Please use the fpv footage, unless you are reviewing a gopro. The osd is more important than pretty footage.
11:03 thanks for including the DJI stock antenna goggle feed for comparison
This looks like red rock open space in coso, looks gorgeous! Thanks for the tips!
Hold up... Are you NOT going 6km on the stock antennas already? I put away the patches I had and only use stock antennas and will do 5-6km just fine. Only my battery is limiting me currently. On the drone you should be using either the DJI stock o3 lollipop or the FlyFishRC o3 long antenna. If you are using SMA adapters then you will be losing some signal, and if you don't use the orthogonal linear antenna then you lose out on MIMO gain. Cheers!
Same here.
I sold my patch antennas again because they did not really increase the range compared to the stock antennas.
I'm going 3km with trueRC patch at 30M with 50mbps :-)
I'm getting over 100km on the stock antennas
@@jorisbonson386?
Reading some of the comments I'm surprised how many people dont seem to know how antennas work, dont mean any disrespect, just surprised they don't know the basics.
how do you not get stressed out with the land now warnings? i know liion can go much lower in voltage, but that was kinda sketchy to me.
He-Lick-Cal. Like the Double Helix of DNA. It's a spiral. It's not Hella-Cat.
My 03 air unit goes orange at the bottom way before my TBS Tango and nano RX ever lose signal and I’m in the blue ridge mountains.
Top antennas transmit. You shouldn’t have unplugged the antennas with the goggles powered on
Im not sure if it actually matters too much
@@Robocopter_fpv my g2s (second hand) have worse rx power probably due to something similar
@@KcCake huh yeah possibly. I think if you accidentally do it like once or twice no problem but if you are doing it all the time it might cause issues.
@@Robocopter_fpv depends how much protection dji put in there. Not as much as their vista for sure. No protection and the vtx would be fried instantly but the vrx would still work
Hmmm. Would have liked to see the OSD for the DJI antenna at the same distances to compare to the helical antenna. From what I understand there is little difference with these aftermarket antenna.
Yep, the OSD would have been much better
Depends on the setup here, if they are linear antennas on the drone and he's using CP antennas you lose 3db if it's CP to CP yes helical will increase signal
Hmmm. The stock antennas are easily capable of 6km (many have flown 10km+) in FCC mode. You'll likely see better performance if using the DJI stock VTX antenna (dual band linearly polarised) than using LHCP antennas on the VTX side, as you appear to be doing. SMA connectors also create insertion loss.
True that an adapter will cause loss, but it's been shown that it's marginal, though there are some cr@py adapter that do have more loss.
@@ugpfpv361 Agree that it can be worthwhile, although most of the adapters used on FPV quads use thin, low grade coax with high loss at 6GHz
@@earthsgrip yeah depends on how high gain the antenna are and if it's offset by bad adapters, I've got an antenna vna and have wanted to get some adapters to see what the reflected loss is and compare it to the antenna gain, I'll have to get on that... I'm sure a 10-11db gain antenna would still give you plenty of gain after the loss
@@ugpfpv361 I appreciate you might run a 10dBi antenna on the ground side, but on the air side? High gain antennas are rarely used on the air side because the radiation pattern is impractical, and SMA adapters here are typically causing loss that is not recovered by antenna gain.
But yes of course in principle antenna gain can outweigh the insertion loss, it just usually doesn't happen in practice on the air side.
@@earthsgrip oh the air side, no I was just taking the ground side, yes lots of air side antennas using that crappy coax cable, not to mention ufl... All the more reason to have higher gain on the Rx side
Any sensitivity to which way your head/antennas were pointed? I would expect the signal would fall off quickly if you turned your head slightly away from the direction of the quad.
haha prob not, that signal is goin everywhere including back at the person that's the scary part
They are only 3,turn helical so the cone is not that small, if it was 7 turn or something then yes you have to pay more mind on where your head is pointed
@@adamvalencia1413true but they are directional so they don't only shoot back and to the sides a fraction of what the stock antennas do... So yes you have to be at least pointed in the direction of the drone if your doing longer range
@@adamvalencia1413as a giant sphere of wave data?
Nice video dude. The camera footage is lovely. Did you do any colour grading?
What was the cell voltage when you returned?
Good question

i'm Glad you use ORT from Indonesia
very good for doing long range flight..i use that too, with ORT helical 6 turn..
🤙🏽🤙🏽
Low battery?
