- For about $4 in parts you can build a helical antenna that provides a huge amount of gain and significantly increases the range of any 5.8GHz FPV system in a drone or RC plane. This DIY video shows you how to do it and I'll be posting more tests of the 5-turn and 3-turn versions shortly.
If you want to see the real-world tests just jump to 00:26:00 in the video. - Věda a technologie

I've seen your videos when I was a kid and now I'm flying because of you!
Such a nice comment and compliment to make and he doesnt even like it or say sonething back :-(
@@OneOfTheRobs maybe there is reasons a creator dosnt read comments
@@OneOfTheRobs That’s Bruce for you.
@@wattage2007 who is Bruce for me?
When using epoxy to secure an otherwise (plastic) incompatable material, I find it useful to drill a series of small holes around the circumference, quite close to the base. These are loaded with epoxy and when the epoxy from the base makes contact, all become a "keyed" construction.
recently, I really have gotten more into Antennas in general and I am fascinated by the creativity that adheres to formulas and mathematical rules that antennas have to go by. I have much to learn.
I made my first one and I am blown away with the results! Thank you so much!
Greetings from Italy Bruce, with your help I finally got around to building my own helical antenna and it works quite well! I'll be doing some long range testing over the weekend. Thank you so much for this great video and everything you do for the RC community! Ciao!
Thanks Bruce for the motivation and inspiration to build a 5-turn helical antenna. I built one, using a 3D printed former, over the weekend and my testing showed that it far exceeded the performance of a commercial 7-turn helical that I already owned. The VSWR ended up being 1.6:1, which is not great for Tx but adequate for an Rx antenna.
Bruce good to see you getting back into the tech side of the hobby and showing us how to DIY stuff! Thank you good sir from Southern California
16:30... bruce im shocked but Trev would be proud
Absolutely fab Sir Bruce. Have missed the DIY vids. Always best to make them yourself. So much more rewarding.
I’m learning to make a Helical at 2:26am, Woo Hoo 👍🏻
Steve B lmao im doing this at 1 am and i have end of semester testing in about 7h
2:21 am for me 😉

Great video, Bruce!!! The fact that you didn't over engineer the antenna or sweat blood over exact measurements and still have it work quite well, should encourage those of us that aren't amazing at crafting objects to give it a go anyways....and enjoy the results! Cheers....Jealous Josh in chilly Saskatchewan..enjoy summer my friend!
Great video, I'm definitely going to try this out. Thanks for putting this video together and I would like to see more DIY stuff.
Your DIY videos are by far my favorite of what you do.
Started watching your vids from the diy fpv backpack days. So much has changed since... except the quality of your content. Keep those great vids coming Bruce!!
thanks for keeping the DIY dream alive in this world of "just buy one"..
sometimes i want a thingy RIGHT NOW, shipping takes time, so having the skills to actually make your equipment is awesome :)
remind me of when i was experimenting with long range 2.4ghz wifi (back in the early days, about 15yrs ago), hand made biquads on scrap copper sheet, baby-food tin can-tennas and house guttering waveguides.. all good homebrew stuff that worked, well before commercially available gear
cheers from across the ditch!
Well said
These are my favorite videos of yours. Keep them going!
Another very useful guide. Thanks!
Oh, and I want more DIY. ☺
I'm going to 3d print some parts and make a few of these. Winter is a great time to build while waiting for good flying weather. Thanks for the info!
bruce, thank you for going back to making good videos again. RC planes, electronics, good and bad buys, and good overall knowledge of the hobby. I subscribed again and enjoy your content.
Awesome video Bruce !
I hope you enjoyed it as much as I did :)
Best regards and health from Holland
Nice Bruce!
I have been using Farvew's open source files to build my helical antennas for a few years now and have been loving them!
I am quite amazed and inspired. Thank you Bruce!
Great instructional video Bruce. It's awesome to see such good results by making something that's accesible for everyone to have a go at.
So informative please please can we have more. Just love watching your videos.
it's VERY valuable for older people that we can relate to ..to share what happens to us physically as we get older...mental/spiritual/physical/strategic preparations etc!
