I would suggest drilling holes for elements half a mm smaller so there would be friction holding elements in and to use some super glue too just in case
You make my maker life so much better by sharing wealth of knowledge! PS I do hope TH-cam is paying you handsomely? No less then 16 ads they played during this video. Cheers, no ads can stop me from gathering the wisdom you share!
Oh yeah mate... going to try making one....even if it doesn't work...it'll look bloody killer ;) PS: ..and the suction cup on my dual 2.4 curved reflector is still stickin' there Sir ;) May You & Yours have a very...merry....ummmm....whatever @ this point Mr McNeil ~Whirled Peas
not sure if you guys cares but if you're bored like me during the covid times you can watch all the latest movies on InstaFlixxer. Have been streaming with my gf for the last couple of weeks xD
a way to speed up the production of these, is to buy a 3D printer, print the aluminum part of the antenna, and cast it out of aluminum using the lost pla metal casting method.
?What is the center frequency design point of this antenna? Did you choose center frequency=2.437GHz for the US WiFi channes 1-11? or did you select center frequency=2.450GHz to include all 14 channels for worldwide "2.4GHz" WiFi? (or something else?) Also, if not too much trouble can you cite the formulae or tool you used to calculate the dimensions for all the pieces? Thanks.
Having difficulty locating your template for holes in yagi plan as you described at 47 seconds into video. Cannot find it in the link below as stated. Can you point me to it's location please.
Small diameter tubing is very easy to cut with a hack saw. There's not much difference in total time between the two methods. Plumbing tube cutter is cleaner, but takes a little more time to cut. Hack saw cuts are faster, but need time to clean. ;)
What's the best model of antenna for 2.4Ghz of all you have done? This one or the Yagi Panel? Why we look for a V shape in the spectrum analyzer? Thanks
He mentions in the video a template would be in the description...yet.. this seems to be lost in translation... I'd rather ask.."Any for sale?".. and that's where the Ebay link looks like it will come in handy dandy. I'd love to have 1 of these built by the master.
You can make your own. Search for an online Yagi calculator and use it to find the element spacing. It will be a little different because of a different driven element, but still very good.
I bought a Yagi from china that was advertised as being for 2.4ghz and 16dbi with the intention of using it for FPV on an antenna tracker but having stuck it on my NanoVNA V2 which ive just got, the antenna is only good for 1020 and 1980mhz, is there anything that can be done to re tune it or is it only good for the bin and should just build one?
@@andrewmcneil After learning a lot from your videos, thats what i feared. I didnt want to trust it till my NanoVNA arrived and it sat for two weeks, im glad i never tried to use it as a dead video transmitter would not be funny while in flight even with return to home as the same link is also what carry's my telemetry and it would be a totally blind wait to see if it came home lol.
@@stevefox3763 Since the resonant frequency is low, the elements are too long. Theoretically, you should be able to cut the elements shorter to reach a higher frequency. But that's a lot of work to get it to the exact frequency you want. It's probably easier to send it to the bin and build one to your exact specifications.
@@Texas1FlyBoy I haven't binned it and have nothing to loose by attempting a re tune, the folded dipole is the part that will give the most grief but I could simply re make that element rather than trying to modify the length of the existing one and the rest of the elements are just a 30sec hacksaw job for each one.
Ha ha ha? I was just about to comment? Saying this looks like a old video! Just had the look and feel of one of your older video's. So forgive me, as i just happened to read intro. when i was waiting for advert to finish...lol...So the advert was useful for once....ha ha ha ha
If you're going to provide a template, then provide it in a location that doesn't require joining special groups, websites, etc. Also, provide a drawing of the template with dimensions in the video as redundancy. You put so much effort into the video, and it would require so little effort from you to make things so much better and easier for your viewers.
Its crazy how accurate you have to be when desining & making these antennas? Makes you think how all these cheap made chineese antennas work? Well im semising there as they probally dont work! Ha ha ha. I bought a Alfa when they were the DOGS!! I bought from what i thoiught was a legit store. It kept on dropping out, i took apart and the soldering was like a school kid done it? Well? School kid would of done a better job! The ground on the sma WAS TERRIBLE AND SIGNAL CONNECTION WAS A BLOB of solder.(sorry bout caps) Ohh? Also a coil was cracked in half Live and learn, but i was gutted cos i new how good they could be? So i didnt have no fun with it. Although probally better i didnt? As i would of got into trouble probally?...ha ha ha ha h
I love the construction techniques!
Much to learn on this channel!
Much joy to everyone this holiday season de N2NLQ
Glad you enjoy it!
@@andrewmcneil please conclude for me that which 2.4ghz directional wifi antenna is the best in performance. Would if you rank them.

