Smith 4.1

Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

For anyone interested in using their NanoVNA for matching, here is a great
resource for a nice (and free) Smith chart program. I have been using it for
over 25 years, and it helped a lot with circuit matching.

It has gotten a lot better over the years