When I see one of your beautiful videos I wonder wether it looks the same when you are seeing throgh your goggles. Does it match or is the final video after being uploaded to your computer better looking?
Well, I managed easily 8.7km with exactly the same setup at the beginning. I also fly in Europe, i.e. in the CE area. That means the transmission power is limited.
The DJI stock antennas are great!
8.7 km in CE? Wow …
@@levin7993yeah I'd have to see a video of that, and on a drone not a wing
@@levin7993 I definately cannot believe that range, at all

@@Moroder_Dronei made a video about this topic... it is called: range test, about 2 months ago
Could this be used with the avata 2?
it should work
yeah but what is the point, when are you taking the Avata 2 6km away? I could see it on an Air 3 and up. I have taken my mini 4 over 5km away and had no signal loss at all. I came back from there because I was coming up on a major highway I did not want to cross that far away from me.
@@NewbieDronePilot-ep6og avata 2 drops signal behind objects just 1.5km away 😂 6km would be dream lol
@@chamaldealwis9 He did line of site, yes behind objects you will lose signal. It would be awesome if we could go behind buildings but we can not.
@@NewbieDronePilot-ep6ogYeah so I was wondering if this would improve those situations
Danny Mcgee, you said you should always keep in eye sight where you are obviously so drones van cone back to you, but if you're lost is there a GPS mode to retrieve it back to its starting point?
hi, what i dont understand is that your using 2 5.8ghz antannas on the o3 and using the dji fpv controller 2, which needs both 5.8 and 2.4 antenna, if it looses signal on 5.8 it switchies to 2.4ghz , but in your case if you loose video you also loose control link, plz correct me if i'm wrong.
if your using the dji controller 2 i think it will me more safe to use a long single antanna 5.8 and 2.4?
Old post but still wanted to answer in case you never got to the solution, The O3 unit only works with 5.7 and doesn't support 2.4 so once it drops the rc kinda dies as well. only solution would be custom elrs and a different RC
Is it possible to change the antennas on DJI Goggles 3? If so, would these antennas be compatible with the Goggles 3?
I would like a video were you explain and show the editing part of all your videos, i got material but have no clue how to make/use LUTS or anything like that. Would love a video about that! 🇸🇪
How did you manage to return it back? I was way more worried about the battery hitting 3.3
Li-Ion battery, they can go down to 3.0
Lion you can get down to 2.5 under load with good quality ones
Thank you! I’ve been missing this data.
that is crazy Danny. you now look like a Cyber Rhino Lol. awesome footage
What about for DJI goggles 3. Can I use the same antenna
No
When can we get our hands on those ?
In Europe we are limited. So if getting these will if help? Was thinking of getting into long range. Danny good video as always. That drone is sweet seem to fly great ?
Wdym with limited 😅🤫😏
Hey, I reached with the Goggles 2 and stockantennas + Moz 7 over 8.7km. And still had above 7mbps signalstrength.
(in Europe, without FCC hack)
If you start with long range, I would recommend the Goggles2. Then you could first check whether you actually need improved antennas...
DJI is subject to legal regulations on how much electromagnetic radiation may affect your head / brain. You might get brain cancer or Alzheimer's disease. I would always make such amplification modifications externally on a tripod, away from the body.
You know the biggest source of electromagnetic radiation?
Be careful using dji rc link it shares power with the vtx and can cause failsafe if the vista or air unit needs the power
Work only with g2 ? Or integra too ?
Why are you not concerned with low battery message?
Will these work with the DJI goggles 3
No
Hey Danny, Thats amazing footage and range. How do you connect the DJI controller to Quad? ELRS?
O3 Air unit has rx
@@koalafpv Thanks for the reply. Can you send me the instructions on how to connect the DJI controller to a regular ELRS?
@@ronboFPV that’s like trying to make an elephant speak english. Not possible. It’s 2 different languages. You need a radio with an ELRS Tx to speak to an ELRS Rx
@@koalafpv I'm confused, How did you connect the DJI controller to your quad ?
@@ronboFPVI didn’t because I fly analog and crossfire lol
What antenna on the drone ?
Doesn't it have to be line of sight? Oh, you don't live in the US do you?
I wonder how low voltage the pack was on arrival
me too
Nice scenery. Where is this?
Are you flying 700+ meters above ground?