Nice job Bruce you truly are an awesome guy I appreciate all you do for our community
Nice, that will be one of my next projects. I already have a triple diversity receiver, so this would be a good solution for FPV flying planes.
Thank you Bruce I thoroughly enjoyed that video, i love tinkering I may have a go at one of them myself. im just started in to FPV bought the stuff over a year ago it's just been sat in the drawer 😏 thank you again big salute from South Wales UK 🏴
thats an awesome build video. i understand how those antennas work better now. thank you!
Excellent, more like this, please. I need some omni love at 868.2
Lol...another R9M customer, mines awful too if that helps, and Im using a True-Mox on mine.
@@EnglishTurbines Ah almost, I need it for a glider tracker, it's all LoRA though. I think coax and mounting are super important at relatively low powers involved.
I would like to build some of these, Sure wish you would post links to a parts list. I could be sure I order the correct parts. Love the DIY videos.
Great job Bruce
I LOVE THIS SO MUCH!! THANKS BRUCE! Gathering materials now! 👍👍
excellent video Bruce! love the building and figuring things out side of the hobby as much as i love to fly. Going to give this one a shot once Crimbo is over! Happy Christmas to eveyone :)
Thanks for the video, Bruce. Very helpful especially for the simplicity. Just to double click on this a bit, if possible could you share the calculations you did for the distance between the spirals, etc? Thanks again
Never hurts to experiment , good idea.
Man your a legend to this hobby Bruce. Love your work mate. Merry Christmas to you and your better half :)
I LOVE this video! This explains a lot why the FPV camera I tried in our clubs rc trucks gave us horrible video!
Excellent Demonstration, ..... Thank You
A really good instructional video Bruce.
Nice to see the " Velocity factor " being used 👍
Totally cool, I am going to build a 1686 radisonde receive antenna. Keep it up you are providing data to a radio junkie
Great! I recognize an OM when I see one! Fantastic job, both the build and the test! 73 de LA6UOA!
Thanks! Love to see more diy.
Great video . Thanks mate .Cheers from Australia
Very nice job on the project and great demo of a helical. Look forward to seeing the effects of more experimentation with length, etc. Making something by hand is so gratifying isn't it? :) ☮️ Wheelchair John in Idaho 😎
Loved it, will build my own soon :)
Hi bruce ,I am three years late with this video but I like it and it is not that bad at all bruce I think it looks pretty good and it works ,thank you Sir .
Awesome work Bruce.......Merry Christmas
Great video I've just made some and they work a treat thanks for the great content
Very interesting, thanks Bruce!
This video just made me subscribe. You have some great knowledge. I m a lifetime student. I love learning. Thanks for your quality content. Keep it up 👍.
Very cool and educational video..thanks for sharing 😊
A good heat gun has been on my bucket list for years and years. Guess I should do something about it . Altering dementions this antenna would be quite handy for WiFi as well.
Great video Bruce! As allways. ...
Nice sidecutters by The way :)
:-)
Great video Bruce
Good one Bruce. Thanks.
As always , Awaresome Bruce . Gave me an idear what to do on my christmas leave :)
Great video! Who knew it was so easy? Thanks for the information. Please do note vids like this.
Thank you Bruce your a fpv treasure!
Perfect , im gunna build myself a big patch antenna and a helical !
Bruce ...... inspirational, keep it up mate :-)
Thanks bruce for the Info.
I will now trie to make my own.
BTW I love the fact that Nz uses the metric system. I cant underastand this 3/5 17/6 stuff from Imperial 🤣
that's what i use Frsky receiver packaging for too.
Thank u for this video yes I'm planing to make it thank again for teaching us.
You know, i really respect you man. Thanks for the tons of info, i never knew its possible to use 2 helical for a diversity goggles, you just gave me an idea!💡now i have a project to attend to.
Thanks, Bruce!
I love your diy videos Bruce. It hurts me to see the difficulties you get with shaking hands 😢
I wish i was your neighbor. You could learn me, and i could help you. You are a great guy Bruce !!
