Great Product

For NanoVNA V2 Plus4

The product was received in New Zealand without any delay. I was able to track the shipment by TNT. The communication with the sender was great and the product far surpasses my expectations.
A great asset to every HAM and it won't break the bank.

a nice piece of measuring device

For NanoVNA V2 Plus4

I had only a little problem with the plastic box, the micro switches on VNA V2 were mounted higher than the holes on the box - otherwise it's perfect.

A cheap way of Antenna measurements

For NanoVNA V2 Plus4

I have used this product to measure S11 and Z of helical antenna. I have used measured three antennas with it. Used its PC app for both windows and ubuntu linux. I highly recommend this product for students of Elecyrical engineering.

Very usefull and eazy to start working with

For NanoVNA V2 Plus4

Purchased with full accessory set. The nice thing is that device works right out of the box. Easy to calibrate with supplied standards. The sweep is running continuosly and the screen is updated immediately, so you can adjust your antenna or other RF device and observe the changes. Also the PC software is simple to work with, no installation required, only need CDC UART driver to be installed. The manual describes set of UART commands, so it is possible to implement your own software for some automation.
Keep in mind: sweep from 2000 to 3000 MHz with 10MHz step size has 101 steps. So add one more step to what is suggested by QT GUI.

Great product and smooth purchase experience

For NanoVNA V2 Plus4

Everything went well for me - purchased the full package (nanoVNA2 + case, calibration kit, RF cables). Shipping was done by TNT and I was able to track the package using their app nicely. It was paid for on 1st of August and received the package here in Budapest, Hungary today. The device works as expected and I was surprised about the (lack of) performance of some of my branded antennas.. its trully an "eye-opener" device so to say..

Recommend for every ham radio operator.

For NanoVNA V2 Plus4

After ordering, received the within a week (very fast delivery). Package was damages (skewed) but content luckily was OK. Damage, probably happened during transport, wasn't notable because the box was in a plastic shipping bag when the parcel services handed it over to me.

Owning a NanoVNA V1, I knew what I had to look for. Calibrated the unit and tested a few antennas and filters with my QRP-Labs filter adapter and responses where as expected. Dynamic range is much better then the NanoVNA V1, and now we can measure GSM/GPS/NB-IOT/WIFI and 13/23cm hamradio antennas.

A few minor findings :
- display wasn't nicely fit on the display PCB (glued?) making it hard to use a tight 3D printed case (printed and would recommend https://www.thingiverse.com/thing:4535938 ).
- When the display is flipped, touchscreen calibration doesn't work correctly. Work around : when touchscreen calibration indicating upper left corner, tap in lower right corner. when indicating lower right corner, tap in upper left corner. Reported as a issue in the firmware repository on github.
- there is no display battery indicator, the battery state is now indicated by led on the side. Think I have to get used to it, but liked the indicator in the V1 (especially when its turned red to indicate low level).

Would recommend it to every ham radio operator who want to work up to 3Ghz and maker which is using RF in its projects.

Получил посылку. Состояние упаковки ужасное. Фото сделал но вставить не получается. Коробка вся помята.
Кабеля USB нет в комплекте, гаек нет для крепления к корпусу. Не рекомендую этого продавца.

great bit of kit

For NanoVNA V2 Plus4

I thought all my home made radio antenna worked ok ,but after getting my nanova V2 i realised how poorley tuned they were !! i am currently pulling in ADSB from 200 miles away with a simple 8 leg spider antenna due to it being resonant and matched to coax thanks to my nano V2..c.wilson UK

Incredible tool for the price

For NanoVNA V2 Plus4

I bought the V1 nano VNA a year ago and definitely appreciated the functionality it brought in such a small and portable package, but the frequency range left a little bit to be desired. The improvements brought forward in the V2 are well worth the price. The sellers were excellent with their communications and willingness to combine orders. Shipping was virtually immediate considering the origin. Thanks for such a great product and experience

Jacques | July 17, 2020

Good product, amazing performances.

