I guess I bought one with the same thinking in mind as when I was about 5
years old and saw kids in the adjacent secondary school making basic
circuits with bulbs and switches in the yard. I never even considered the
fact that one day I would be able to have a decent test meter, a scope
(which I only have basic knowledge of) AND a VNA. It is a new tool for me
and I think that using one after having learned how to use it properly will
help me along the way learning more about radio. I am in my mid 50's now
and am still trying to gain knowledge.

Ok. As long as you know that vector network analysis involves fairly
advanced electronics and mathematics. Good idea to to grips with your scope

Trygve,
Pretty much all tools are solutions in search of a problem. At some point all of us need to pull out a voltmeter to check battery voltages or the continuity of a fuse. However; you can go an entire lifetime without ever running across the need for an oscilloscope or VNA. Some of us who are Ham's never get pass just using the nanoVNA as a bargain antenna VSWR analyzer.

Ok. Good luck with your vna.

Trygve, I have made my notes into a "Tips for New Users" write up. You may find it helpful. I have attached it.

Thanks Mike and all other comments noted. Re: tools, I have the opportunity to learn more about radio antennas with this new tool. I have managed to calibrate it and have taken swr readings but wish to do more than that and learn in the process.

I'm a newbie too, can I get a copy. Thanks in advance. Doug, KI6DS

Did we by chance read the fine print..
For remote regions, we will charge your extra shipping costs. Usually it cost about 35USD-50USD. We will contact you after your payment. Thanks for your understanding.
It will be interesting to see just how remote you are. Not to mention the part about Duties and Taxes.
I am interested to hear how this works out. I am too much of a skeptic to hope to get something
at less than half the going price. Usually doesn't work out for me.

That's exactly the reason to get one. At $50-ish, the NanoVNA is far more than a piece of test gear - it's a learning tool. He'll learn more by having and using it than he will by reading and YouTubing about VNAs.

Mike WY6K I looked at the document quickly. One thing that struck me is the recommendation to add SMA *female-female *adapters so one does damage the connectors on the NanoVNA by rotating them.

Mike thanks for your Tips for new Users doc.
Small comment: I think you mean to recommend a male to female sma adapter and not a female to female sma adapter, since the connection on the NanaVNA is female, you plug the male end of the male to female adapter into the female socket, and then the other end of the adapter presents to right gender - female -- to plug in the cal standards or the device under test etc.

One can never have too many different adapters ?

No, I meant female - because I always use a short piece of coax (male on both ends, like the ones provided with the NanoVNA) on the CH0 port.? However, your comment makes me realize that not everyone will always want to do that.? So I should clarify that point.??

Hi bammi,
I really meant female to female because I always use a short piece of coax (which has male connectors on both ends - like the ones included with the unit) on the CH0 port.? This is the way I have always used VNAs.? But your comment makes me realize that not everyone will always want to do it that way.? So I should clarify the point.??
The important point is to install an adapter on each calibration standard and never remove it.? The calibration standards are male, so whatever you use must have a male connector to mate with it - let's call that the "outside junction".? That connection should remain fixed forevermore.? The other end of the adapter (let's call that the "inside junction") can be male or female based on whether or not you are going to be using a length of coax between the VNA and the DUT.? Make that "inside junction" female if you plan to attach the calibration standard directly (without any coax inside the calibration plane).? Make the "inside junction" male if you plan to use a coax jumper with male connectors on the ends (which is the most common jumper configuration) to move the calibration plane away from the VNA.? The DUT will, or course, always be attached at the calibration plane.
I'll try to clarify this in my notes.? Maybe a picture or two...
Thanks,Mike WY6K

No No Roy! You need the female to female adapters if you use a coax jumper to move the calibration plane away from the VNA and to protect the connector on the VNA from physical stress. Attaching a DUT directly to the VNA connector puts the VNA connector at some risk. My standard procedure is to attach a coax jumper - rather than the DUT - to the VNA, otherwise you wind up with some rather large rigid object sticking out in the air, just asking for trouble. That is such standard procedure for me that using it any other way didn't occur to me. That is what I recommend, but I realize not everyone will always want to use it that way.
Whatever adapter you attach to the calibration standards must have a female connection on that end since the calibration standard is male. The other end should also be female if you use a coax jumper (almost all of which have male connectors on both ends - including the ones included with the NanoVNA). If you do not intend to use a coax jumper, then the other side of the adapter should be male. I just didn't think to point out this possibility in my notes.
I shall attempt to clarify that.
Thanks,
Mike WY6K
