have adaptor cables: they alreday influence the measurement....
So I would need 3 exact same VTX with just different antenna ports ;) but then again I couldnt be sure that all those VTX would be build with the same quality...
Great info as usual Mario. I'm working on a similar (albeit less comprehensive) antenna comparison where I'll be providing information that supplements what you've done (I won't be reinventing your wheel). I'll look at beam-width and axial ratios which are also important factors in antenna design and something that is often overlooked. If you're flying analog FPV, axial ratio is especially important because it determines how effective an antenna is at rejecting reflections.
Cool Bruce, cant wait to see your findings. Have you noticed the nice irony here: Foxeer L1 was the best (because it was apparently a clone of Axii) and the newer ones were not so good? I had some doubts with my measurements first - but now it makes sense :)
About beamwidth, SWR and Axial: great idea! One commenter here asked about SWR and the impact. Alex Greve of course knows a thing or 2 about antennas and tested it nice: th-cam.com/video/XCFul9qxvjE/w-d-xo.html
I dont have an SWR meter yet (not sure if the cheap ones are good?) but axial ratio is probbably not so easy to measure?
Curious how you test the beamwidth. greets, Mario
British guy does this test : flies it down t' street.
German guy does this test : sets up an array of technology.
Reminds me of the Rocky vs Drago training montage 😅

Thanks, always try to catch the viewers eye without clickbaiting (I'm over this) :)
@@Rcschim ^^
AWESOME job at testing so many antennas, with excellent data analysis and interpretation. Thank you for your hard work and the very important information that you provided to the FPV World. I found your channel by accident, and I'm glad I did. The information you provided will change the way that I select an antenna from now on. No more trial and error, I'll just review your data and find the antenna that best suits my needs. I hope Everyone in the FPV hobby/sport will also be able to find your channel as well. I will definitely spread the word about your channel.
Thanks Conrad, awesome comment as well! It's quite a heavy task to test antennas this way, but I wanted to know for myself how they compare to eachother. Since I almost exclusivly fly with DJI FPV now, I rather thest antennas in that application - and there I measure the resulting Bitrate (which you get in a logfile on the goggles since it's digital). Check my newer videos if you also use DJI antennas - quite some interesting findings there. greets, Mario (and thanks for spreading the word about my channel!)
Thanks for taking the time Mario.
Was using Triple feed patches on my Fatsharks 2km out yesterday on an epic flight. Then low batt and loss of sight of landing area disaster, yes I lost it! Search begins 300kms from home next week LOL! 500m x 600m search area on steep tree sloped hill.
aww, that doesnt sound good. Hope you find it! Do you have DVR rec of last seconds?
lately I have little "tile" blutooth tokens as model finders. They are limited in range, but sometimes you walk past a small drone when it's only a few meters away...
@@Rcschim Thanks, pretty small area I came down in maybe 2 football fields and I saw a close by fence that was near so it should be waiting for me but no dvr no tile and I could not hear beeper or see vid signal after crash so I'll make it a day trip search. :) the footage was my best flight to date.
I've noticed a lot of people like using TPU mounts for vtx antennas that partially or fully cover the active element with TPU. I read a comment from Martin Baert where he stated that TPU has a relatively high dielectric constant and so shouldn't be used as a protector around an antenna active element.
Maybe you could do a controlled signal test with antennas in and out of TPU mounts to see if there is a real world difference?
Tbs triumph is still working for me. Actually thanks for that great effort, I can’t imagine how it is to test and not to mention analyse all this data for us.
Watched this twice now. Amazing work. Thank you so much for this.
I cannot believe the spironet patch did so well. This is absolutely awesome work! Also, this seems to verify that the DJI antennas are intentionally garbage...
Thanks and nice to see you here. See - my effort to share this vid on my almost abandoned facebook paid off at last :)
IRCs little patch was always a fav of mine. They still fair good. But the weird shaped OrqaP1 is also decent.
My measurements with the DJI antennas were not 100% fair tho (once again pol mismatch although this doesnt seem to matter much here).
