Product is exactly as described. Still running the hardware through it's paces, but everything so far has been great. Even though I chose the slower shipping method, product arrived within 2 weeks. Longest holdup was at customs in NJ. Shipping info was updated regularly and was well documented. I would definitely recommend this seller again and again.

Quality bit of test gear.

For NanoVNA V2 Plus4

As an owner of an original NanoVNA and NanoVNA2_2, really impressed. The larger screen alone is worth the upgrade from the 2_2.

Easy to use, good protective case and a sensible battery choice that is easy to source and replace as required.

The slightly improved specs over the 2_2 are a nice addition as well.

I use it on the bench connected to the computer and also at the feeding of Antenna's.

There is no comparison to the early NanoVNA's -which did have their place of putting a hobby grade instrument into the hands of many, but easily outgrown.

The value for money is very good and you can spend a lot more and not get much more in terms of performance.

A useful instrument to keep around.

Yes I am happy

For NanoVNA V2 Plus4

Yes I’m happy with this vna analyzer .
It was well packed and I did not have to wait for one month to receive it it’s getting way faster.
Everything was there in the box.
At least when you buy here you know you’ve got the real stuff, not a cheap copy with limitations.
You can find the correct manual on this site. Look for the forum about the vna.
So yes get it here.

NanoV2 Plus4 every ham should have one!

For NanoVNA V2 Plus4

A great tool, every ham should have one of these.
Easy to use, especially with the device connected to a PC
Comes with all the necessary connectors to do calibration (easy to do)
Once you download the instructions from the web, it's a simple process to calibrate the device and do simple SWR measurements.
If you really want to take more sophisticated measurements - then you can do that.
Don't be put off by the Smith Chart images looking to complex!, simple SWR measurements are VERY easy

Great product, minor out-of-box fail, refinements possible

For 4" NanoVNA V2 Plus4

I received this NanoVNA yesterday and while I don't yet have a lot of experience with it, this is my 4th NanoVNA and I am extremely impressed with the construction and the performance I have seen in initial testing.

However, on arrival, two of the three buttons do not function.
Fortunately the buttons are not absolutely necessary to use the device and I usually default to using the screen anyway.
But there are situations when I want to use the buttons and I need to have them so I have contacted the seller and will adjust the rating depending on the response received.

A few other minor points I'd like to see done differently:
- The USB-B port is very limiting. A USB-C port would have been much more modern, allowed faster charging, allowed the use of really common cables, smaller, no up-side-down insertion problems. (And of course added expense and complexity to the device, but still...)
- The housing is not labeled at all. The ports especially need to be identified but also the charging LED values.
- The accompanying stylus and calibration standards have no way to store them with the device. A side pocket or similar would be great here.
- There is no carrying or storage case with the device. Even if it were extra cost, an appropriate case of some kind would be very helpful.

The best NanoVNA available on market

For 4" NanoVNA V2 Plus4

It is clearly the best NanoVNA available on the market with very good performances for the price (comparable to very expensive VNA)
Congratulations for the good work and I'm impatient to see the future NanoVNA V3

Joop | June 30, 2021

Very satisfied with the product!

For NanoVNA V2 Plus4

The NanoVNA V2 Plus4 was delivered very fast and just in time for a short field day experiment.
Amazing how good the VNA works.
Have not tried al the possibilities yet, but I am already a fan of your product!
This piece of equipment will stay on the workbench for sure.

William | June 16, 2021

Extremely satisfied with the hardware and software.

For 4" NanoVNA V2 Plus4

I have really enjoyed the “Plus 4” version. I also have an official V2.2 VNA from Tindie but I am enjoying the enhancements of the Plus 4. The larger display is nice but the reality is that the most utility comes from connecting the unit to a PC COM PORT and using the software interface. This unit is quite accurate and puts a previously unaffordable piece of test equipment into the hands of hobbyists, technicians, and engineers. Thanks to all the folks who have made this possible.

I gave 1-stars for communications due to the fact that though I purchased both units from Tindie, Tindie failed to respond to my request for purchase price credit.

