You create very good content. You could do a comparison material of NanoVNA and tinySA with your equipment because these devices are available and cheap. I think it could be very interesting such a comparison with professional equipment.
Awesome how you connect between empirical and theoretical! And, pretty slick how the calibration setup works! I imagine that it can also be done by using a short, open, and 50R dummy load at the feedpoint?
Wow man, this is a very great video. I've never seen something like this. Waiting for the next antenna simulations. Can you simulate a Helical antenna for 915Mhz please? Thank you very much. In the case of phase trace, how to improve it to match 0º over the frequency you projected with the return loss? I have a NanoVNA that I use to simulate my Trace antennas on a PCB and it is working good for me. And how you calculated the balun of the antenna?
4NEC2 has a helix helper in the geometry builder, I think you can easily simulate helix antennas there. To shift the antenna to a lower frequency, we can make it with a longer wire. Take a look in my article: gusbertianalog.com/loop-antenna-design/ For the balun I just went with what I had here!
Sometimes people have access to this kind of equipment through their employers, but don't get much training on how to use it. That's why this is valuable.
Thanks. Also, important is to grab the basics of how to perform the measurement.. In the next video, we are going to characterize a crystal, which depends on a careful config of the VNA.

Great content . This channel deserves more recognition
Thanks for the support!
I've been screwing around with MMANA-GAL but the parameterization in 4nec2 is really what I need. Thanks for the video.
It is a powerful tool, it can get you very far.
I made some for UHF for the TV, I used all my galvanized metal hangers, it worked really well... good video, good content.
Amazing! The video is fantastic. Thank you for always sharing this rich knowledge with us.
Thanks! Glad you enjoyed it.
He is back 🤩🥳 Amazing content as always!
Welcome back. We missing you
Hey Gregory, excellent video and great content. Thanks for your hard work and all you do for the electronics community! RF Man
Thanks!! 😄😄

Nice!
Very nice! And very nice Keysight unit to check the results of the simulation. I use CST to simulate and also MMANA-GAL. Thanks!

🙏🙏 Yes, it could!
Amazing video!
Thanks!
Thanks for the really detailed use of the FieldFox!
It is a great tool, I love it!
Good content. Thanks.
Gregory é o melhor do Brasil eletronica na vêia, o a cara é muito fera....
Thanks!!
Fala Gregory. Quanto tempo! Que bom que voltou, como faço para comprar seu curso de transistores MOSFETs da Hotmart?
Heck yeah, new All Electronics!

@@AllElectronicsChannel what about the skin effect of the wire thickness?
For this case, if I'm not wrong, it is possible to place a load element in each wire.
👍nice video. Well done
Thank you 👍
Já existe data para abertura de vagas para as próximas turmas de cursos da Hotmart?
Também queria o de MOSFETs
Also, slot antenna - very similar to the loop, but with gain.
saudades dos videos do meu macho
Great❤
Wow, I always though the Null of a loop antenna was on the broadside.
That is the case for small-loop antennas!
HueBr spotted! O agente laranja vai te deportar! Great video!
Soooo... are there any hacks, to check simulation vs real-world results, if you don't have the money to front up for a fieldfox?
A NanoVNA will show you the return loss, perfect for learning purposes. Much less than a field fox.
@@stuartmartin3408 Also far less accurate, and far more misleading.
@ not in my experience comparing them to expensive equipment, for learning purposes they are satisfactory so long as you do the OSL cal properly.
I never tried the NanoVNA, but it looks like a great alternative!
Parabéns
73!
Du caralho!

Does one in ten million people have USD50,000 to dick around with this expensive equipment in their basement? Yet, over 1200 views?
Hahahahah

Não é real, deve ser um video gravado po IA

Tudo isso pra fazer propaganda desse VNA de playboy?