Next I wanna see how much loss we have if we use pigtails (mmcx-sma) on the copter - or 45°sma adapters on the goggles. MenaceRCs measurements imply that we loose quite a lot there. I thought it's only a lot of loss on really long SMA cable extensions... greets, Mario
Thank you so much for all the hard work you do testing all this, it really is a great contribution to the hobby!
Wow 😳 that’s a lot off effort my friend thumbs up 👍 keep it up cheers 🍻
Dude, this is incredibly helpful! I'm really happy about guys like you putting so much efford into giving us an orientation what to get to actually improve our situation. It helped me out quite a lot.
Thanks, comments like your's are really a good motivation to make the next review / test video. Stay tuned (or just sub/bell ;)

Excellent review Mario. Thank you for doing all this work for us!! Very interesting results in some instances!
You're welcome!
RCSchim You are just plain GOOD ! That was a Great Video ! Thanks !
You’re the best my friend! Always great contents in your channels
Thanks for nice comment!
You made me think of a question. How much do the insertion losses affect performance between UFL ipx, MMX and SMA connecters? They may be negligible. Thanks.
As all questions are always welcome - this is a really good one! It lead me to this post from menace: menacerc.co.uk/sma-adaptors-signal-loss-or-not
Check out how much loss different cables have!
I will re-visit my current goto quad - because out of convenience I use a pigtail mmcx to sma adaptor - while I also have Lollipop or SpeedyBee antennas directly with a mmcx connector. I didnt think there would be that much of a difference! Thanks!
Maybe I test this more (like menace in his article) and make a short video about it...
Really nicely done. Thanks a lot and greetings from Vienna! :D
Wow! Amazing work Mario! Thanks for sharing :)
Thanks
Like first then continue to watch
After all these years,IRC Spironet still looks like best antenna combination.
Have you tested any HDZero equipment yet?
Great testing.
nope, no HDZero for me. I would compare it on my spectrum analyzer just out of curiosity, but I'm not the target group for this HD link I guess ;) DJI just works well enough. maybe if I have more time to test stuff I'd get into this...
sorry, greets, Mario
Nice job as always! Thank you very much for the info!!!
Woow good work, thanks for all this effort, all the information is appreciated 👍👏👏
Excellent! Interesting the crosshair extreme did worse this time than previous tests compared to the small patches.
Good finding. Might be, because I used a bit different approach this time. (10m instead of 5m, slightly other frequency bandwidth, more data taken).
Dude. You're a data maniac. Thanks!
you can generalize and leave away that "data" ;)
Appreciate your effort and very helpful information. It will help my future purchase.
First off, excellent test summary!! 2 questions though on the Foxeer Pagoda (ranked #7): 1 - that's the "short stubby" sma at 68mm, correct (not the long version at 86mm)? That's where your link took me at Bangood. And as far as the performance, it doesn't appear that there's a ton of difference between that and the RealACC Red Pagoda? Thoughts...
testing signal-strength on the Eichberg? Does this mean your antennae are now… ge-eicht? (I'll show myself out)
hehe, play on words there eh? Didnt see it that way - but of course you're right :)
Thanks for doing this mate!
This is what I call a test !
Yeeessss, I've been waiting for this!! 🙏🙏
It'd be cool if you picked up some Actuna antennas if you do another round :).
Ohh you have a W124
hehe, it's my father in law, he loves it. Proudly still drives it after over 20 years or more.
Holymoly that is a lot of work! Now I am affraid to ask since that sounds so......you know....anyway, can you test the DJI system? Your tests are the best.....THE BEST! Keep it going
The DJI antennas are included in the tests.....
What do you want to be tested with the DJI sys? I already have a few videos about DJI FPV. Check them and please let me know what more I should test...
And thanks!
@@Rcschim personally I'd just like to know the two best antennas to have and where to put them on the goggles.
