Re: Are any of the NanoVNA sold on Amazon any better or worse than any others? Is there a better U.S. site to order from?
I'm pretty sure S11 directivity is a well defined parameter. It is the (uncalibrated) ratio between the |S11| reading when measuring an ideal load and the lowest |S11| reading when measuring loads

If you could produce a set of specifications, in a *format* used by Keysight, then people with the right equipment could compare the performance of one NanoVNA-H against and the specifications, and

Re: Cases
OK, I see there is a problem that can be solved quite easily. I have 3D printers and Laser cutters, so if you can give me till the New Year, I will work with you all to design and prototype a case

Re: Cases
Searching ebay.co.uk has the same issue, no cases just nanovna units themselves. I made my own metal box, so not an issue for me. Maybe the vendors have placed a .com or regional listing condition on

Hi to all , I've solved the problem . The instrument-control pakage was installed. The mistake is that I was using the COM14 , that need a different sintax like hCom = nanoOpen("\\\\.\\COM14") instead