Amazing versatile instrument

For 4" NanoVNA V2 Plus4

Amazing capability for the price. If you know what it is and have things you want to use it for, great. Many buy it with no real idea of how or for what they'll use it, or maybe just to use it as an antenna analyzer. That's good too, and even better if in investigating its uses, it sparks learning and broadening of their understanding of RF electronics. The documentation, such as it is, is all on-line and not the easiest for someone just getting started. The UI can seem pretty opaque and complicated, but is actually pretty straightforward once you get a little bit of experience with it. Fortunately, there are many good You Tubes on operating it and using it in various applications.

Good prduct

For 4" NanoVNA V2 Plus4

The product arrived in the promised time.Good packaging.No troubles in start up and workin as promised. I am satisfied.

Great product, exactly as advertized, and hefty weight to it

For 4" NanoVNA V2 Plus4

This NanoVNA is pretty impressive. I use external software to run it so I can't comment on the screen, but the product has a nice weight to it, it is faster than the original NanoVNA, and gives predictable results with known DUTs.

Michael | Feb. 10, 2021

Fantastic Product for the Price

For NanoVNA V2 Plus4

Very nicely made. I've installed it in a 3d printed case also from Tindie from a French chap. The whole lot goes together really well and worked straight away. Clear comms and tracked shipping. Great supplier. Only small wish is that the V4 Plus was available. Not a criticism but it would be good if a few 'how to examples' were included in the on-line documentation for those learning how to use this great tool.

Cl | Feb. 4, 2021

Good product, but getting the battery is a headache.

For NanoVNA V2 Plus4

The nanoVna needs a LiPo pouch battery with a JST2.54mm 2pin connector, but this platform does not allow bundling the battery. This combination of battery dimension & connector makes the battery uncommon on the various online platforms. Even if you could locate one online, due to LiPo's transportation risk, you could be slapped with an exorbitant shipping charge.. So, if this battery not commonplace in your country, you will be better off ordering the nanoVna from nanoRFE's other platform (which allows bundling of the battery)
A word of caution: it is not obvious from the "features" and "specifications" sections that this product is NOT a true 2-port VNA.

Martin | Jan. 22, 2021

Well worth it!

For 4" NanoVNA V2 Plus4

The NanoVNA V2 Plus4 is my first low-end VNA. I've been considering getting one for a long time and have been waiting until I could get something with sufficient sample depth and dynamic range. As a first introduction to such a moderately priced piece of test equipment, I am very happy. In both antenna analysis roles as well as testing of filters and transmission lines, I have found the V2 Plus4 to be more than sufficient for my needs. The documentation on the official NanoVNA website is quite complete - if not as clean as more expensive test equipment. Any weaknesses in the official documentation however, is more than balanced by the blog entries and videos available across the internet. While my device has so far proven itself to be highly stable, with the open-source nature of the firmware and the PC software, I am looking forward to future improvements (further stability improvements, better calibration and added features) in the software. Overall I am wholly satisfied in my purchase.

Great product and incredible fast delivery to Germany

For NanoVNA V2 Plus4

Delivery from China to Germany was a new record for me. 3 days with TNT/Fedex. Absolutely fantastic.
Been using this product to get into SDR and characterize antennas, filter, etc. Have been using it for about two weeks now and had no issues so far. I have been working with full size VNAs before professionally and it takes a bit of tinkering to get used to the interface. Luckily there are many tutorials and youtube videos that teach you how to use it this device properly.

Stephen | Jan. 18, 2021

Great Device

For NanoVNA V2 Plus4

Simple to assemble and good online instructions. Solved many antenna system mysteries the first day. Why would anyone by an swr meter when you can get the NanoVNA? -Steve / N9WAT

Pierre | Dec. 30, 2020

Great product - Very Happy !

For 4" NanoVNA V2 Plus4

I have not yet verified the precision of the clock but went ahead already with adjusting a cavity filter and testing various antennas (ADS-B antennas are a big deception). Glad to have the enclosed battery, in the very nice metal case.