Please link for template download Sir
Sir you are hard working for us
A very cool design. In the beginning, I was thinking you were making a cubical quad.
not sure if you guys cares but if you're bored like me during the covid times you can watch all the latest movies on InstaFlixxer. Have been streaming with my gf for the last couple of weeks xD
@Santana Mayson definitely, I have been watching on instaflixxer for months myself =)
@Santana Mayson definitely, I have been using instaflixxer for months myself :)
@Santana Mayson Yea, I have been using instaflixxer for since december myself :D
@Santana Mayson Yea, have been watching on InstaFlixxer for years myself :D
Also you can use nutserts for the thread for the tripod .
Good work Andrew.
Glad you enjoyed it

Hello and thanks...Where is the file to download?
I put the yagi on the electric hotplate and fill the holes with solder.
a hero
Could you put brass slider tubes on the little wings (ends) on the driven element and adjust their length that way?
Thanks for another fun project!
Cool idea!
Good job sir ...
Thanks and welcome
How thick is the paint and what is the dielectric constant? Did you test the yagi after you painted it/capped it? I realize the paint thickness is
Loved this explanation. Did you try it with a smaller square boom?
?What is the center frequency design point of this antenna?
Did you choose center frequency=2.437GHz for the US WiFi channes 1-11?
or
did you select center frequency=2.450GHz to include all 14 channels for worldwide "2.4GHz" WiFi? (or something else?)
Also, if not too much trouble can you cite the formulae or tool you used to calculate the dimensions for all the pieces? Thanks.
Awesome!
Will be available for shop? Good holidays thank you for sharing knowledge
Having difficulty locating your template for holes in yagi plan as you described at 47 seconds into video. Cannot find it in the link below as stated. Can you point me to it's location please.
have you tried using your drill press as a lathe for cutting and cleaning up the ends of your tubing?
I am wondering why you don't use a plumbing tube cutter to cut your tubular aluminum elements? That would seem to be easier than hack sawing.

Awesome YT. Great job! Is there a spec sheet or PDF or template that I can download somewher?Thanks in advance!

I'd rather ask.."Any for sale?".. and that's where the Ebay link looks like it will come in handy dandy. I'd love to have 1 of these built by the master.
Ebay store = non existing.. oh how the supply/ demand equation is playing out here...much want....not much yaggi..
If I built this antenna exactly to spec but added length and additional elements at the front end, what would be the affect?
I was trying to find the templates online but they don't appear to be there anymore. Could someone attach them here?
Baking soda works great for removing super glue.
Yes it does!
Hello Sir, where can I download the template for this beautiful antenna?
love try this antenna. but I cant find the link for the template.
You can make your own. Search for an online Yagi calculator and use it to find the element spacing. It will be a little different because of a different driven element, but still very good.
Would solder be better than super glue?
Looks nice. What's the range?
The link for the design isn't there.
sir ...please try 6.3 cm. Who is better
Has anyone scaled a DB8 TV antenna for operation at 1296MHZ to 7GHZ
How can i do it for 230-380 range ?
do i need to ground the directors and replectors or not? please help
No. Just make sure they are glued into place.
template please for holes
Does it have to be 3mm tube? I have 3mm tig filler wire.
It does not need to be tube. Filler wire should work. I use solid aluminum wire and it works great.
I bought a Yagi from china that was advertised as being for 2.4ghz and 16dbi with the intention of using it for FPV on an antenna tracker but having stuck it on my NanoVNA V2 which ive just got, the antenna is only good for 1020 and 1980mhz, is there anything that can be done to re tune it or is it only good for the bin and should just build one?
Sad to say but bin it

How'd it work out?@@stevefox3763
is the gain as good as the turbotenna?
Yes
How come you aren't testing actual distance and channel reception?
Now use that in cantenna
It would not work and my next video will show you why
Where could we stumble upon this illusive design/ measurement template?@@andrewmcneil
Ha ha ha? I was just about to comment? Saying this looks like a old video! Just had the look and feel of one of your older video's.
So forgive me, as i just happened to read intro. when i was waiting for advert to finish...lol...So the advert was useful for once....ha ha ha ha
To be honest I completely forgot about this design it was supposed to be a stepping stone to a circular polarized Yagi.

You should get a new camera, your videos looks like old videos (saturated), else is good..
Yes. As he stated, this *is* old video from several years ago.
Its crazy how accurate you have to be when desining & making these antennas? Makes you think how all these cheap made chineese antennas work? Well im semising there as they probally dont work! Ha ha ha. I bought a Alfa when they were the DOGS!!
I bought from what i thoiught was a legit store. It kept on dropping out, i took apart and the soldering was like a school kid done it? Well? School kid would of done a better job!
The ground on the sma WAS TERRIBLE AND SIGNAL CONNECTION WAS A BLOB of solder.(sorry bout caps)
Ohh? Also a coil was cracked in half
Live and learn, but i was gutted cos i new how good they could be? So i didnt have no fun with it. Although probally better i didnt? As i would of got into trouble probally?...ha ha ha ha h
I bought one of those $15 yagi's from china and it was pretty crap. when you took the plastic caps off the elements they were all over the place.
