[@carldavis8228]

From what I see in the comments and having bought one myself. The folks who sell this VNA should as least pay you as an instructor if not for the boost in their sales. Thanks for another set of helpful insights in both using this device and our equipment.

@David Hogg How do I get on the "IO" forums? And how can I get one of the good ones (Noelec? Hugen? Deepelec?)

[@AlessioSangalli]

Not everything has to be about money.

[@wb7ptr]

The only complaint I have about it is the the manufacturer hasn't provided more detailed instructions for it's use. A lot of the purchasers are NOT engineers. A lot of ham radio operators are buying these. Some are engineers and some are not. I think a professional engineer would get the hang of it pretty quickly. The rest of us need a bit more help.

[@fourfortyroadrunner6701]

Absolutely stellar. I'm 75, have forgotten a lot of what I thought I used to know. ETR2, USN, 68-74, NAS Miramar, 70-74, maintained GCA RADAR and TACAN, unfortunately all old tube stuff back then. 9.8ghz RADAR

[@BritishBeachcomber]

The best NanoVNA tutorial I've seen.

[@adriancressy8363]

THANK YOU. I bought one of the NanoVNA from Amazon and got the "upgraded" unit. The accuracy of these analyzers will help the operator to get the most out of their system to the distant station. Many analyzers are not very accurate and optimization of the antenna system is not even close.

[@adcrane]

One of the clearest, most concise videos I've seen on the topic. Many thanks for your clear explanation.

Everyone else presenting this confused me, and left me with more questions than answers. THANK YOU for straightening it all out in 6 minutes!

Ambiguity tolerance is my friend. With a little help from inverse osmosis, and watching this finely crafted video five times, I see what you are saying. Great video! Thanks and cheers!

[@NeilWaybright]

This was a delightful intro to a lot of the functions of the Nano VNA interface. It is a powerful little tool, but the UI isn't always intuitive. This was very useful to me.

[@christopherpaulin5548]

This is the best video on the internet on how to use a NanoVNA to sweep an antenna system for SWR. We've shared it with our club. Thanks for taking the time to make these videos

[@mnmmnm6718]

I get amazed everytime I see your videos, a True Electrical Engineer at its best,

[@johnmarchant9253]

A great informative video which has solved a lot of the uncertainties I had with the NanoVNA as I only wish to measure the SWR of my loop antenna at different frequencies to enable the pre-setting of stepper motor positions.

[@PowderMill]

Thanks for the video… David, you’re the best teacher I’ve ever had in the RF/Ham fields. Your duplexer tuning videos are still used as review material every time I tune one.

[@martindawe2934]

This video is a very concise and easy-to-follow step-by-step instruction on how to measure SWR. If you pay attention you will start to learn the UI of the NanoVNA and get a feel for how to make it do other things. W2AEW, you did a very good job. Thank you!

[@artur19846]

Just got this magic tool! It's so amazing it has taken me away! A must-have for any beginner radio ham! I wish this device was used at physics lessons at school.

[@ka9dgx]

That really helped me understand what the controls on a tuner do, as you said... thanks!

[@brentjohnson6654]

Thanks for the video. I haven’t used a nanoVNA for a year and was not settling it up correctly. Now that I know to highlight the trace to format it all works much better.

[@bigoper]

Well, NO IDEA WHAT YOU WERE DOING, but!!! loved every second of it (I know nothing about Antennas)

[@danny_mixmandan_james]

Just brought one of these and to say mind boggled is an understatement! Brought it to check the SWR and tune my loading coils on my Diamond CP6S - at least I know sort of where to start as never used one of these before - always adjusted, gone back to the radio and checked the SWR - just trying to work out how to connect the PL259 to it! It’s one of those small adaptors that came with it... I hope!

[@w2aew]

It likely did not come with an adaptor for PL259 - you'll have to pick one up yourself. The bits it came with are likely the Open/Short/Load and Thru devices that you use in the calibration process.

[@paulkeeton6512]

Great video! I bought a NanoVNA and was looking for info on its use. Looks like I found it! Nice job!!!😁

[@billmungaven-n6ef]

Bill-N6EF-Thanks for a another great NanoVNA video. I'm learning a lot about the NanoVNA from your videos. I never really understood the value of the Smith chart until I saw how you used it in this demonstration. I usually turn it off and only look at the SWR trace. I will be experimenting with my tuner using the VNA to get a better match other than SWR.

[@g0fvt]

One of my first “experiments” with my NanoVNA was with the ATU in a similar way, it took a while for the penny to drop, RF path in the ATU is relay switched and had been unused a while. Needed a bit of real RF current to clear the oxides. NanoVNAsaver is a must have software to grab plots. Thank you for another great video.

[@billjones2271]

Thank you for the software info!

[@g0fvt]

@@billjones2271, talking measurements with the NanoVNA at home the PC software is in my mind a must have. The plots can then look very professional and of course you can screengrab them. I have been doing some measurements with baluns, the ability to actually save a sweep and print it has transformed the process. 73

[@keithbanner8818]

Just wanted to say thank you for showing me how to setup and check my swr's using this meter.

[@billygamer3941]

This and the other videos here on the Smith Chart function of the NanoVNA are greatly appreciated. I wonder what Phillip Smith would think of the tools now available and that his chart still is relevant. Also, I am glad that you cautioned about calibration using the OSL method.

[@mikejohns3104]

Good demonstration. Tuners make more sense to me now after seeing this visual aid demonstrated on the vna.

[@billpowell5931]

As always, clear explanations and visual pointers. I am interested in getting one of these VNAs, but I am still studying the options. So many variations... Thanks for sharing.

[@w2aew]

I went with the NanoVNA-H4. The NanoVNA-F has a similar sized screen but in a metal case (nice). There is a new v2 that is just coming out now that goes to 3GHz. Firmware is a little behind the original (doesn't interpolate between calibration points - thus you have to calibrate with every frequency setting change - good practice to get into, although this forces you to do it).

[@EngineeringVignettes]

I try not to mention other channels normally but TomTekTest (TTT) just put out a comparison video on the NanoVNA options about 30 min. Prior to this comment. I have not watched it yet tho.

[@TianarTruegard]

A nice simple video on the Nano VNA. I've used mine for measuring antennas, but I have yet to figure out the other traces beyond plotting SWR on it. I purchased my Nano VNA to measure SWR on my antennas before using them. It would be nice to learn its other amateur radio related uses.

[@geekthesteve6215]

Great video. I am working on a 2m Isopole that is missing the cones on the main element and and the radials on the ground plane. You showed me how I can read the smith chart to determine capacitive and inductive factors so I can hopefully make new parts and get this antenna tuned better than the current 2:1. Thanks!

Again great Video. Watching your network analyzer/Duplexer video, I adjusted a inexpensive duplexer to notch out the upper image frequency of a 2 meter radio. Now no intermod interference. Thanks.

[@rfburns3472]

Excellent video! I replicated your setup and came up with nearly identical readings using my old Denton tuner. However, as expected, when connected back up to my transmitter, the tuner had to be slightly readjusted to get the lowest return loss. So, while it is an interesting experiment, its not safe to assume the tuner has a good match with the transmitter after completing the VNA observed tuner adjustments.