I have the lhcp URUAV patch antennas and the menace digi pack also patch but the digipack has two extensions on them as they are supposed to work better further away from the goggles whereas the URUAV fit very close.
Two of these antennas leave me with two stock DJI antennas to upgrade..... Presumably Omni rather than another 2 patches. Which would you say work best for combination of all around flying max 1 mile out in ideal conditions?
for 1mile you can leave on the stock antennas :)
many swear that the TrueRC singularities are good. I wanted to test - but they have such a high backlog on orders they didnt want to send me samples to generate even more demand on their products :)
You could also try lhcp lollies or chep SPW antennas. If you get them specifically for DJI goggles, buy em with rpSMA connector (and watch out for LHCP if you stay with the stock Airunit antennas.
@@Rcschim agree that the stock antennas are good for the distance ... Where I fly I struggle to keep a good quality bit rate hence the interest in other antennas.... I also fly a lot in dense woodland
thanks you man.excelent contribution
From what you have sen with these results. Which antannea would you buy for long range Analogue HGLRC ZEUS VTX 800mW on the quadcopter and on your goggles? The drone has the FrSKY R9. And as an aside, I have found my DJI airunits with the standard antennae on both craft and goggles seems to outperform (distance wise) what I have above in the analogue quadcopter, that has already had a failsafe about 100 meters behind me.
I'm surprised at the stock DJI antenna result given how well it performs in real flight bitrate performance tests compared with many of the featured antennas. Given the DJI antennas are RP-SMA did you use RP-SMA to SMA adaptors? Because using adaptors will actually lower the performance.
The DJI stock antenna test is not very serious here I have to admit. It was the wrong polarization (but in my DJI tests polarisation mismatch didnt alter the results much).
I will test this more and try to give a better image.
I think tho: with 700mw or more, you can mount a piece of wire of your choice (maybe even a twig) and DJI fpv would get usable videolink anyways :)
@@Rcschim Wrong polarisation yikes. Wire or twig lol. 😆 I will await your upcoming retest video. 👍
omg you are my personal hero!
Due to shortages in stock I chose the ORT 6 helix for my semi LR setup. With my TBS Triumpf Long Range Antenna, 800mW output and this ORT I hope to make it some decent 6 km for a first :)
shoratges of your winner the circular wireless antenna
Thanks a lot.. i will try learn how to read it ^^
Was the DJI stock antenna so bad because it was LHCP but the transmitter was on RHCP?
yes and no. In my previous tests with DJI goggles I thought I'd see dramatic drop in performance when mixing pols (pol mismatch) - but I didnt! Maybe it's different in analog application here tho.
I should repeat a smaller test with just a pair of good (potential DJI antenna upgrades) vs the original set (air antennas + goggles antennas - but with analog VTX and my spektran).
RCSchim Yes, please do 👍🏻
you are the best ❤️
The measurement is half scientific, but, sure one of the better
From the spectrum, you have a video cam attached to the VTX, and what is with the ~10 dB drop on ~5,803 GHz?
The RTC705 (VTX) should be able to operate in CW mode (no cam), has a phase noise of ~ -90 dBc/Hz @ 100 kHz offset (good enough to sweep measure with CW)
Combined with the spectrum analyzer (USB control) you can automatize the frequency sweep...
Your measurement is only good as the reference antenna, try to get a reference antenna and a 90 deg hybrid (polarity RHCP/LHCP measurements...)
Comparing gain (signal strength) between antennas that not claim to have the same gain isn't actually fair, of course, an antenna with 13dBi should have a better signal in a "good orientation" than an 8 dBi ...
The really interesting thing is the radiation efficiency and the LHCP/RHCP radiation pattern.
At the end of the day, the best combination is use case dependent (but at least you can pick an antenna with high radiation efficiency and good cross-polar isolation).
Some literature on the topic:

looking forward to your next video!
Wow! Super feedback and comprehensive comment! ;) No idea what the drop around 5.803 was. Maybe a problem on the Spektran? Next time I'll investigate this further (to see if this comes from the clearview VTX).
