Beware of cheap underperforming clones

As of 2022 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.

Antenna analyzer function

A kind request to the developers of the firmware ... in the next versions, it would be very nice if we had on the screen the representation of the complex number that represents the complex impedance of the antenna (Z = R + jX) ... this would help antenna developers a lot... Excellent job guys!

We have this in the tiny nanoVNA version 1:

I have not seen the impedance under CH0 SWR.  What firmware for tiny nanoVNA version 1 are you using?

You can select SMITH trace, and in MARKER->SMITH VALUE select format (include R+JjX, R+L/C, Re + Im as so on)

This must be in the later versions of -H or -H4 firmware.  Is it in your firmware, Hugen's or edy555?