Fucking love your content man! ✌🏻
Thats my country build ❤❤ thanks man
It gives me anxiety from 9:26 😮
Awesome Flight
Antennas! OMG, who would have known?
Secret? What kind of secret?) Helical antennas?)
Just thinking out loud but I wonder what the health effects of having an antenna that strong against your brain bucket will be. ...if there were ever a time for a tinfoil hat...this might be it. lol
What he used are high gain receiving antennas. This means that you can simply "listen in" better to your video signal. You can think of it as having a bigger microphone to pick up the drone's VTX signal, not a big speaker to talk to the drone. There are no health affects to using such antennas.
The radio controller on the other hand would be the thing to look at for health effects, it's the one transmitting at one or two watts of power potentially. (Spoiler: it also doesn't do anything to you.)
@@melon9088agree, but the goggles do actually transmit also, same as walksnail
Lol!
that place is beautiful, where is it? US?
using the dji controller for long range lol nahhh im good. if you lose video you'll lose rx aswell thats a solid nope for LR flying in my books.
Never had that issue with my set, try it by yourself, u can still control the quad when googles are off, I learned that in the wrong way, my goggles battery died in a middle of a flight
@@Marcarfel yeah nahh I know how the radio link works I'm not gonna try it for myself thanks LMFAO 🤣
I also used the DJI controller for a long time and never had any problems... I even managed 8.7 km distance with it 👍👊
nothing new here :P and if you are a DIY guy, you can do them yourself too :)
ORT from Indonesia 😍😍
bro is at 4km away with 3.3 voltage is making me nervoud
nervous*
Could these be used with dji googles 3
Goggles 3 can’t pull the antennas out.
"amplify the signal from your goggles" uh,, what?
Spoiler alert: he dumped Frsky, and installed Crossfire
Should have got the 6 turns
It's pronounced "he-lick-al" it's the geometry of the antenna
Im sure everyone would say its a "safe" level but id love to measure the amount of radiation going through the brain is with this... its can't be good... this might be an actual real word use for tinfoil hats lol
You have no videos to present
present what? I said id love to, haven't done it yet but you can read about radiation effects on the brain from almost any prestigious college there's a million of them, and deductive reasoning while something in large doses can kill you the same thing in small will not, and labeled "Safe" to protect the free market and not outlaw the millions of products that cause cancer and such but still in small does isn't good. if you live in California you would see alllll the products that's cause cancer and reproductive harm, almost all plastic products have that label on them in ca even fast food. its legal to sell and "safe" yet still causes that as stated by the warning labels... sooo I mean it does obviously cause harm the question is hoe much...
Your phone is doing way more
@@Krash_fpv you are also using your phone for it plus the antenna on your head.. those are much more powerful antennas and a google search shows it uses 3x more than the average phone plus the phone so its like having maybe 4 phones strapped to your head, also phones have radiation caps in most places by law... these have none and are most likely capable of producing much more than they already do, depending on what they are doing or updates...
@@adamvalencia1413because it's a directional antenna it's actually less signal "shooting " into the brain than the stock antennas, in fact even higher gain directional antennas would even have less signal shooting back
🇮🇩 Indonesian 🔥🔥🔥
Emph"a"sis on the wrong syll"a"ble
Why am I panicking on your behalf seeing the battery level at 3.28 while you are still insisting on flying farther and farther?? 😂
Lithium ion can go down to 2.5 unlike Lipo 3.5
@@huzafah_ I see!! Thanks a lot for the info!
@@rasheedalrashedi yes.. everything is everywhere. A definite rabbit hole i’d say 😂
Truerc x -air 20km easily with o3
Helical's? Thought everyone knew this ya pretty old hack at this point really. Nice job though
ORT 6 turn is better
And a 12 turn is better than a 6 turn ...
Antman😂
You were at 3.4 volts and 4.2 km u must be on lithium ion packs
Yes that's what he said in the video
boring
👍👍👌
But the dji is 999 and can already go much farther than 6
But today the real serious fpv Is made by other companies, not by dji
He meant sixty kilometers
@@abinjohngeorge_07 no dude, di VTXs could reach a maximum of 10 kms
DJI might not be able to even fly soon
@@john-martin only in america
Omg 😂😂😂
Crossfire 2W will literally go miles farther that your set up. BTW. Range up to 50 kilometers Range. For long range the DJI controller is not recommended.
flew mine on top of a volcano 5km away, with just DJI RC2 and Integra googles, been flying long range with micro using dji controller 2 never really have problems . here see for your self th-cam.com/video/AO-KeshhK-0/w-d-xo.html
Crossfire is analog tho
Laughs in ELRS... 50km...
