Nathan | June 12, 2024

It arrived relatively quickly and it works just fine so far.

For 4" NanoVNA V2 Plus4

I chose the cheapest shipping option: 4PX Logistics SF e-parcel (Tracked) on 25 May, 2024. I received emails stating that it had been ordered on 25 May, 2024. It arrived at my place in Idaho on 11 June, 2024. I received emails stating that it had been shipped on 28, 29, 31 May, 2024. I've used it very little so far. It didn't come with a battery but it works just fine when it's plugged into a USB. I downloaded both the NanoVNA-QT & NanoVNA Saver software on my PC with Windows 10. It connected just fine.

Great product for the hobbyist!

For NanoVNA V2 Plus4

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.

excellent VNA!

For 4" NanoVNA V2 Plus4

VNA enclosure and hardware build is excellent! Excellent customer support even 1+ year after purchase :)

Works well, but needs a User Manual

For NanoVNA V2 Plus4

I have used this to measure various antennas, and it is useful. I also used it to measure an RF attenuator.
With no manual, the proper setup, and proper calibration procedure, is guess-and-hope. (Do I terminate both with a 50 ohm load, or just input 0? How do I null-out the length of the cables?) What else can this tool do?
But overall, this is a good tool, and definitely worth the price.
Thanks!

Love this VNA, but

For 4" NanoVNA V2 Plus4

Mine has started to shut down and it is not a battery problem. Any ideas?

Also, I have heard about a firmware version to support crystal measurements. Is this going to be included with future units?

Response from HCXQS group | Jan. 11, 2022

Hi, can you tell me more about the problem? Is the battery fully charged? When it shuts off does switching it off and on again work? You can contact us by clicking "message seller" on the right side of the page. Thanks

NanoVna V2 plus 4 delivered today

For NanoVNA V2 Plus4

I received my nanovna V2 plus 4 today, and have the classical (seen on the forum) problem of battery. I had bought in advance a 18650 battery... but in fact its length is about 5 mm too big (it includes a protection.... ). So, it could be useful to insist on that problem (choose the right 18650 battery !! with a warning) on the vendor site.
Without battery I plugged the nanovna to the usb port of my computer and it seems to work well. I can begin to play....

About the shipping: the item was ordered on november the 20th, shipped by SF eParcel and delivered (in my letterbox in France) today on december the 18th. So a delay of less than 3 weeks from China to France, which is very satisfactory.

Thank you to the team for the good job !

Response from HCXQS group | Dec. 18, 2021

Thanks for your review, we have now updated the description to clarify that an unprotected 18650 cell should be used.

After about 1 Year, Damaged ESD ?

For 4" NanoVNA V2 Plus4

Great measurement equipment used it for 1 YEAR. When measuring an HF antenna it stops measuring and do not calibrate above 100MHz.
Maybe the cause should be ESD or something with the PLL generator above 145MHz.

Do you have some clue based on others related problems??

For repair input switch or ESD protection diode do you have spare components you can sent.
Thank you
Fernando

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.

Andre | Nov. 9, 2021

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.

Geoff | Oct. 18, 2021

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

David | Sept. 7, 2021

Excellent in all respects!!

For NanoVNA V2 Plus4

You have outdone yourselves!! Absolutely excellent from performance to packaging. This gives any and all "antenna analyzers" a serious run for the money!!!

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.

Very disappointed that the main CPU does not have FPU.

For 4" NanoVNA V2 Plus4

Received the NanoVNA V2 Plus4 well packaged and delivered before the expected delivery date. Thank you.
Very disappointed that the main CPU in the VNA does not have the Floating Point Unit (FPU) as previous units do have them. They should be advertised as not having the FPU and sold for less. The addition computational speed on a VNA would be a great benefit.
Will these VNA units be replaced??
Not happy!!

Response from HCXQS group | May 21, 2021

Hello, all VNA calculations use fixed point math and do not use floating point. The developer verified there is zero difference in measurement speed with or without FPU enabled, so it is disabled in all firmware builds. The sweep speed above 140MHz is always 400 points/s. As FPU is disabled in all firmware releases, it will make no difference if it is present or not.

Gianfranco | May 16, 2021

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.

Richard | May 15, 2021

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.

More measurement points

For 4" NanoVNA V2 Plus4

Hi

Using the 4" NanoVNA V2 Plus4 with all my amateur radio gear, the VNA is working very well but I'd like to have more measurement points than only 101. I know a complete scan, of several MHz, then would take much more time, but still 10.000 or even 100.000 points would be appreciated...! Today this number doesn't seems to be adjustable and I miss that.

