NanoVNA V2 Enclosure and Carry Case Now Available on our Store with Release Discount

We have just release for sale our latest product which is an enclosure and carry case for the NanoVNA V2. It is currently on sale until the end of this week for US$14.95 including free shipping from China to most countries. At the end of the sale the price will rise to US$19.95. Amazon will be stocked in 2-4 weeks, but will not be on sale. Please visit our store at:

The enclosure is made from rugged plastic (plastic was chosen as the NanoVNA designers note that a metal case may actually degrade performance). There is space included for a standard sized (non-protected) 18650 battery, and battery terminals are included for optional use (battery not included). The enclosure also has a holder for the NanoVNA V2's stylus, and as a bonus we're including a matte antiglare screen protector as we found the NanoVNA V2's screen to be quite reflective. Finally, a protective semi-hardshell carry case is also included in the set. If you are installing a battery, please consult the installation instructions PDF file.

 

NanoVNA V2+ Now Available in our Store + Upcoming Enclosure Preview

The original NanoVNA V2+ is now available in our store for a reduced price of US$64.95 with free shipping to most countries. This price will increase in the future. The NanoVNA V2+ is a low cost vector network analyzer which can be used to measure and tune antennas, filters and cables.

The model on our store is the ORIGINAL product manufactured and designed by HCQXS + OwOcomm, not a clone. So purchases from our store support the developer. It is also the newer 2.8" V2 PLUS version, which has a two times faster sweep speed compared to the older model. The price includes the calibration kit which consists of two high quality SS405 cables and a SOLT (short, open, load, through) kit. Note that in our current stock we do not include the optional acrylic case.

NanoVNA V2+ Kit

However, we do have our own third party enclosure for the NanoVNA V2 that will be released by January next year. Our enclosure will be made of rugged plastic, and will be part of a kit including an antiglare screen protector as well as a carry case. The case includes space for a standard sized (non-protected) 18650 Li-Ion battery, and will include battery terminals (the battery itself will not be included for shipping reasons, but you can find 18650 cells for a few dollars locally). Pricing is yet to be established, but we're targeting around US$14.95 to US$19.95 with free shipping included. We note that some people have requested a metal case, however after a discussion with the NanoVNA V2 designers it was noted that a metal case could actually hurt performance and is not recommended.

Andreas Spiess Shows how to Properly use a NanoVNA V2

Over on his channel popular electronics YouTuber Andrea Spiess has uploaded a tutorial video showing how to properly use a NanoVNA V2. The NanoVNA V2 is a vector network analyzer which can be used to measure and tune things like antennas, filters and cables. In the video Andreas aims to explain the differences between the VNA, Spectrum Analyzer and VSWR meter, what you can measure with a VNA, how to read the VNA results, the limitations of cheap VNAs, why and how to calibrate, and a review of the overall quality.

Andreas explains these concepts in a very easy to understand way, so this video is a great start if you've ordered a NanoVNA.

The NanoVNA V2 (aka S-A-A-2) is a vector network analyzer (VNA) with 50 kHz to 3 GHz frequency range. Recently is has become readily available for around $60 + shipping from the Tindie store. We like this product a lot and are planning to get some for our store soon as well. (Update: A limited quantity of NanoVNA V2's are now available in our store)

A Vector Network Analyzer (VNA) is an extremely useful tool for radio hobbyists as it allows you to measure and tune antennas and filters, as well as measure cable loss among other applications. Until recently low cost VNA's cost hundreds of dollars. Then came along the original NanoVNA which brought expensive VNA capabilities to the masses with its low $40 pricing. But the original design is limited to a maximum frequency of only 900 MHz. The new V2 design pushes this maximum frequency up to 3 GHz officially, and unofficially up to 4.4 GHz with reduced performance. It also improves on overall dynamic range and maintains the affordable sub $100 price. We note that the NanoVNA V2 is unrelated to the original NanoVNA apart from being the inspiration, and sharing the same firmware base.

Over on YouTube Robert J. Meade has been uploading a series of videos demonstrating and teaching viewers how to use the NanoVNA V2 to measure various devices. For example in his videos he shows how to use the NanoVNA V2 to measure one of our RTL-SDR Blog Broadcast FM filters, how to measure a log spiral & clover antenna, use measurements to rebuild a variable attenuator, measure an active device (SAWbird+ NOAA), and how to measure a DIY microstrip L-band LNA. If you're just getting started with the NanoVNA V2, then these are some great videos to start with.

NanoVNA V2 Now Readily Available for $60 + US Stock Available at R&L

The much awaited NanoVNA V2 is now readily available for around $60 + shipping from the Tindie store. Shipping is noted to begin on June 30th due to a public holiday and you must agree to possible pandemic delays, although feedback from earlier customers indicates that most countries appear to be receiving the packages in good time. You can also add a calibration kit for $10 extra, or a calibration kit and acrylic enclosure for $14 extra.

For US customers R&L Electronics have them in stock in "high end" for $59.95 and "low end" for $54.95 options. The high end option appears to have higher quality cables included. UPDATE: It has been brought to our attention that the stock at R&L is actually from a "clone" manufacturer and the clones do not support the original developer.

We note that the NanoVNA V2 is an open source project created by OwOComm, a research organization with a mission to further "intellectual communism". Therefore any factory is free to produce their own version from the designs, and hence several other versions have already been showing up on marketplaces like Aliexpress/eBay. However, for now it is probably safer to buy directly from the original manufacturers on the Tindie store. This is because according to the developer the quality of the "unofficial" clones that are showing up on Aliexpress and eBay is not yet known. The official version also supports the original developer and funds future software development.
