- 2.4GHz Parabolic Blade Antenna
In this video I show you how to construct a directional antenna that still retains omnidirectional properties. This antenna works the same way a down light works, focusing light down from a ceiling this little antenna does the same thing but with RF.
The design is based on the blade antenna I made but this time it has a 51mm diameter parabolic reflector.

This is the most beautiful of anything I have seen on this earth Amen.
This is a brilliant build and how right you are about RF being radiated out and up when we are underneath our quads.
this really helped me with a project I am working on.
Andrew after doing a little bit of investigating about the hertzian dipole now I understand about 25mm thanks man you rock
No problem Lorin
I have been using a can opener that slits the folded portion attaching the lid away cleanly, works even better than the regular can opener that cuts into the top of the lid. It would make short work of removing the portion that you want.
A lot of needy people. Andrew shows you how to make all his antennas yet people often ask to buy from him. I think that if wanted to sell his antennas he would have advertised this bit. Those wanting to test his antenna and want Andrew to send them one for testing. Stop. Make it yourself, then test it.
ya do realize that Yes, he does sell them, he has a store
Man i would buy 1 of these for sure.
Ok Andrew my first attempt at making an antenna and it's this one, gotta work on my soldering skills but not bad and also fairly easy to make, right now I'm using RG 58 coax but I do have better ordered just waiting for it to come. I plan on making quite a few other ones of different styles, I'll keep you up to date with my progress.
Thanks for your common sense videos

Happy to test an antenna, looking forward to the 5.8GHz model.
James Lamb No problem James Happy to send you one. andrewmcneil@hotmail.co.uk
HI Andrew, great video thanks. I appreciate you sharing your knowledge in the straight forward and sharp but relaxed manner that you do.
This is a perfect design for fixed wing i would think.
I'll be happy to test the antenna out for you
Thanks Oscar Bishton
I really reall wish you would once show us dimentions for LTE, 3G and 4G... this is great work!
Depends on the cellular network. You’d have to look it up for your carrier.
Looks cool. Would love to test one and do some rssi comparisons. Least we can do after all the great work you shared here.
I seem to remember indoor tv aerials that looked a lot like this
Thank you for your excellent videos. I currently live in a very rural area and barely have a 4G LTE signal. In order to improve my signal strength I've been exploring antenna options for a point to point setup to the cellular tower. I have an old satellite TV parabolic dish and will be using it. I though I was going to use a traditional biquad feed head until I watched this video, and your round lobe biquad video. Both appear to show outstanding gains.
Which one of these antenna's would you recommend as a feed head in a parabolic dish antenna for point to point wireless internet reception/transmission?
This parabolic blade, your round lobe biquad, or a traditional biquad?
Thanks.
Thanks for a great Video, the problem of the antenna it is not sirkuler polerisation, it gives problems with multipathing FPV. interesting do it with a cloverleaf antenna...looking forward to the 5.8GHz
Your antennas looks very professional, it's amazing how you put all the materials togheter, i live in the country so i don't even know where to take the stuff i need all i can think about is to buy a cheap chinese antenna from a shop and use the connector and the wire to build one like yours and take apart an old transformator for the copper wire; what you think about?
one of my most fav video by Andrew :)
Hi Andrew, another great video! Thank you for your time and effort. How does the can diameter effect reception? does it just need to be wider than antenna, or are other factors at work?
Ers un genio haciendo antenas gracias por tus videos
superb stuff & thanks for the great help!
Wow, New to fpv, This looks like something I'd love to try out.
Hi Andrew, Can this design be used on 5.8 freq as a directional recieving antenna?...and if so, what kind of transmitting antenna would be best?...Could a linear or Rubber Duck be used on the transmitter end?
Great video, thanks Andrew!
Alexey Novozhilov My pleasure Alexey, thanks for the feedback
Andrew, why in some videos do you use 31.5 mm and in this one for instance 25mm for 1/4 wavelength at 2.4 Ghz.
I have made several of your antennas and they work very well, so much I have started playing with my own small modifications.. Thank you
Gary
awesome build thanks friend
George Alexandrou My pleasure George, thanks for the feedback
Great video !! Great stuff too ! Continue pls !
Another good project,yet again nice work.
I have a new one for you if you fancy it .How about an external GPS antenna for the nexus / hudl might stretch the little grey cells little.
Hello Andrew I love to watch a craftsman that's good at his craft ,I have watched many of your videos in the last few years and i would like to get your input into building a lightweight compact 5.8 ghz L/H polorised antenna for use on fat-shark goggles and to get as much punch into the signal to combat going through the tree's .I use two fatshark LH cloverleafs at present but still get significant breakup when going around the trees.have you any recommendations as i would value your input sir.
Cheers
Hi Andrew
As you have demonstrated many wireless antennas, I was just wondering if you had an absolute favorite wireless antenna that simply performed better than the others. If you had to choose one out of them all.
Walt
Sweet. You take shit apart and whip it back together better than it was. YOu make your own antennas...do all kinds of sweet things. Where did you learn all this ?
