Review: A fabulous, if complex device. - This little machine is fantastic. It does a heck of a LOT of measurements, although typically most purchasers will in all probability only use the SWR function. Pros, This doodabber does a heck of a lot. It is very comprehensive for such a dinky little package. As stated, most will be using the SWR meter function. Which it does admirably. But it also shows Smith charts, and shows a lot more that I don't yet understand fully and yet more I don't understand at all. I'm sure in time all will become clear as mud... So the colloquialism goes. Cons... Do NOT expect a manual! It comes with a list of menu functions. And if your an amateur Amateur radio enthusiast, you will likely NOT understand a single dang thing. I most certainly did not. It has a qr code to a extensive online manual which for the vast majority of the time, is well translated, but can be a little hard to follow (especially for the beginner, YouTube WILL be your friend in this). It NEEDS to be calibrated for every use. Which is a little time consuming. But worthwhile for it's utility. and you absolutely WILL NEED adapters for ANY kind of antenna plug (PL259, N type, BNC, and any other.) It is set up for SMA Type plugs. it comes with what you see which is two extensions cables, both are female to female SMA, A male/male connector and three calibration caps (OPEN, SHORT and LOAD, DO NOT LOSE THESE! they are required for calibration!) A few usb cables (C type for charging and a C to C cable). And finally a wee lil stylus and a 'guitar pick' style doodabber. These are obviously for screen interaction. Build quality: it's a sensitive lil gadget. lightweight, and a little 'plasticky'. But it's well enough made to do what it's intended to do and be robust enough. Although a degree of care should be taken when transporting it. I keep mine in it's box which has sufficed adequately thus far until I get a better option, perhaps a small pelican case. Overall: This gadget does what you will need it to do (meshtastic users, I'm looking at you!) And significantly more besides. I can certainly promise at least 75% of end user's will not utlilise its entire arsenal of tricks. It's compact and very portable. And frankly I'm a little smitten with it. One cannot help but adore a well created and executed piece of kit. especially one as delightfully complicated as this one. 10/10 will measure SWR again.
Review: Good for checking antenna - Works great I use it mainly for checking SWR. Plenty of Youtube videos online to show you how it works.

## Features

- New Upgraded Version: Compared with old version NanoVNA, it save more costs with the addition of ABS casing and the new packaging. Hot stamping technology and plastic inner protection reduce the problems caused by transportation shocks and other processes. Support time domain analysis function (TDR).
- USB-C to USB-C: Support USB-C to USB-C line, more convenient to connect to mobile phones. Compatible with most Android phones with the same screen display (doesnt support for iPhone). Solve the problem of small screen, insufficient brightness and so on. Besides, the battery usage can be displayed on the interface.
- Wide Range Frequency: The improved frequency algorithm can use the odd harmonic extension of si5351 to support the measurement frequency up to 1.5GHz. The metal shield is designed to reduce the external interference and improve the measurement accuracy. The 50K-300MHz frequency range of the si5351 direct output provides better than 70dB dynamic, The extended 300M-900MHz band provides better than 60dB of dynamics, and the 900M-1.5GHz band is better than 40dB of dynamics
- Requirements accomplished by leveraging Spectra Premiums OE engine management systems design expertise.Platinum connector threads reduce the number of connection points for faster reaction to change. Ceramic-built printed circuit boards are protected by silica gel, providing superior resistance to temperature changes and vehicle vibrations.
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

## Questions & Answers

**Q: What does it mean ”if you need to get s12/s22 curve, please exchange the tx/rx port manually”?  is it easy to do?**
A: To change the TX/RX port simply unscrew the connection cable from the upper port on the NanoVNA and reconnect it to the lower port.

**Q: Will the unit be the 3.4 if i order it now?**
A: Yes, it is 3.4 version, if you order it now

**Q: I read in description "900 mhz - enable extended firmware." what does this mean? does it cost extra?**
A: As I understand it, you can extend the range of the device by a firmware update. But there is a resulting decrease in performance. It’s a free update if you so choose.

**Q: What connection type does the battery charger use?**
A: This is an add-on to the other answers that may prevent damage.
Quote from specs. on this product page:  "maximum charging current 0.8A"
In other words, this may get damaged if more than a 1 amp USB charger is used.

### ⭐⭐⭐⭐⭐ Excellent for evaluating antenna
*by T***P on 21 December 2023*

As an amateur radio hobbyist, I was amazed at how good this is for the money. Used it to check SWR and Smithfield on all my antennas, even identified a Chinese knock-off antenna that was useless. Also using it to test filters now. Works brilliantly