CW mode just means "black" video (because no cam source attached?). Do you think the image signal noise is already to be seen on the spektran (like if I'd probe the yellow wire of a cam on my oscilloscope?
What kind of reference antenna would you suggest? What's an 90 deg hybrid (coupler?)
You're right, comparing apples to oranges here so to say. But my idea was to show the viewers what kind of difference to expect in real life with different antennas. Be it the same gain and just different results due to quality or different gain and therefore better signal (like nice and easy to understand why 3,6 and 8 turn helicals are better the more turns they have).
Considering all the rules and making this test nearly scientific - would reduce the possible audience to a VERY tiny group of people. So - the more effort - the less views in that case :)
Thanks for the literature - I'll dive into it! Always good to learn new stuff - and RF is definitly a wide field and a lot to understand better for me...
greets, Mario
@@Rcschim Cleare Wave (CW) is a not modulated signal carrier (no camera attached), the difference to the video signal is that with CW you get a single peak in the spectrum (you can sweep in a smaller range)
The problem measuring with a video signal is that you get a high trace noise (your measurement deviation is huge) because of the modulation (without sync to measurement device).
In CW mode you need only to track one frequency (that in ideal case don't change in amplitude and phase) you measurement deviation should get to 1k EUR), so you won't probably by one.
You can also make one by you one it's not that hard (but also not ideal), (waveguide) horn antennas are the best because there have a high performance, for example, efficiency can easily reach nearly 100%
There are also methods to extract the polarization performance..... with unknown antennas but that is a big topic and requires a huge amount of measurements.
So to improve the measurement put on the VTX an antenna that at least claims to have high cross isolation and gain in the range of 6-18 dBi
BR, Tomislav
@@tomislavjukic8362 OK, I saw you're working for orqa - that explains why you know a thing or 2 about RF - and that also explains why their products are of good quality!
So the "no cam" on VTX change should be easy and improve my accuracy on the next try.
The weird horn antenna will probbably exceed my test-budget (anytime a "request quote" sits there right next to a product you know you're in trouble if you wanna get it ;)
What about easier alternatives as VTX TX antennas? What about the omni from orqa (the nice one I got with a disc that is screwed onto a coax?)
Or what about a simple Linear antenna?
@@Rcschim
No, the Omni has a too low gain. You need a directional antenna, your goal is to characterize the antenna, not the surrounding (reflections from the ground, walls ...)
Found some:
-KIR-6050 antenna
The drawback is that it has only one polarization (linear)
-KIR-5800DP
Can be used for linear and circular (requires additional equipment) polarization measurements.
These two should have decent performance and don't cost too much.
Great test! thank you! could you add a picture to recognize the small pagoda RP? also what about lumenier AXII patch and omni? I know they have a big name out there
Hi, yes - I did - hope you can recognize it. Look: I remembered that it must have come with the Furibee X215 quad I reviewed a long time ago: th-cam.com/video/Hvunm4gJcRs/w-d-xo.html
Here's an even better pic: des.gbtcdn.com/uploads/pdm-desc-pic/Electronic/image/2017/10/12/20171012184243_26450.jpg
I searched "pagoda 2" on gearbest and came up with this: www.gearbest.com/antenna/pp_635516.html?wid=1433363 hope this is the one.
Have no idea why this did so well in my test. Maybe the cable is just the right length to get some reflection from the spektran. I can hardly believe that such a cheapo pagoda would be really so good :)
@@Rcschim Looks pretty different to me.. Interestingly the photos of the Furibee X215 now show the antenna that you found on gearbest.. So maybe they changed it in general?
Du kannst sicher spitzen cb funkantennen bauen😁
a lot of work and effort went into that thanks for that.
i have a question what effect does the swr have on these results? i have had two of the same antenna with different swr.
I could try to explain what SWR is - but there is one guy that really knows what he's talking about: (ibcrazy)
th-cam.com/video/XCFul9qxvjE/w-d-xo.html
I think poor SWR is effecting your range, bad axial ratio effects your antennas ability to be "immune" to reflections (when flying near objects, low).