I'm totally with you on the DJI controller tho...
@@nevezeraayou can run an O3 air unit with crossfire
Elrs hehe crossfire don’t do updates so good look supporting that protocol
It's good to see you take steps to have proper long range equipment. Some observations:
3.,4v at 4km is worrying, it means the quads is too heavy.
The motors running 7537 has to work VERY HARD to carry that weight over that distance.
Ideally it should be heavier in pitch, at least xx50-xx60 to carry that weight for an efficient cruise.
Probably you'll change out the VTX antennas, and you should get more range than the DJI controller.
You did see that he took off at 3.8v right ?
do you know what a lthium ion battery is (they have lower voltages) he also told us that it was configured for smaller lipo battiers (Not lithum ion)
DJI RC is the biggest dogshit I've ever seen. Just use crsf its a bit more expensive but so much better. Also any crsf or elrs radio can do 1000% of what the dji rc can.
dude you can go 6km on stock antennas?
6 km is not long range, that's mid range. 30 km is long range. I mean, any 03 or 04 unit will go 34km out of the box and even an avata 2 can make it 5 km and back with ZERO modifications. Sorry but 6 km is NOT long range anymore.
6km is definitely long range in the quadcopter fpv scene
💀💀💀💀
I’m pretty sure the 03 cuts out at 13km whether you have signal or not.

Hi i am new to fpv i will love to start fpv ,but i have a futaba 14sg can this be used for fpv, and what should i get.
I built one of thoose helicoidal antennas when i was 14 , costed me 2€ and still works , one of the best antennas i have
I've seen some of those helicoidals for sale for OMG prices. To be honest the one I saw looked like it cost under 5 dollars to make yet the price was $700 and others went to prices well over 10k obviously these were for different purposes than drones but still!Shure HA-8089 Helical Antenna for Wireless Microphone and Monitor Systems (480 - 900MHz)

Great video! Why the switch from iFlight to Geprc?
old skool helicals
6km only ? lmao
Geez, I would have thought with the FAA rules in action, nobody would do any range tests anymore.
Especially after Wesley Fargy got in trouble with the Aussie government
But thank you, for the test, it is always great to see how far equipment can be pushed
Yeah, guess it depends on which country he claims to be in, and technically in the USA you can get a waiver to go beyond line of sight with the proper conditions
Its all some bull shittt
I have the DJI Avata with the DJi googles 2 and the DJI controller.... Living in Spain....
Do you think these antennas will work and that I will notice?... my range is very short and I keep on looking for the signal instead of controlling the flight!! And that is dangerous
Helicals lol aint rocket science LR pilots been using thrm for years you can even make you're own...
At least here in the usa it's pronounced Heelical... And where is the 6km?
10th!!!
plz pin
great video..curious why aren't u using these antennas in your more recent videos.. looks like u went back to the stock dji antennas in those videos. what made you go back?
stick error 😅😆 they say if you loosen it a little it won't have that anymore. Also I heard if you use dji controller with the 03 and you lose signal you can't gett it back or something fucked up happens I forgot what exactly but it wasn't good.
Yeah it has to be power cycled
power lines block part of radio waves
where is you donate button?
This gave me anxiety.
I need to look in to this. Great video as usual.
❤❤❤😊😊😊🎉🎉🎉
Would it work with the googler 3 + avata 2?
you cannot pop out the antennas on g3
I thought there were receivers that used the cell tower network. Why not just use that and you would have infinite range?
Latency
@@ugpfpv361 Ahh….
Dustin Dunnill did a video of using LTE network to fly in his Parrot
@@rubengarciajr7560 yeah that was a while ago, with something like a wing I can see but for a drone doing something like driving mountains or flying closer to the ground, the latency is not low enough, pretty cool though
6km out is no problem with stock DJI. These antenna will be better for like 10km or more
He showed at around 2.6 with stock he was getting orange signal display
@@mrantssfpv yeah, but a lot of us are already going 2 to 4 times as far on the stock o3 setup (on drone and goggles). DJI already did a great job with their antenna design, idk if any of us are going to improve on that using trial and error tests. The flyfishrc long o3 IS better, but it's exactly like the stock just longer.
