Hi Erik
May I add the short should have a pin sitting directly onto a shorting disk which mates with the calibration plane
Kind regards
Kurt

Emne: Re: [nanovna-users] What options should I look for?

The dummy guide to buying a nanoVNA:

This is the shop of the person that started all this and he delivers good product in excellent packaging.


But if you want to go cheaper these are your options:
Getting the calibration loads is good.
Look for those where the "open" has a hole where the "short" has a pin The cables are also nice as they allow you to have an identical test configuration as many people in this group.
Testing has shown the shielding does not realy make a difference.
Battery is very useful for testing antennas on places where you do not dare to bring a computer.
For the rest, one it arrives, test it and if you are not able to calibrate, request a refund.