@@Rcschim thanks for the reply, love your videos, no i know what swr is, but what i am saying is did all the antenas have the same swr ?
@@stevemann6082 That's of course a valid question. I could only answer this if I convince myself that I also need to spend some cash on a SWR meter :)
So, which omni antenna to pick? and directional? Any advice?
great job !!
are you going to test the omni prodrone antennas?
Once again I will now write to a few shops and manufacuteres and ask for review samples. If they send stuff, I will make a 2nd video like this.
Prodrone has been mentioned a few times now - they should answer your calls!
greets!
RCSchim ok cool. And for the dual spironet LZR-13 patch ? You do some test ?
My Kwad does 5 km omni with the old blue naked Aomways, i use an extension and a TBS pro32 HV.
sounds more than enough for a quad. do you use RTH GPS or just fly risky on the edge of your range? I always get nervous on suboptimal image and therefore never reach the real edge of my setups range ;)
@@Rcschim INAV und RTH und dann nur dort wo ich mich auskenne sonst ist das zu heikel. Leider funktioniert das aber nicht immer obwohl ich das setup nicht geändert hab, gestern warens nur 3,5 km. Man sollte das Handy gar nicht erst mitnehmen und ich glaube die Wetterlage spielt auch eine Rolle oder bilde ich mir das ein?
@@BBFPV Die Luftfeuchtigkeit spielt definitv eine Rolle. Handy kannst ja in Airplanemode versetzen, oder zumindest WLan und Blutooth aus.
Du meinst RTH funkt nicht immer? Scheint generell bei inav aber mehr noch bei BF noch nicht so gut zu funktionieren bzw. gibts viel zu viele Einstellungen. Nurk FPV hatte zuletzt dann mal einen Erfolg - BF GPS mode geht endlich bei ihm, aber da waren einige Einstellungen nötig....
@@Rcschim Nee ich meine 5 km zu erreichen funktioniert nicht immer. Mit RTH hatte ich weniger Probleme, man sollte den Copter erst aufsteigen lassen und bei INAV ist der Rückflug etwas ruckelig, ich vermute er korrigiert alle paar Sekunden weil die GPS und Magnetometer Daten nicht ganz zusammen passen. Ich hab das BN 880 drin und musste es als upside down und mit -270° konfigurieren sonst arbeiten die gegeneinander bzw. er fliegt seitlich nach Hause. Vermutlich stimmt die mag. Kalibrierung bei mir immer noch nicht ganz. Im Flächenmodell klappt das aber sehr gut, neulich ist mir das Bild der Split eingefroren da war ich froh ihn bis auf Sicht heim holen zu können.
@@BBFPV OK, beruhigt mich ein wenig. Hatte bis jetzt nur mal kurz mit dem SG325 Skystars? Kontakt mit iNav auf Copter. Den muß ich eh mal wieder verwenden (bzw. evtl. auf Caddx und CF umrüsten. Weißt nicht zufällig ob iNav auch schon mit DJI "spricht"?
Die 270° musste ich glaub ich auch beim SG325 einstellen.
Und ja, der Autopilot ist ein wenig wakelig... Ausserdem hatte der Copter auch Motor-Desyncs glaub ich - also noch nicht ganz vertraunswürdig.
Flieger und iNav würd mich eh auch reizen, MiniTalon z.B., aber da fehlt mir immer wieder die Zeit...
Have you tested an AXII ?
Thanks for the test. What do you currently actually fly on your DJI HD setup (top and bottom) for long range?
I have the feeling that I could even use my normal setup (4 Foxeer Lollipop, non stubby) for Longragen :)
But to be safe I use 2 patches on the bottom.
If patches belong on top or bottom is an ongoing discussion - I should do an extensive test regarding this as well.
Bardwell will test new antennas soon and maybe he can find out more bout this...

Vielen Dank für deinen Test!
