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.

Adapter for Nano

Dick Hoelz 2025/08/12 15:54

There have been discussions regarding protection of the Nano from excessive
input signals. I decided to bit-the-bullet and buy a Mini-Circuits Limiter
(VLM-33W-2W-S+) from DigiKey. The price of the limiter was worthwhile
compared to the price of a new Nano.



Another issue is the fragility of the SMA connectors. I decided to build a
frame to hold N connectors. Attached are three photos of the Nano with the
adapters. The frame is attached to the Nano using the existing screws that
hold the cover to the Nano.



The number on the Nano is the software version of the unit.

Consider using SMA connector saver?
