- I tested if the parabolic Reflectors or the yagi antennas add more range to the Mavic mini. If you’re looking to get your own here’s a link to each that I recommend
Double Up (FCC 5.8GHz) ! amzn.to/3mTO6sg
Yagis (FCC 5.8ghz): amzn.to/3zG61KW
Parabolic Reflectors: amzn.to/3zL6N9v

I'm a ham radio op. Yagi's are great antennas for gain. Also, extremely directional with a strong front to back ratio. And somewhat of a tight beam, so you would have to keep them pointed at the drone all the time to get the best possible performance out of them.
Just info for anyone.
@BenBenson The separate elements in a Yagi antenna are not electrically connected. It's the spacing and the length of the elements that matters.
You have a driven element, then on one side a reflector element that's a bit longer. On the other side of the driven element is one of more slightly shorter elements, directors. Because of the specific distance and specific longer length, the reflector interacts with the RF from the driven element and bounces it back.
The director elements are again a specific distance and length shorter than the driven. The RF interacts with them in more of an attractive manner, drawing more of the radiated energy in that direction.
The opposite is true of receiving with it, making it more sensitive in the direction of the director elements.
I doubt the precision of this slip on "yagi" thing is good enough to work well at all.
@BenBenson The parabolic works as a reflector.
Think of a wire antenna like a light bulb. It throws light out all around it. In a flashlight, there's a parabolic lens placed on one side of the bulb. All the light that comes out that side of the bulb gets reflected in the other direction, leading to much more light in that direction.
That's how it works with the RF coming off the antenna.
As for the disparity in distance testing, yes, environment. These drones use wifi at 2.5 GHz. (also at 5 Ghz, which has an harmonic relationship being a multiple of 2.5) At that frequency, a water molecule is at a resonant size and absorbs the RF. This is why microwave ovens operate in the same frequency range.
That also means that higher humidity in the air will reduce your range as more of the RF is absorbed by the water in the air.
I got a new potensic atom SE… how can I boost my range?????
Impressive test, was just looking into the Yagi antenna intro & that's a nice example right there!
I have the dish, a 5 rod Yagi (5.8 Ghz) and a 8 rod Yagi with a rear side extension and these seem to be the best so far. It also really depends on what channel I pick (165 seems to be the best). I need to do more testing. This is all in a heavy urban area.
Good morning Sir. Great and exciting video Nick. I also have the Dji Mavic Mini and i love it. This little machine is a BEAST. Keep those great videos coming. Nicely done and good JOB. Thanks to you and others i also ordered a set of these yagi booster and i cannot wait to get them in the mail. I have been hearing good things about it and i cannot wait to test them out.
You just got yourself a Big fan and a Big supporter here Sir. Let’s help and support one another. God bless and stay safe. Have a great day Captain. Thanks for all you do and please keep flying.
Thanks so much for the support!! I’m so glad you enjoyed the video!!!
Awesome comparison dude!
Thanks!! Check out the video where I tested combining them if you get a chance!
Thanks for the review! Just ordered some Yagi's!
No problem! Check out the video I made when I combined them!
@@nickdaly5104 will do!
3year ago. But I have the yagi with The rubber mounts no scratches. An the mirrored one's also fimi mini x 8 mini pro. Gonna give em a try. Thanks for the videos. Keep on flying my friend
Did you try the extenders out with your fimi mini and if so how did they perform?
Get your own!
Double Up (FCC 5.8GHz) ! amzn.to/3mTO6sg
Yagis (FCC 5.8ghz): amzn.to/3zG61KW
Parabolic Reflectors: amzn.to/3zL6N9v
Great test
Excellent review
I ASK THE QUESTIONS EARLIER ABOUT PUTTING THEM BOTH TOGETHER, JUST SAW YOU OTHER VIDEO WITH BOTH,,GOOD ON MATE
tq so much☺️👍
Just take a key file and make the holes for inserting the MM antennas a bit wider for more easy fit. I have made my Yagis by myself, based on a Thingiverse design for 3D printing. Both the 2.4 and 5.8ghz versions will fit quite easy without scratching.
Gerd Staudenmaier thanks! That’s a great tip!
Good video!
Thanks!!!
The reason you were able to keep the drone going despite having no video feed is due to the 2 different frequencies used for communication. The drone is communicating on 2.4-2.5GHz which is has a longer transmission range than the 5.8GHz the video is transmitting on, thus the video will cut out before the aircraft truly loses communication. In fact, the drone is programmed so that as soon as the video losses communication the RTH engages despite the fact that communication isnt lost with the drone, this is why you were able to fly on after ignoring the RTH.