Kannst du mir sagen, warum die ORT Helix 3 einen Gain von 7 hat, dann aber in der "guten" Richtung besser abschneidet, als die VAS Crosshair mit einem Gain von 10?
Suche nach einer guten Long-Range Patch/Helix-Antenne, dachte eigentlich an die VAS Crosshair, bin jetzt aber etwas verwirrt.
Hi, in der Theorie sollte die Crosshair schon super sein. Stimmt ;)
Vielleicht ist mein Test-Setup für direktionale Antennen nicht gut? Vielleicht kommen die Unterschiede besser raus, wenn man RX und TX viel weiter auseinander hat (für die schwächste Antenne an der Grenze) - dann wären die Messungen vielleicht genauer.
Dennoch dürfte wohl die Crosshair nicht schlechter abschneiden als die Helix. Für Longrange würde ich aber sowieso eine Helix nehmen.
@@Rcschim Vielen Dank für deine Antwort!
Jetzt weiß ich aber immer noch nicht, welche ich nehmen möchte. xD
Die 3-fach gedrehte Helix ergibt im Gegensatz zur Crosshair also nicht so viel Sinn, es sollten also mehr Drehungen sein? Gibt es da eine Helix, die man hier aus Deutschland bekommt und unter 50€ ist? (Deine Tabellen habe ich mir angeguckt, bin mir aber noch unschlüssig)
@@mryolp3462 Kommt die Helix dann auf die Brille oder doch Diversity Groundstation?

Geez that’s a Ton Load of antennae👍
Yes it is! And my test help me as well: normally (and this is the situation since a long time now) I go fly, see what I wanna pack - then I come to antennas: which one do I take today? Is it really the best choice? Now I have hard facts :)
RCSchim REALLY appreciate all the work you put into this testing, I have the Circular Wireless Helical it is an outstanding performer. I’ve come close to FAILSAFE with that antenna, because the video is really clear at distance, and I forget to watch my RSSI 😂
I pretty much use the Blue Aomway and the Foxeer Echo.
@@WildCaptures Blue Aomways always worked fine for me (I'm surprised that I didnt test the blue spw as RX (it was on TX) - think I forgot it at home.
Maybe you should replace the Fox Echo tho - I dont think it's a good one. Maybe a Menace pico?
On the eichberg😂😂😂😂
you just cant beat these kind of tests,
since you ended your sentence with a "," I'm waiting now for you to continue this comment (waiting 11hrs now!) :)
@@Rcschim hehehe, i was just leaving it open for a reply, although i was gonna mention i was just rewatching painless360's vids with the menace rc guy on antenna tuning and the other one about tpu covers affecting tuning, just research to check my aomway/eachine ev800d stock antenna to see if theres a '' best channel'' with the combo...
The name "Small pagoda RP" doesn't exist..??
are you using adapters for the foxeer antennas on the dji fpv? because all are sold with rp-sma male connectors, thats the same, that the dji fpv google use?
yes, I ordered a few of these here: bit.ly/2CpfhHy
they let me use my SMA antennas on DJI goggles.
Of course I also swapped the Antennas on the airunit to be RHCP instead of LHCP
RCSchim Could you post a picture of your setup? Which antenna did you put on your air unit? I see the Lollipop 3 is available in angled sma (10cm) ?
sub..very useful..god bless you sir...thanks..
hi mate, im beginner i wanna buy antenna for my google, wht best combo antenna ? thankyou
Hallo aber die VAS Extreme Crosshair (bottom) is ja RHCP und bei DJ die Stock antennen sind LHCP . bei einem iflight copter sind auch stock LHCP drauf . muss doch einen unterschied machen oder .
Was ist jetzt deines achtens nach wirklich zum empfehlen für die dji brille wenn man ein bissl Long range bzw Bergfliegen will . Welche antennen wie angeordnet . lg
Ich verwende rhcp auf copter auch.
2 normal omni zb Lollipop oben, und unten 2 patches. Demnächst teste ich 4 Helix auf einer 3d gedruckten Platte, könnte auch ganz fein funktionieren.