For NanoVNA V2 Plus4

This small device is a very amazing equipment which can be useful for all hams with a good accuracy.
For the fans, the Smith Chart is also displayed.
Offically the range is 50KHz to 3GHz but it is possible to use it up to 4.4 GHz. For the fun I have done correct measurements between 4 and 4.4GHz.
So it is usable up to the 9cm band.

Floris | July 17, 2020

Great little VNA

For NanoVNA V2 Plus4

Amazing small and capable little VNA.
For this money an incredible attractive analyzer.
Hats off for the designers

Excellent tool

For NanoVNA V2 Plus4

8 days from order to delivery Lucca, in Italy
Ordered without case or calibration kit,good for portable use

Stephen | June 27, 2020

Impressive Tool

For NanoVNA V2 Plus4

5 days from order to delivery in Melbourne, Australia.
Ordered with acrylic case. I made acrylic washers/spacers, od=6.0, id=3.0, h=3.8, to better mount case to boards.
Impressed with accessories.

Jeffrey | June 26, 2020

Great device - shipping took ages

For NanoVNA V2 Plus4

Shipping took ages but ok, COVID had something to do with it. Sweeps reasonably fast. Updated to the latest firmware via NanoVNA-QT. Good that you can flip the screen. Ports on top make more sense to me. Impressed with thermal stability for such a cheap device.

Needs to be improved

For NanoVNA V2 Plus4

Compared with the first version, nanoVNA did not like:
1. Incorrectly measures capacitance and inductance.
2. For each new frequency range, you need to do your calibration. In the first nanoVNA, I did a calibration once, and switch the frequencies as you want - the calibration will work fine.
3. The battery charge indication is made by a line of four LEDs, and not by a symbol on the LCD.
I think that all this can be improved by fixing the firmware.
25.06.2020:
Capacitors 6.19nF + -0.5% and 38.3nF + -0.5%
nanoVNA ver.06.2019: 6.2-6.21nF 38.4nF
nanoVNA ver.11.2019: 6.19-6.2nF 38.5-38.6nF
nanoVNA2: 5.97-6.05nF 42.0-42.1nF (immediately after switching on)
nanoVNA2: 6.15-6.24 nF 42.0-42.1nF (10 minutes after switching on)
nanoVNA2: 6.19-6.30nF 41.9-42.0nF (25 minutes after switching on)
The measurements were carried out at a frequency of 50 kHz. The capacitance of the capacitors, measured by an attorney with an error of 0.3%, was 6.2 nF and 38.3 nF.
When measuring an inductance of 5 μH + -10% at a frequency of 50 kHz, nanoVNA2 shows 2.41-4.77 μH (readings randomly jump) and only at frequencies of 1-2 MHz the readings are normal - 5.4 μH. Your nanoVNA2 is very hot compared to the first version. When I try to determine the heat source by touching the board with my finger, the device failed - on the Smith diagram it shows 5 Ohms with the input open. I touched the details above the lower right screen (CH1). Tell me, what kind of chip could fail?

Can you give an example of incorrect capacitance/inductance measurements? Other users have done accuracy comparisons: http://www.dd1us.de/Downloads/Brief%20comparison%20of%20NanoVNA%20V2%20with%20a%20professional%20VNA%20HP-8753E.pdf

extreme shipping

For NanoVNA V2 Plus4

I have ordered it on Wednesday, it was shipped on Friday and arrived on Monday to German customs which it cleared on the same day.

Sascha | June 15, 2020

Very quick delivery

For NanoVNA V2 Plus4

Ordered on Wednesday, sent Friday and received in Germany on Monday. The functionality of the NanoVNA V2 is as expected.

Richard | June 15, 2020

Wow very nice

For NanoVNA V2 Plus4

Seems to work great! I got with O/S/L cal kit and case. The case is a simple set of laser cut plastic pieces, it's ok but nothing fancy. Device itself very nice, just measured some antennas and a filter and it looks good. PCB has shielded cans for critical parts, is well made. Touchscreen small but perfectly usable (stylus provided), menu system easy to use, no complaints. Desktop software also looks decent. Ordered June 10th, arrived on the 15th to USA. Very happy! Great job.