Another thing to note is that you will actually get more range flying the Mavic series backwards because the antennas are mounted on the front landing gears which communicate best when directly facing the RC.
Over all I love this video, very informative.
You summed it up nicely! Thank you 😊
thanks for the video..i have bot for the Spark..juse them both at the same time,.
Both work. Even together.
Parabolic is best for the 2.4ghz range. Yagi Uda for the 5.8ghz range.
They're not really meant to "boost range", but rather focus the signal to provide more stable connection.
So yes, the absolute best is to use BOTH at once, the parabolic will redirect ALL frequencies to the front, while the yagi uda's will tune the 5.8ghz even narrower.
Nice content.
thank you
Glad you liked it!
Dude! the best review of range extenders I have watched, AND HAVE WATCHED LOTS, Awesome !! btw, is it just my Eyes (old)! or is the Video "quality" better all the way with the Parabolics ??
Thanks! I think you’re right about the quality being better with the parabolics!
@@nickdaly5104 thank god ! it's not just me then ?? watching your vid is so easy if you stare at the center of the three vids , eyes wide open , and the top right vid is the best !! Greenist most Luciuos vid !!
@@nickdaly5104 well hey! you have got to take Vid Quality l over Range , all day any Day !!
I was waiting for one of them to lag and my computer lagged first..
Nice
very good Side by side comparo.
Thanks! I appreciate it!
thank you been looking because i can’t go past about not even half way by my house
Have you considered testing parayagi?
Putting both the parabolic and Yagi on the controller together.
I haven’t tried that yet but a lot of people asked so I might need to make a video on that! I’ve heard it helps though
If you haven’t seen already, I tested it! Parayagi is a clear improvement. The video is up
Good video
I couldn't decide if I wanted to get the mirrors or the Yagi's I figure I can make a mirror myself the Yaghi's however not so much as looks like the Yagi's work better so I guess I'm going to go with those I think I might want to do both the same time though maybe a parabolic mirror behind the Yagi's
I now use the combination of the two. I just posted a video comparing them to the yagis by themself
Before you put on your Yagi extensions, wipe your plastic controller antennas down with armor oil protectant. This makes it easier for them to be removed.
Best ever comparison..idol neeww friend
We hope that these types of antennas are calibrated with the TX frequencies of the radio control, and therefore the manufacturer of the antennas has used suitable equipment to build them and relatively put them in "tune" with the TX frequency of the radio control. Otherwise, if not, the transmitter loses efficiency over time or in the worst case you can "fry" the transmitter amps for high SWR. 73 'by iu8cew
They run on wifi not radio waves
@@nickdaly5104 why, the wifi does not generate a radio wave with a certain RF power? lol the remote control always has a transmitter inside with a small amplifier, the principle of radio frequency is always the same.
Good comparison, so I should go for yagis
Liked and subscribed 👍 good luck mate
Thanks! I really appreciate it!
I hear u can use both at once to get great re reception
Parabolic mirrors for city use and Yagi 2.4ghz antennas for long range in the country or mountains!
I've just bought some parabolic dish and they've not made a difference in my urban area , not tried in the countryside yet .
Would yagis be better ?
Are the mirrors better on 2.4 or 5.8
Can you attach thoes Yagi antennas on the antennass on the goggle 2? Do they improve the range for the goggle to transmit video
Wondering if you could put the antennas on the mini se front legs and then put the reflectors on the controller 🤔 and then see what really happens...😃
Hi nick,,I just purchase the yagi,,but sadly the seller send me different piece, one is for 2,4Ghz and one 5.8Ghz, what if I put them on the same remote,,is it going to be fatal? or ?
From what I learned so far is the Parabolic is better with 5.8 and in Urban and Yagi is better for 2.4 in rural.
I agree!
👍👍👍👍👍👍👍
USE LAS DOS CON PHANTOM,SPARK Y MINI ME QUEDO CON LAS YAGUI PARA 5.8 EN CIUDAD...
i hear that using both at same time is best?
its best to use both together for best result parabolic Reflectors and the yagi antennas gives best result together
b4 watching both together the Yagi u have to point straight at the drone the others have a wider range Yagi is a narrow range, use both if any
Have you tried testing with yagi +parabolic at the same time?
Hello, what happens if the two or three antennas are combine? Good Videos.. Gretting from Costa Rica.
Good question! I just made a video doing that test
Typing this before I watch the video, I purchased the yogi antennas today. crossing my fingers..
Are they good? Because I am also thinking about getting them.
I got both
Yagi-Udo antennas. Fixed that for you.
