Tomohiro Takahashi (AKA edy555) in Japan kicked this off with his low volume kit
that I believe is no longer available:
Hugen in China is mass producing a completed device with significant improvements
Hugen at first just called it the "nanovna", had the same 2.8" screen as edy555's design.
Hugen changed the name to nanovna-H, made some minor changes to improve
accuracy at 1ghz+ frequencies, and to allow easier comunication over a USB-C cable.
Most of the clones are of the nanovna, or perhaps nanovna-H, have the 2.8" screen.
There are a number of variants being built.
Hugen is building the nanovna-H4 with a 4" screen, has a bigger processor, but other than the screen
is pretty much identical to your nanovna-H.
There is a nanovna-F, also with a 4" screen, being built by somebody else, has significant changes,
but I believe is roughly equivalent to the nanovna-H4.
The SAA-2 designed by OwO and friends is good to 3ghz.
The new V2 that Hugen is working on should do 6ghz.
But for most of us using these things below 1ghz, any of the variants will do.
Regarding the SAA2, Hugen posted a polite reply to OwO in the recent forum thread.
His post was lost along with all others when the thread was terminated.
Hopefully Hugen will make it publicly accessible elsewhere.
R&L distributes Hugen's products here in the USA, I was very happy buying through them.
I bought $60 nanovna-H4 with the 4" screen, they also sell a 2.8" version, and the SAA2.
The tinySA might also be of interest. Arrived in about 3 days.
A good starting place for figuring out how to use a nanovna is the hexandflex tutorial:
Looking through some old posts in the forum, I suspect Aursinc is distributing
product from Hugen (since they shipped a very early nanovna-H4).
Though hard to say, many distributors switch between manufacturers depending on
who has stock, and what's cheapest.
There seem to be dozens of Chinese clone shops building nanovna's now.
Some better than others.

Hello All,
New member here as well as a (soon to be) new owner of a Nano-VNA. I purchased
the Aursinc:
【Upgraded】AURSINC Vector Network Analyzer 10KHz -1.5GHz HF VHF UHF Antenna
Analyzer Measuring S Parameters, Voltage Standing Wave Ratio, Phase, Delay,
Smith Chart(Latest Version REV3.4) <
From our favorite internet site… $69. Plus a couple of adapters.
Like many, I plan on using this to measure built and constructed antennas for
HF. I have watched several youtube videos in anticipation of the device’s
arrival. With this in mind, what files gathered here that should I read to
understand this particular Aursinc device. I understand that this device is
designed in Japan (and built in China). Does anyone know if this is true, if
this device is one of the “originals?”
Thanks in advance,
Roger Need