De Version für rcschim wäre fein, ist mir aber grad zu viel Arbeit. Aber danke fürs Feedback!
@@Rcschim hät auch grade gehört das in einem fcc dokument steht das eine antenne unten nur empfängt und nicht sendet . von dem schon einmal was gehört ?? is da was wares dran ?
@@SteirerBUAH www.dropbox.com/s/me0fdl1stkozukw/Goggle%20Antennaports%20info.jpg?dl=0
hier das Bild schaut interessant aus. Wenn Du die Brille auf hast, die unten links ist nur zum Empfang, alle anderen senden auch.
@@Rcschim jo genau also grad anders rum . Jo i hab des grad in einer whats app digital gruppe wo eh leut von deim nachbarsort drin sind gehört . Wusste das auch nicht !
@@SteirerBUAH fpv und blabla Wu meinst? Da war mir zuviel blabla ;)
If the DJI stock antennas are so bad, why is it there's no conclusive evidence that other omni antennas on the goggles give better performance? From what I've seen, the DJI antennas mysteriously perform as good (or better) than any aftermarket omni's on the DJI system.
did you miss my DJI antenna test videos? there are enough hopefully conclusive hints how moderate those stock antennas are (on purpose per the FCC rumors).
Check this data comparison public.tableau.com/profile/phi2340#!/vizhome/RCSchim-AntennaTest_15966376169330/AntennaTestDJI
and just click the 3x DJI antennas symbol in the right. Then the performance of DJI antennas is highlighted while you see all others in the back. All of them are better :)
@@Rcschim Thanks. I saw your videos but did not see the chart.
Is it a fair assumption that putting these antennas on the DJI air unit itself would be a good solution as well?
yes! definitly. I'm not sure about the original UFL connected caddx vista antennas - they might actually be good.
But the DJI airunit stock antennas are small and limited. Just swapping them even to the worst lollipop gives me better range.
and if I swap the AirUnit antennas - I also change over to RHCP (stock is lhcp) this way I can use my normal RHCP analog antennas on the goggles.
Which one ur recommendation for below 1500meters on micro/tp3 with 600w-1000w vtx
If you check my description I give recom. to which antennas I currently use on DJI fpv (after testing).
Lolli1 (or Axii from Lumenier)
Orqa P1 patch also quite nice.
In reality, if you have a good old IRC 8dbi patch - it's also quite good. The VAS extreme crosshair is also good, but a bit expensive.
and with 600mw (I hope you meant milliwatts and not 600 watts :)
you can use any omni antenna and be good.
@@Rcschim oh nice. Thx for really good info and so much works has been done. Much appreciated and stay safe sir.
Why didn’t you take the 190e?
It's not mine :) It's the proud of my father inlaw. He had it for decades and it's still in good condition.
First 👊👍
One dislike from an Eachine engineer..
I wish I would've seen this 10 months ago lol OUTSTANDING DATA!!!!🤌 I'm new to fpv however I have been flying drones and planes for over 20 years and I'm a rc hobbyist at heart!!!! I have always been more of a land vehicle and plane guy not really into boats however when drones first came out I had to have one and give it a go lol helicopters are kinda hard to fly but having the experience helped me alot with flying drones....anyhow I have been looking for the best antennas I can get for my fpv goggles and since there are so many out there it's hard to decide....then I seen this video😍 lol I'm absolutely shocked by the data !!!!! I mean who would've thought that dji antennas aren't that good lol I really thank you for sharing this data and especially since it's for both polarized and patch brands👍 looks like I finally found what type of antennas I'm going with😁👍✌ and I am definitely a sub now great information man ✌💯
Thanks for your nice comment! A few weeks ago I got an even more accurate RF measurement device - hope to make even better videos in the future with it! greets, Mario
@@Rcschim I can't wait mario👍 you have the most accurate and from what I have seen the best data information on all of TH-cam!!! I am looking forward to seeing your future vids✌
