Merry Christmas and thanks for the video Andrew!! 😁 I don't know if this makes me a sad person but I enjoyed the break from the festivities and watching this. 🎅, 🎄 I very much liked that you showed it not working first time. This showed, the problems which can occur, how to deal with them and a final result. This is such a nice change from "perfect" construction videos where the viewer is left feeling stupid if theirs doesn't work first time. More like this please and compliments of the season to you and yours! 😄,👍
I've seen people put a little computer fan behind where they are working to suck away the flux fumes, maybe that's enough to stop it going straight up your nose
Can't help wondering if this design is intended to live inside a PVC tube, which will push up the response closer to the WIFI band? I think your plans for the brass tube collinear in another video showed a similar too low response with the exact dimensions from the plans.
@ANDREW - Perseverance pays off. Superb !!! - I would really love to see this modified for the 3G/4G phone networks,... as 3-Mobile - awkwardly sits in the band of 1700Mhz - 1900Mhz and their coverage is negligible to zero in my location. (Not having a network / VNA to check the 'curves' makes any attempt to TUNE any antenna difficult) .
Given the difficulty of accurately bending the coils could it be made easier by using multiple strands of thinner copper wire bent round a, say 3D printed, form? Merry Christmas Andrew, all the best for a quiet "less restricted" 2020.
Nice experimenting. It is a real boon that experiments like this are sharable and I'm grateful to be able to "virtually be there" with you while you did this. That said, I am curious about something: at 12:17 and 18:50 into the video you show the test setup with the antenna rising off an elbow connector so that it is vertical but adjacent to the lower element section is the "detector" housing which is also vertical, parallel, and immediately adjacent. Doesn't that affect the tuning of the antenna? It seems like you could rotate everything so that nothing metallic is immediately adjacent to the antenna that could influence it (approximation of a "free space" model)? Perhaps you observed while doing that and can say?
Why don’t you use a solder stop end (cap) on the end of the pipe that you attach the sma connector to - must be easier than soldering sheet to the end?
This question may have asked before but... Can I attach a single band wifi antenna to a dual device without fear that the device will be damaged if dual bands are sent toward the antenna? Will performance suffer on the single band? If I cannot disable the unneeded band in software, how can I terminate or filter it on the wire?
15:50 You shouldn't have your test equipment (power sensor and cable) running parallel and adjacent to the Antenna Under Test. You cannot reliably get trustworthy results with that arrangement. The antenna being tested should be up and away from things (at least a couple of feet, YMMV), and likely would be best to have a ground plane under the feedpoint. P.S. belated Merry Xmas.

Happy holidays everyone 🎄🎄🎄🎄
Same to you. Thanks for your videos
Happy Holidays and wish you very happy New year 🎉🎉
Merry Christmas. Interesting getting their in the end. A lot of cellular commercial antennas are stacked dipoles of similar design. Nice one.
Merry Christmas and thank you very much for sharing your knowledge with us .
I am addicted to radio stuffs . 😬😬
You put the great efforts to get it done and finally achieved that result, well done happy to see that curve for 2.4 Ghz😊
Thanks Dev I did enjoy this one 🎄🎄👍

You need to consider L/D of your element construction. At these freqs the effect is dramatic, as youve shown

Andrew, I really like your decent builds. 👍👍
Good job sir ...keep it.......................

thanks you-Happy New Year
What would happen if you had a three.turn winding?
It would add more capacitance so it will change the frequency and you would have to reduce the measurement

.
Curious as to how the antenna would perform if you removed the top copper pipe piece
Excellent explanation, thank you very much

I hope so James 🎄🎄👍
I meant 2022 of course.

Yes you can wifi devices do not generate the power required to course damage to a device do to antenna mismatch.
Meander dipole construction antenna homemade. Merry chrisman

is that any better than the standard 3-5 db rod? Why do you not tell us how to MAKE the long TP LINK antenna, including the capacitors?
So, how do you calculate the loop lengths and bend radius?
Hi, What is the best long range antenna for 2.4 wifi which can receive the signal from a 1 km a way?
MC and 700MHZ directional pleaseeeeeeeeeeeeeee?
Merry Christmas 🎅 🎄 ❤ dear.... wishing you a wonderful life in the coming year 🙏... appreciate all your work...