Great informative and creative video :)
nice video!!! verry intresting!!...just a thought here for fpv use...if i do a parabolic "left hand" circular polarized antenna and mount it upside down, wouldn't the receiving antenna need to be right hand polarized assuming its pointing straight up in order for the signal to rotate in the same direction?....other thought I had was if you could just hotglue a parabol on top (not making contact )of a Cp antenna like a hat or umbrella and have the cp antenna pointing upwards...like a mushroom...
love your videos and all the best to you!
i forgot to empty the can of air spray and got a chunk of metal stuck in my face. I'm not blaming you andrew but if you would just sell me an antenna i wouldn't have to risk my life making one sir. lol :P
Andrew, any chance of creating a video for a Parabolic Cloverleaf for 5 Ghz ??
Some additional information regarding the aerosol can, two sizes available.
The linear diameter of the base is 51mm. This gives a parabola of 46.11 mm, depth at 9.04 mm. This results in a focal point at 14.69 mm.
Also found a larger can, linear diameter= 65.60 mm. This gives a parabola of 63 mm, depth at 8.5 mm. Focal point at 31.03 mm
Thanks for this video andrew. how would it be possible to get one of these cos i need a wifi network booster for my laptop, and if theres an updated version, that would be great.
i'm wondering if is possible andrew mcneil
How i can do the same with satellite dish by help of electricity ?
Thanks
Thank you Andrew.
This video was 4 years ago. Do you have any links to people fitting this to DJI Mavic mini drones and doing range tests?
Hi Andrew absolutely fascinated by the clips i have seen, very easy to follow even for a pure novice,
Question i hope you can help me with this i have a huwie 3g router for my broadband connection there are no obvious ways in which to boost what is a very poor area so i was wondering if i made a blade antenna as per yours is there a way like a base plate i could sit the router on which would increase my signal or is this only in my head hope you can help.
We cannot get broadband by any other means
many thanks
When you solder parabolic reflector to metal tube . Doesn’t it change balun characteristics ??
Andrew, in your video on the antenna with out the dish, you do not mention any tubing inside the piece over the ridgid coax. In fact you show soldiering on the part made from old telescopic antenna to the coax. Could you explain why this is ?
dope I would like to try a pair if possible been using standard 2.4 ghz attys
Could four of these be arranged in an N,S,E,W configuration attaching to a common stem?
I would greatly like to test one of your pristine built antennas. Please PM me and let me know if this may be possible as I think your work is very educational and informal.
i have alfa cards and looooooove wifi antennas need and want to test one of your wifi antennas out would be the ultimate wifi experience.
Hi mate need your help ive gone fpv on my phantom useing 2.4 set up for fpv and 2 clover leafs work both on 2.4 and 5.8 but range is crap i know this because i used my mate £20 pne and range is bang on could i take them off and make my own clover leaf and re solder them back on
Looks great, have you just spray painted them to finish them off ?
Continuum Yes I use acrylic paint.
Trying to reach the shop ! but the link does not work,, do you have a new link ??
awesome!!!!!
Is this for a router or AP? Too bad you didn't show Visstumbler tests.
Ever thought about using plasti-dip instead of paint?
hello Mr.Mcneil i am working on a project i would like to know the source which you found the information on blade antennas
Hello sir, I would like to purchase two of these antennas. Please provide a link to purchase.
So both receiver and transmitter antennas must be of the same design? Or not?
I actually like it, actually ...
Does it work with GSM 900/1800 or UMTS 2100? Thanks!
MandRakeHD No sorry it won't
+andrew mcneil Why not? You should change the size. Lamda=C/Hz, Antenna size is Lamda/2 or Lamda/4.
C=299792458m/s and for Hz you can use 900 000 Hz or 1800 000 Hz.
+andrew mcneil I am looking for a homemade antenna por 900/1800, could you share some model?
How many dbi would this be?
I'm not sure if you have addressed this in another video so my apologies if you have. What coating do you use for your antennas? And how does it affect the signal gain?
I use acrylic paint and I also use plasti dip any effect on the performance at these frequencies are so small you would need ridiculously expensive test equipment to pick it up. So yes it will effect gain but you will not notice it. ;-)
@@andrewmcneil thank you both for the information and the quick response
Hi andrew, would be happy to test one on my long range quad if you have any left. Out of interest would this parabolic reflector idea work with an omnidirectional biquad?
robrow It would work but would have to be bigger as the wavelength for the biquad is 31mm @ 2.4GHz.
robrow Also send me an email and I will send you one. andrewmcneil@hotmail.co.uk
Can you do a video of this technique with a cloverleaf 5.8GHz ?
Now that's not a bad idea
please tell me the gauge of this copper wire.
How about vswr ?
By the way what is the software you using for Annalise the the antennas
+Luciano Junqueira Vistumbler
What about a parabolic helical for FPV goggles?
would this antenna work for a router
jason hernandez Yes but it is directional
Wouldn't it be safer to use something like beer/drink can for that?
+Winsucker They are not parabolas, also they are for the most part aluminium so you will be unable to solder. If you make sure it is empty there is nothing dangerous to worry about.
I can see that this video is bit old, but can this be made thin metal and plate? Just bend it in shape??
it would be hard to make a true parabola though
@@andrewmcneil didn't think that 🤔
But can it improve antenna at least little bit?
can you send me one for testing? 2.4 ghz tranmitter
can i have a pair please?
you paint it?
i need one.. :D but i live in Pakistan.. will you send the antenna
are you going to be selling these on your website soon I need 4 of them ? :)
Hector L I will be making some and adding them to the shop over the next 2 weeks.
sounds great I will be looking out for them at what price will u be putting them at?