If you're going to correct someone you should at least get it right.
@@chrisneate6995 oops. Yagi-Uda is the correct spelling. My bad. Thanks for pointing out I was wrong and somehow not following your own advice. You also did not 'get it right'. You just put a big ol' 'X' beside my answer and added nothing productive. So while technically correct in your statement, it's still not helpful.
What drone are you using for this test
Have a question I bought the mini and when I am in a valley that is 1/4 to half a mile across and 1000 feet high on both sides I get allot of signal problems. I have tried both, the mirrors and the Yagi and still have problems with signal. Does any one know why. I had good satellite and WiFi signal at start then it goes bad after about 1000 feet.
Is there anything between your antennas and the drone? Trees, buildings, ect? Those will limit the range a lot. Some directions I can only make it about 1000 ft because of buildings. If you make a video showing what’s going on I might be able to figure it out. Let me know
Close to 2 miles on a Mini 1 in the city is impressive
You might have gone farther is you use the 2.4 yagis. I would lube the antennas with vaseline. Just a very thin covering.
You are right. He used the 5.8 GHz yagies on 2.4 ghz
Why lube the antenna with vaseline?
Why not both ?
Do they work with the CE model?
You doing better with a mini 1 and controller than i get with my mini 2... i lose vid at 3200meters. Im in the suburbls with 10k of wifi routers
you should have also put the 4th screen with yagi+parabolic combined :D
haa found it, thank you sir! new fan here :D
How far can you get with parabolic mirrors AND the antennas used together?
he put up a video
I have a dji mavic mini CE version. But I managed to switch it to FCC now. So which Range extenders are better for me? 2.4G or 5.8G?
You need the 2.4 version for a CE drone
I've seen conflicting results, I'm in Europe and I know I've seen people get like 3.5km with parabolic extenders but get worse with yagi so idk what to get im getting my mavic mini in a few days.
The area that you fly and the physical obstacles make a big difference. I choose this path because I have a clear signal path with no physical barriers. Leaves on trees hurt too. I flew from somebody's house in the woods and I couldnt get more than 1,000 ft because of the trees
Nice video and comparison!! Do you have the FCC or CE version?
Thanks! This is the FCC version!
@@nickdaly5104 Will, you be interested to try this modified (added reflector) Yagi? We live in a rural area and want to know how it performs in urban areas. Here is the picture www.miniformer.com/ebay/MA-09-05/experimental_yagi.jpg
Nick Daly thanks video. is yagi works with 2.4 ghz ?
Yalniz this is the 5.8ghz Yagi. The 2.4 is the longer rods
Sure I’d be interested. How do they work in the rural environment?
You're Standing on the Roof ..... with Clear Line of Sight ! ..... Are you holding your Radio or is it Stationary ? ......... How far can you go Standing on the Ground with houses and trees in the way ? ...... I like the performance of the Yagis and their small size ... But how Narrow is the Beam ? ..... Can you use the 2.4 Ghz ones .... are the the same ? Cheers !
I'm holding it. If I was standing on the ground the range would depend on the physical barriers. This test is more about how the Mavic Mini does vs wifi interference. Not sure all the physics behind the beam width but when you get out pretty far you have to make sure your pointed right at the drone. The 2.4Ghz are different. I'm on the FCC version.
What do you mean at the end of this video when you say less damage to the controller antennas?
Scratches on the plastic.
With the yagi do u have to point the controller in the exact direction of the drone or the general direction?
Supposedly so.
Did you try them?
I'm in the process of ordering a pair that are fully silicone so they don't damage plastic antenna and are universal...
TRY TO USE YAGI ANTENNA FOR TELEVISION (OLD TV), TO YOUR REMOTE DJI DRONE, BELIEVED ITS WORK..I HAVE TRIED IT, I REACHED AROUND 22000FT.., ITS CRAZY..
It sound a good idea but TV frequency is 6-700Mhz where we are using 2.4Ghz. All the aerials work on the same principle.
Do you have the link for yagi extander range on amazone please ?
Link is pinned in the comments!
Both together..
I agree with Jase K that you would have done better with 2.4Ghz yagi where I believe you were using 5.8 version.
It a strange phenomenon that the range in the same place changes from day to day depending on humidity and environmental factors.
You’re definitely right how much the environment can change things. I couldn’t get over 7000 ft in the same direction today with the yagis
Did you know you can use BOTH antenna boosters at the same time?
I do! I actually made a 2nd video comparing the combo vs the yagi!
you can use both of them together
did you have used the same frequency in all three tests?
and what happens if you do not hold the controller with the directed antennas exactly in the direction of the drone?