Best regards
Bjarke / call.: OZ2BKK

Very useful instrument for the RF enthusiast

For 4" NanoVNA V2 Plus4

The first version of the Nano VNA was already a cheap incredible instrument.

The version 2, and especially the NanoVNA V2 plus that I received is a huge improvement of the first version, due to the Hardware and the Firmware:
- the RF source covers now a frequency range up to 4.4 GHz
- the display (for use outdoor without a PC) is icreased to 4 inches, providing a useful screen for measurement.
- the firmware allows a full SOLT calibration. The calibration parameters may be saved and recovered on the device.
- the provided reference short, open, and load seems good for the frequency range of the device.
- the dynamic range of about -70 dB (at least up to 3, 3.5 GHz is OK for most of the measurements donee by the hobbyist.
- the small buttons to move the cursors are much better than the command implemented in the version 1.

I regretted however some minor points that may be corrected:
- the device is supplied without a battery. I put in a 3.7V 18650 battery. This works well. The red LED indicating the charging of the battery are however too discreet.
- the ports 1 and 2 are not indicated by some marking on the box.
- the device is really usable with some accuracy, up to 3.4 GHz. Above there is some degradation in the noise, and probably the phase of the receivers.

Finally I recommend this instrument, for amateur use, for RF enthusiasts and surely for teaching.

Happy customer

For 4" NanoVNA V2 Plus4

Hello,

The shipping time was 7 days to Austria.
The needed battery I ordered locally in advance. Power supply I had in my junk box.
After inserting the battery and connecting the USB power the unit turned on as it should.
I am an experienced user of WNVAs and tested the unit to its specifications, there where no discrepancies.
On the internet you can find enough docs and SW, so far I have not updated the FW but I have joined the nanovna group.

This is a product under development and once in a while you should update your FW to get access to more functions.
If you are using it with a laptop I recommend the SW from Joe Smith https://www.youtube.com/watch?v=XaYBpPCo1qk
This SW is not for beginners so get used with your unit stand alone until you know the
All the best from Erich in Austria.

Eugen | April 13, 2021

Great product, works flawlessly

For 4" NanoVNA V2 Plus4

Shippment (with TNT) was very fast (given the distance, communication was friendly and competent, pricing for the product is great.
This product is well documented and open source.

Igor | March 1, 2021

Small yet very powerful device for antenna measurements

For NanoVNA V2 Plus4

Really nice device, have a bunch of features (much more than I can use) and have good precision when compared to another very expensive devices for the same purpose.
Using the PC in conjunction of NanoVNA you can easily fine tune any antenna ou discovery in which frequencies an antenna performs better.
Very useful for any maker, ham radio and electronic hobbyists in general.
In another words, this device is a truly swiss army knife to deal with all your antenna needs ! :D

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

Ken | Jan. 18, 2021

Amazing !

For NanoVNA V2 Plus4

A triumph of technology. I've used it to test a few antennas and will use it to tune filters and matching networks.

William | Jan. 7, 2021

Works great! Could use some labeling

For 4" NanoVNA V2 Plus4

Once I figured out that I had to do a calibration for each frequency setup and could save the setup after calibration it was easy to figure out. I am amazed at how accurate it works. Also the transformation to TDR to measure cable lengths among other parameters was great! Afterwards I found and read the manual -- really helped. I am very familiar with the HP 8753 family, and the performance of the NanoVNA V2Plus4 is comparable. For the price it cannot be beat.

Initially I was put off by the total lack of labeling, but I figured it out and created my own labels.

Greg | Jan. 6, 2021

Good

For 4" NanoVNA V2 Plus4

Received this a while back. There was a small dent in the back lower part of the case just below the USB port that doesn't show or affect the operation of the unit. I'm still learning about this vna and having a little trouble. Not sure but I think the documentation is the same as for the VNA +2. I guess this is a fairly new unit so maybe that is why not much is mentioned about it in the reviews. So far so good though. No functional problems. Ordered an internal battery and waiting for that.

Sachio | Jan. 1, 2021

I can confidently recommend it to those who want to buy it.

For 4" NanoVNA V2 Plus4

I am very grateful that I was able to purchase the high performance NanoVNA-V2-Plus4 at a low price.
As for the support, I recommend that you look at the bulletin board first, because most of the troubles can be dealt with by reading past threads on the bulletin board. Sometimes we get direct advice from developers. In addition, ongoing improvements to firmware could add new features for free. However, VNA is a measuring instrument for professionals, and it is difficult to even begin using it without a minimum of digital literacy. For example, if you don't know about the calibration of the touch panel, you will be mistaken that the VNA is broken and make a stupid complaint. This VNA is properly designed based on advanced high-frequency theory and state-of-the-art digital technology. I can confidently recommend it to those who want to buy it.

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.