John | June 8, 2020

A great product

For NanoVNA V2 Plus4

I really like this thing and I'm glad that I was able to get it! It's been super useful for analyzing antennas and tweaking filters. I travel a lot so having something this compact that goes into the gigahertz range is very practical. Great communication from the sellers and the calibration kit is of good quality! I would definitely recommend this product and these sellers!

NanoVNA-2

For NanoVNA V2 Plus4

I have receive your NanoVNA-2.
It is OK.
I would also need the enclosure, but I think it is a little bit expensive with shipping costs
Thanks

Reinier | June 3, 2020

fantastic tool!

For NanoVNA V2 Plus4

I was one of the first to order (2 units) but it got stuck in transport for months. Seller noticed and sent new devices with TNT express service at no extra cost. Now they also included a cal kit, cables and a plastic housing. I'm not impressed with this housing, but I am impressed by the customer service and the device itself.
I did a quick test at 850-950 MHz and it just works fine!. Very low noise, no spikes and s21 peak noise floor is around -75 dB, very acceptable.
Of course, a VNA is a good as your reference. I need to find the right s-parameters of the supplied open, load and short. A load that I trust measured s11=-40dB, so that is excellent for all practical measurements. So far the device surpasses my expectations.
Thanks to all who made this happen!

perfect product for a reasonable price

For NanoVNA V2 Plus4

I ordered NaNoVNA V2 on April 2 and it has arrived until May 15, but it is okay due to the worldwide Covid problem. The shipment arrived safely, but I have only one remark or suggestion concerning the packaging. The paper box with NanoVNA was not sealed with tape or any other way, so anybody during the transport could easily open the box and take the content of it away.

Concerning the product itself, I am very satisfied, I would recommend to offer at least one calibration set to it, as far as this is a necessary tool for that instrument and maybe a SMA saver to protect built-in connectors from the wearing.

Michael | May 30, 2020

Awesome, better than expected

For NanoVNA V2 Plus4

Ordered April 10, shipped the next day but received May 30th, 48 covid days, total. It arrived in good shape.

Seems to work so far. No precise measurements yet as Cal kit was not available when ordered and my Cal kit from another source hasn't arrived. The battery JST connector is reversed polarity from my RC car battery so you might want to check.

Extremely small text but graphics nice and crisp. FYI four metal shields of possible six? Seems rugged enough, high quality, no visible bodge wires or flux or rework residue.

Software on Mac OS worked great(but is not code-signed) and was used to update VNA V2 firmware to latest.

Eugen | May 27, 2020

Product as promised

For NanoVNA V2 Plus4

Product as promised and actually excellent shipping, regarding that all hell broke lose just a few days after I ordered the vna. Also the fact that (actually just one day before the package was delivered) this seller reached out to me, apologizing for long shipment delays given the corona situation, I keep in high regards.

An excellent tool for the VHF-UHF-SHF radio amateur

For NanoVNA V2 Plus4

I ordered NaNoVNA V2 on April 2 and did not arrive until May 20. Covid-19 was a problem. Shipping 6 weeks. The shipment arrived safely.
It is a very nice and successful construction. I did a firmware update without any problems. It will be a good tool for my amateur workshop.

Very nice product

For NanoVNA V2 Plus4

You get very good value for your money on this product. I find the build quality very good. Performance is best when controlled from a PC. Use Nano VNA view as PC SW, which makes it easy for SW update also.

Darius | May 14, 2020

great tool to have

For NanoVNA V2 Plus4

Was looking for affordable tool to buy for my iot projects.
With operational frequency up to 3GHz - great for esp32, bluetooth projects. Being able to match 2.4GHz-2.5GHz antennas with a few minute setup is well worth the investment if you're into this kind of stuff (also might be great for learning basics of rf)