I left it on auto. I actually had to do the combo 3 times because my screen recording didn’t save but I got the same result
If you don’t point straight at the drone it loses signal. It’s not a big deal until you get out pretty far though. As long as your drone is set to RTH if it loses signal it will come back
I had a bird attack mine at 400’ up and 500’ out. That would be bad out 10,000 feet. Eagle had a bad day too. Stupid bird. Broke my prop and the arm when it fell that far. Long day looking for it. Turned off on impact so no beeping to help.
My experience with a combo parabolic mirror/yagi was no real difference. Lost signal at same place both flights.
Is this ce or fcc mode?
Have you tried using both at the same time?
Trevor Ker-Lewis haven’t tried yet but I plan to!
Can you use both Yagi with Parabolic mirror together? Will this be better?
Yup! Check my other video!
@@nickdaly5104 Do you have another Amazon link for the 2.4ghz that you have tested? Which channel is better?
The Copper element Yagi is a bit more efficient than the aluminum.
copper costs significantly more tho and imo yagi + mirror would be better than just copper for cheaper and its less focused on one direction
Where did you purchase the yagi antennas from ?
rocky A amazon!
@@nickdaly5104 do you have a link ? So many companies are copying it.
Aliexpress for 9$
I use the Yagi 5.8Ghz and the Yagi 2.4Ghz. Depending where i am flying. The 2.4 works better where there are lots of buildings etc. And the 5.8 works better in rural areas. Just a case of switching over and changing controller settings from 2.5 to 5.8 whenever needed.
You got that backwards
2.4GHz signals can penetrate obstacles like trees and walls more effectively, yes, but 2.4GHz is a commonly used frequency band, it is more susceptible to interference from other devices such as Wi-Fi routers, Bluetooth devices
This video made me a nervous wreck. I've yet to take my mini out that far.
Haha! Yeah there’s definitely been some nervous flights for me. As long as you watch your battery percentage, aren’t flying in high winds, and have the home point set with double digit GPS signals you’ll be totally fine
Damn near two miles away with them yagis
lol, they make no difference
@@MrMusic55123 bullshit i have the yagis and I get an extra 500 to 1000 feet plus the signal doesn't drop as often..
2:40 lost compass?
It seems to happen when the signal get's lower. I think the mirrors impact it too. I havent noticed any issues from the GPS because of this though.
Good video but you got to increase you altitude as you go out you never went over 400
These are the FCC version!
Im glad it is and of course you never lose VLOS because why would you not have spotters at that distance right? 😉
Nope! That’s the best part about the harbor giving me such a clear lane. Spotters are right there too
@@nickdaly5104 I could never get 3k ft with mini2 (no booster). And it's not even in the city, just normal residential area
Do you have a clear signal path from you to the drone or are there trees and buildings in the way?
@@nickdaly5104 yes lotsa trees. never thought of that because drone is way over them at 300-350 feet
Have you tried the 2.4 yagi`s yet mate that would be interesting against the 5.8 ones
Haven’t tried those yet. It would be interesting to see if it makes a difference since I have the fcc version and I’m pretty sure my transmission switched to 2.4ghz at some point during this flight
@@nickdaly5104 FCC only have 5.8Ghz, do not bother with yagi for 2.4Ghz
@@Puksion I never knew that 👍
What if you use both?
I just made a video using both!
What damage do you speak of at the end? It just plastic on plastic. Seems to just slip on.
mine was just from a crappy 3D print scraping. yours might be different. I've since gotten a silicone yagi and have no issues.
why not both?
its ok u uploaded the video
WiFi signal probably was still susceptible to interference in the city regardless
When are you guys going to adopt the metric system like the rest of the world?
Haha come on man it’s very simple and logical! 1 mile equals a nice round mathematically convenient 5280 ft.
@@nickdaly5104 I mean you guys adopted the 9mm like a charm ;)
do use FCC or CE?
FCC!
Who watch now 2023 ‘ the signal now of mavic mini 1 with two booster got 300m distance its interferer weak signal
Hi its ce or fcc?
Francisco Trindade FCC!
it can go a lot better than that.. the parabolic is far too small basically a have..and the yagi cant align properly with the driving antenna. you can follow up on the net about these things... i make and use grid and yagi antennas.. lte.. wifi .. ham
Careful there’s a guy calling in to the faa bout everybody flying outta sight and uploading the videos lol
Turn the 5.8 off and just run the 2.8 and u will not load the video feed
Y'all need Ocusync 2.0....lol.