Operation through the menus are easy and TDR is also nice (I don't master every item of the various sub-menus and needed to look at the manual to get to TDR but that is ok) :-)

Printed my setting options on a piece of paper as to know where they are. A very slight improvement would be to allow for custom names for the various saved settings (those would need to be pretty long which would not be a problem since, when you are making such choices, rest of screen becomes irrelevant).

This is so much more portable than my 8753C... ;-)

Thank you !!!

Oh, and delivery took about a month to Canada. I was well aware of the delays so that was not a problem, even though I was somewhat surprised that tracking indicated a 12 hour flight from Ottawa to somewhere else... I just took the advice to "be patient" and it worked :-)

Rated the communications at the highest rating for lack of "not rated" option : There was no need to communicate but for the initial order itself.

All good!!!

For 4" NanoVNA V2 Plus4

I am still rewiew de nano vna V2 plu 4, I am reviewing the calibrations and I need to compare with a professional one I hope to obtain approximate results than with an R&S or a Keysight

Harold | Dec. 27, 2020

Excellent product

For 4" NanoVNA V2 Plus4

Did power up when charged 18650 installed, I needed to replace DW01 battery protection chip, everything is good now.
Worked excellent via usb otherwise. Happy to own this instrument.

Ivo | Dec. 26, 2020

Really good product! I can only recommend!

For 4" NanoVNA V2 Plus4

The Nano VNA V2 Plus4 is definitely worth for its price. Really. It is much more responsive than any of its smaller "brothers", I really appriciate a faster measurement time and also a better dynamic range - it is good for any kind of filter tuning (bending air core coils, etc.)!

However, I have some recommendation for you.

It would be GREAT if you enable the miniSD card slot located under the TFT panel for capturing s1p and s2p files...or at least for the screenshots. This device was tested by several HAM radio enthusiasts and they mostly complained to this particular thing.

Another one :-) Would it be possible to add a possibility to add more markers to the screen? To see the DELTA or add an automatic measurement of a -3dB bandwidth?

Martin | Dec. 26, 2020

Highly recommended!

For 4" NanoVNA V2 Plus4

This little gem is amazing! It does many things like its 100 times expensive brothers with astonishing accuracy! Just installed the battery and performed the SOL calibration and I am ready to go. Expecting some firmware mods to enable more options but all measurements can be done now! My $130 were really well invested!

Excellent instrument for DIY antenna makers

For NanoVNA V2 Plus4

My interest in the NanoVNA came from needing to analyze antennas for radio control models. In the couple of weeks I've been using it, it's proved to be a very useful tool.

Of particular value to me is the ability to connect the NanoVNA to a PC and save screenshots, an output file of an analysis, and calibration settings. Connecting the NanoVNA to my Mac was straightforward. Likewise, I had no trouble with either the NanoVNA QT software or the NanoVNA Saver software. The latter is more more powerful. It quickly became my preferred way to use the instrument.

I don't have access to lab quality equipment to confirm the accuracy of the NanoVNA. However, there's at least one online review that does so -- with favourable results. I can say that the readings from my unit are consistent with those from a handheld PS100 antenna analyzer.

If you don't have a calibration set, be sure to include one in your order. It's an essential accessory. Likewise with the test leads. I ordered the plastic enclosure, too, and was glad I did. It provides some protection for the unit. Assembly of the case was straightforward. However, I did need to take a needle file to a couple of the plastic tabs to allow them to fit in their mating slots. It was a trivial job that took just moments.

The shipping time to my location was perfectly acceptable. I ordered on Nov. 14. The package was delivered to my door by courier on Dec. 4. There were no difficulties with customs. I've found that orders from online retailers in the US can cost more and take longer to arrive.

I had no need to contact the seller. Tindie's order confirmation email arrived promptly and contained all the information I needed to feel confident in the process (my first order from Tindie).

In summary, I'm very happy with my NanoVNA purchase. In fact, I've already recommended it to others.

What was once pure guesswork is now visible !

