Impressive

For NanoVNA V2 Plus4

I can't think of a better ROI for $80 worth of lab gear. I'd be hard pressed to think of anything I've bought in the past 3 years that provided similar value without costing thousands. After unboxing it, I downloaded the Linux software and was tuning an LTE chip antenna in no time flat. Validated S11 measurements against the RF lab's and they were spot on.

I then proceeded to fine tune the antenna for a project that will show up here on tindie at some point and that was eye opening to say the least. Since then, I've used it to validate, tune and even reject different bandpass filters and matching networks as well as entire gain stages. S21 measurements seem accurate.

If you've been thinking about getting a VNA and you don't have a $3k+ budget, this is it!

Must buy

For NanoVNA V2 Plus4

If you use/design any RF products buy it: This is a true, 4GHz, 2-port VNA.
PC Software is easier to use than the LCD in my view, as this is a tad small.
Finding a LiPo battery that fits inside with 2.54mm JST is not easy. Shame its not a purchase option.

Exactly as desired!

For NanoVNA V2 Plus4

Very affordable and useful to have around. Appreciate the included standards (short, open and 50 ohm load) as I didn't have any of this equipment previously.

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.

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.

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.

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

Отличный продукт!

For NanoVNA V2 Plus4

Отличный продукт, дошёл без проблем в Россию. В комплект продавец положил калибровки и провода. Модель корпуса нашел в интернете и напечатал.

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.

Michael | June 18, 2020

Great Product

For NanoVNA V2 Plus4

Received mine today in Australia 8 days after purchase.

Very happy so far but still lots to learn.

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.

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!

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!

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.

Dokumentation gibts nur im Internet

For NanoVNA V2 Plus4

Was lange währt wird gut.Nach 7 Wochen angekommen und es funktioniert alles. Tracking könnte besser sein.

Wouter | April 27, 2020

Great product.

For NanoVNA V2 Plus4

I ordered the VNA + SOLT + cable set on April 6th and it arrived 24th April. That is within 3 weeks even during these troublesome times. Nice.
The product it self is amazing, just the amount of features is staggering. The device takes a little time to get used to, being small as it is. I tested a 2.4GHz filter and a 7MHz antenna, both showed the expected results. Very happy with my VNA!
I installed a Li ion battery and it worked first time!
Would recommend it to everyone.

John | April 24, 2020

Excellent performance at a bargain price

For NanoVNA V2 Plus4

The NanoVNA-V2 took a while to arrive with the COVID-19 delays, but it really performs. It easily meets is specifications. I have compared it with much more expensive equipment like the HP 8753D, and it gives similar results. If you need to work on RF networks up to 3+ GHz, there is presently nothing that comes anywhere near the NanoVNA-V2 performance/price ratio.

Ronchi | April 10, 2020

Very, very good

For NanoVNA V2 Plus4

Fantastic little vna, with accuracy similar to that of professional instrumentation: no more than one or two tenths of a dB with respect to HP 8753A on gain measurements to 3 GHz!
For this price really no more to ask !