It still hurts me that i wrote a couple negative comments (backpack / diversity Rx) some years back, Im sorry..hope you can forgive me.
Keep you hobby / work and videos going.
Marry Christmas / Happy holliday to you Bruce and your family 🎅🏻🎁 From 🇳🇴
This is freaking great.
Thanx man.
Marc :)
Thank you Bruce, might try this for a WIFI link too.
Thanks Bruce!!!
Thanks! I'm making one 👍
Yes, yes, yes, more DIY please 👍👍👍
For sure Bruce those little heat guns though cheap are nice to have, It sure does make your project much more professional when you have the right tools for the job, My Heat gun is a HAKO much more expensive than the standard unit off ebay but i own one of the cheap ones as well that i use in the garage if it gets stuffed oh well ill buy a new one.
will try this. thank you
sorry your dealing with Parkinson's, my best friends dad had it however he still lived a long life. ah new Zealand, hope to visit there some day, looks like paradise on earth. i do mostly dlg and gliders so i think id have a lot of fun there with the diversity of terrain and weather conditions although here in the state of Washington there's always fun places to slope or find some thermal activity..
Thanks again for an educational video
cheers Bruce, very informative :)
21:20 all good calculating the exact multiple of a half wave for the coax, only to forget about the transmission line formed by the SMA male, SMA female on the gear and feeder or microstrip internal to the goggles lol. When it comes down to it without putting all these on a VNA it's all best guess for the builder :-) Amusing to watch though, keep it up.
So awesome. Your videos are great! :)
Can't wait to give this a go.
Thanks for the tutorial.
MUITO BACANA SEU TESTE COM ESTA ANTENA! BREVE VOU FAZER ALGUMAS COM VÁRIOS TAMANHOS E FAZER UNS TESTES! OBRIGADO PELO SEU TEMPO E SUAS DICAS! ABRAÇO!
Great video learned a lot
Great stuff keep up the good work
Great video.
Great work
Thank you, Bruce for another very informative video.
From FPV drones now im playing with antenna's - thanks for this! I was thinking of applying clear coating on the back plate that is bare copper since it can and will probably get oxidized.. what you think?
I always asked myself, if I could build multiple of these and connect them together to get a better signal, or to point them in sightly different angle to have a wider area to fly.
Fantastic!
You make electronics fun!!!
Thanks for your help
If you really want a nice straight piece of wire put it into a drill chuck and grab the other end with pliers. Spin then wire while giving tension straight out with the pliers. after a few rotations the wire should be super straight with no visible kinks or bends! works a charm!
Good video 💯❤️
Well done, thank you. Is there any chance you'll build a high gain helical for passive digital television reception, 1-2 meters long?
Is there any chance you'll add a few turns to it and measure the beam angle to get even more distance?
What would happen if you used multiple strands instead of the single strand ?
Where is the web site / pdf?
This was a great video. I have made one for 868 MHz but need an antenna for the plane. All the designs I have seen for clover leaf and skew planar antennas in 868 are really big. Are there any smaller circularly polarized antennas suitable for aircraft in the 868 frequency?
Sure more diy. I did a 5 turn scratch built one a while back and it works well. If you wrap the wire around something slightly smaller it will be tight on the tube.
Bruce, I'm 23 and have no conditions and I'll be damned if I can get those screws in the right angle connectors. Took me 15 minutes one day to get one of those POS on.
Hey Bruce that’s brilliant. Yours tested to a horizontal range of approx 50-60 degrees, but what would the vertical angle be approximately? Could you fly almost overhead with it? Many thanks.
Hi Bruce Thank you very much for showing that a lot of the gear we use in FPV flying can be made by ourselves and be very effective. If the the tube is pushed through the reflective plate would this produce a lost in the antenna. Also I will be passing through your part of NZ next February, I will have to drop in.
Yes, you would likely lose some performance if you passed the tube right through the reflector.
marley spouting glue is the best ,and non conductive ,i use it on all my drone plugs and wires going into plugs ,it keeps moisture out and is super strong with a wee bit of flex ,and its good to glue down broken off plugs u solder back to a board