For NanoVNA V2 Plus4

I watched Speiss on YouTube showing his old 1GHz VNA which I thought was alright but not really tremendously useful until you can get to WiFi at 2.4GHz. So now that these newer versions go up to 3GHz I knew I had to get one. (Speiss has since upgraded to this 3GHz one and done some good videos on it. So in lieu of any missing documentation, there are many videos of people telling you how to use it).

Shipping was quicker than expected and it comes in a small box. I opted for the case and calibration kit. Now that I have it I can say that the case is very useful and I would recommend getting it. The calibration is utterly essential to having it work at all. Unless you already have a calibration kit do not skip buying it.

Building the case is fiddly but doable. You have to be careful about the orientations of all of the parts but once done its pretty neat and fits around it well. I think it protects it quite a lot and makes it easier to handle - but its not absolutely essential.

The cables that fit to it are great and of good quality and the calibration kit works well. You need to supply your own USB C lead so make sure you have one ready.

The UI on it is perfectly reasonable but it takes a bit of reading and watching YouTube vids to get the hang of exactly what it needs or is showing. But once you get to grips with it then its a great little device. By no means an advanced pro device, but lets face it, what was once many thousands of bucks is in your hand for a few tens. You can finally see a Smith chart for your antenna and get SWR readings with a frequency sweep at WiFi frequencies. It works, it works well, and its amazing. This is a must have bit of kit for any Ham Radio enthusiast or someone working with radio modules / antennas. You may also need to buy in a set of various SMA male / female and RP style adapters to hook up the different WiFi antennas to the leads. Just be aware not to try to connect an SMA to an RP-SMA connector such that its actually open circuit - because there appears to be no standard.

Great to check and improve your Antennas

For NanoVNA V2 Plus4

I saw the NanoVNA in Andreas Spiess his Video #359 How to properly use a NanoVNA V2 Vector Network Analyzer & Smith Chart (Tutorial)
And knew I wanted one. I use it to check/modify and build my own Antennas. https://youtu.be/_pjcEKQY_Tk I can say it improved my overall Antenna qualiy quite a bit and have reached notably better connections since.

Surprisingly smart

For NanoVNA V2 Plus4

I'm using this device for measuring UHF and VHF filters. Tried also some antenna measurements. I am relatively new to rf electronics, but this little, cheap and handy meter is very good member at my workbench now. The only problem I have got, it does not communicate with PC. It worked just one time. Now the device appears in the list of connected devices,but still don't work..I am trying to find the problem, maybe Bad usb cable. Driver installed. Powering it from Li-Ion battery 1600mAh from old smartphone.. Will post again as soon i resolve the issue..However-very good buy!

Nice NanoVNA & Quick Delivery

For 4" NanoVNA V2 Plus4

Very nice NanoVNA with a nice metal case. I installed a 18650 LiOn battery and everything seems to work OK. The cables seem good, however in the SMA cal kit provided the 50 ohm SMA load measured 50.931 ohms using a new Keysight 34465A 6 1/2 digit DVM (need to request a better SMA load). Shipping was quick, much quicker than the things we get from AliExpress!

Documentation is on-line, as is communication, so not really able to properly rate either.

Overall very happy with my first purchase from Tindie!!

Best,

Mike

Nice VNA for a nice price

For NanoVNA V2 Plus4

So far this nanoVNA_v2 has been everything described. Its kit-form case was fun to assemble but fits well when done. Tindie also had a 1000mAh battery with the correct connector that fits perfectly and provides plenty of operating time after charging. The included calibration standards and SMA cables are sturdy and work well. Fortunately I already had an SMA/UHF adaptor to measure my amateur antennas and the readings made sense. The VNA also works well with a nanovna-saver linux application if run with root privileges. Its online manual has the needed information to get started but could be improved with application examples. The NanoVNA_V2 seems to be good value for measuring rf properties and antenna characteristics.

NanoVNA V2 works 100%

For NanoVNA V2 Plus4

Tested a number of antennas using the NanoVNA. Excellent results when scanning over a wide frequency range. Found a number resonance points beyond the expected frequency.
The only request for a change is to make the letters and number a little bigger. I'm no spring chicken so the eyesight has problems reading the display.