Oh yeah! Check out the video I did comparing the Mavic mini vs mini 2. Crazy difference
@@nickdaly5104 Yes, the difference is vast, no comparison.. Ocusync 2.0 on the Mini 2 is good for 10kms using an extender Lipo...🤔🤔😀🇬🇧🇬🇧🇬🇧

Seems to take a while so I will get back to you later when my account password hopefully is recovered.
@Willie London it worked and I actually got access to my account again. Im so happy:D
Thanks so much, you saved my account !
Oh come on dude. Why did you not try the parabolic mirror reflector with the Yaqi antennas? With the advantages they both provide for. Try using them together. Then maybe you won't lose your video feed at 10,000 feet.
Notice the video returned when you rotated the drone. The parabolic mirror reflector might help to better reflect and focus that video signal into the Yaqi antenna array. It might increase the reception by a DB or so worth of signal strength.
And so be careful with those flimsy little antennas. That DJI is now phasing out altogether. Then what do you do? As they build the antenna into the spring-loaded smart phone monitor mount. Who's going to make what, to improve, those?
As an engineer here is what I would like to see on my drone remote controls. An, antenna socket. So that one could plug in, higher gain and/or higher in altitude, staff mounted, antenna system. One would wear as a harness/belt. And because most of the signal strength is based upon antenna height. Then the higher you can get. The better. And also the antenna.. Just don't fall off. Because you shouldn't be standing on a chair. You should be on the ground. With your antenna in the air.. And so you need to be able to wear a nonconductive antenna mast. And heavy rubber boots. In case you are hit by lightning. But your drone should be able to fly further that way.
And so. As an engineer with an FCC 1st Class Radiotelephone License. I am authorized. To install antenna socket. Onto my remote controls. And don't think I won't. You'll just be able to plug-in an external antenna if one desires. It will disconnect the onboard antenna. And you don't want to be standing underneath any electrical wires. It could be bad for your health. And your remote control. So don't do that.
Now I've got this really groovy, telescoping plastic mast. It's only about 7 or 8 feet long. It goes out to like 40 feet long. It's awesome. Perfect place to put an antenna and a pair of, forward phasing and rear facing wide-angle cameras. So you can always see everything coming and going. Add a little flag. And everyone will know where you are. Add some colorful blinking LED's to the flag. Just to let them know how flashy you really are. And you will be the talk of your town. Nobody will want you walking indoors. Because you won't fit. Don't forget that. You've got a monkey on your back. You have to walk around with. And it goes 40 feet high. If you aren't already.
I'm so glad we had this heart to Fart talk.

PS
Doing this for network television for 20 years will do this to you. I can't help myself. Competition is stiff amongst the major television networks. And they only wanted the very best engineers like myself. To come up with great ideas.
Really I just want to mount a MAVIC Mini-Air-Pro that has a broken arm. Or 2.. That still has a working camera and gimbal. To put on top of my 40 foot telescopic light weight plastic mast. Instead of some stupid Go Pro with electronic image stabilization. No! I want a 3 axis gyroscopic stabilized gimbal mount. I'm sorry. That's just me. Screw electronic image stabilization. I want gyroscopes stabilizing it. Gravity thinks better than integrated circuit chips. Gravity knows what to do all the time. And gravity likes spinning things. So do the planets and the stars. There's something to this spinning stuff. I'm pretty certain of. I mean what would gravity be if we didn't have any big balls? You have to have big balls to have gravity. Those are called planets and moons, asteroids and comets. They all offer something for you to stand on. Jupiter, Saturn, Uranus and Neptune also. But would crush you and burn you to a crisp before you got there. To find out what you can stand upon. How hot or cold is metallic hydrogen? We don't want to find out. Not personally. It's great that it exists. I don't know what we would do without it? It's nothing we want to be directly involved with. And certainly not smoking a cigarette around. Near any oxygen. Though, I don't think a cigarette will work without any oxygen? So don't even try that around any metallic hydrogen or any kind of hydrogen for that matter. I'm sure the guy cleaning up the hallways of the Graf zeppelin simply dropped his cigarette. Oh the humanity. What a bunch of dumb asses. (But you didn't hear him say that)
You'll be happy to hear I made a 2nd video a little after this one doing just that! ruclips.net/video/R1PhlA7nLY8/видео.html
You’d better put on the americans-only disclaimer. Too bad I don’t speak yards and feets
They're NOT parabolic at all.They are spherical crap I'm afraid.
I hate to be that guy but you are far out of vlos, and not only that but your out of vlos with no video feed just continuing forward, kinda risky.
Nice
