I have been using a nanovna for a couple of years and have found it very useful for tuning and troubleshooting antennas. Every time I use it I am amazed that such a cheap tool can give me the same information as the $80,000 analyzer I use at work. Obviously I don't expect it to be perfect but I have compared it and found it surprisingly close.

I agree. When the first cheap devices appeared on the market, I had suspicions and also compared it with an expensive instrument. Already then, the results were usable for my purposes.

That does it !!! It's 40 years since I used a Smith chart. 15 years working with HF/VHF/UHF antennas with the old tools. What would we have given for tools like that? Yes, I see why you fell in love with it! I'm off to your Patreon channel - give us more like this.

They do, or at least they try. But it's presented as if you're an electrical engineering student. That's doesn't work with everyone. Definitely didn't with me, and I spent a career in technology.

Great video again, I will have to have one of those analysers, I was brought up on an HP VNA and have seen that the price of professional equipment has tumbled down in recent years. Remember the Anritsu Sitemaster? So helpful to have the comparison with a 'known good' analyser - better than any sales pitch. Now, what would be interesting (because you like testing outdoors and now have the tools) it would be really interesting to show the impact of antenna optimisation on your radio link budget in real terms of RSSI. Again, great video, keep it up. (Ian T) :-)

You have really showed us how we can optimise our own antennae using tools that even we hobbyists can consider getting. Thank you again! One question please Andreas, please could tell us if this device can be used for wifi/ES32/ESP82xx, GSM and other similar modules that all play with. I know you said that the 2.2 GHz band is covered, but is it just as effective in that range? Sorry if I missed this the video but it wasn't clear to me. Ps.

This is not a newer model, it has more features. But I do not know it (ant the software coming with it). I bought the miniVNA instead. Just for antenna tuning, I cannot imagine you would see a difference between the two because you do not need the second port.

Andreas, thanks for the great video. I think it would be a nice idea to set up a website where the performance, or resonating frequency of these antennas is documented. These VNA tools are still quite expensive for the regular maker, also because you usually have to pay custom fees for more expensive items. Maybe a simple public Google sheets will work for this, or a Google sites website?
