Antenna test jig AKA bulletproofing your nanoVNA

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 test jig AKA bulletproofing your nanoVNA

Sorry for the size...

Designed primarily to test antennas and protect SMA connectors and to recycle "stuff"...
The unused connector , not yet wired, plus the 3 way switch ( short open load ) - to simplify "calibration "
The "T" and adapters holds both - the antenna coax plus nanoVNA connection...

PS Minor impedance mismatches are irrelevant - for me..
