Try cutting double or single sided FR-4 board to the required shapes. Also, useful thicknesses of small copper sheets are available at Ace Hardware (and likely other outlets). Keep in mind that these

The NanoVNA DOES have a setting to display SWR. It just generates its own signal to measure it; it doesn't connect to a transmitter. The same with the RigExpert AA-600. It generates its own signal to

Any amateur radio operator using a NANOVNA (or even the TinySA) should absolutely know it's a low-power device and not fit for inline or terminating installation!!!!!!! It ain't no Bird

Good afternoon Dave, Do you know whether those copper blanks are available anywhere that can be bought? I have tried making some with not much success. Fred - N4CLA

The NANOVNA can be used directly at 300-ohm resistance. Careful calibrationn and placement of the cursor is required to ultimately read values is required, but can be accomplished without introducing

SMA connectors are for good two reasons: 1) Small size and 2) Frequency response. SMA connectors are bad for one reasonable consideration: Limited service lifetime for mates/demates. Banana

New users of the NanoVNA have many questions about their new piece of test equipment. They will find a lot of useful information and User Guides in the Files section of this group.

Typically, I use a BNC-dual banana jack and a SMA/BNC adapter. I don't know that anyone sells a SMA-Banana I've built them over the years. Usually, by cutting a SMA-SMA cable, splitting the coax and

In general yes. The miniVNA uses a different receiver design, and different ways of sampling the signals, but the basic concept is the same - look at reflected signal vs incident signal. Calibration

You can easily measure impedances up to several thousand ohms using the S11 (CH0 or Port1) shunt method if you have a decent test jig (see group wiki for details). The higher you go the worse the

Yes

Try reading this groups's Wiki to learn more about testing jigs to measure components. Roger

Anyone has or seen an sma male to an open banana binding post to connect to components ?

yes, now go measure with your nano if you have one. What is your name? (second time I ask) Op 20-7-2022 om 16:08 schreef Observer:

I have found the most, mouthful fed examples on how to use a vna. But, can the miniVNA measuring techniques be directly applied to nano ? https://www.nonstopsystems.com/radio/frank_radio_coax-sw.htm

That's another good reason or feature of the Nano's price! If you blow it up (by transmitting into it), it probably won't break the bank. BUT if the transmitter blows up too, well then you'll wish you

I don't think you want to use them together. The NanoVNA directly measures impedance vs frequency. Yes, the usual display is S11 referred to 50 ohms, but you can convert that to R and X (and, in fact,

I don't know that there's published specifications - it's more "we built it, you use it, as found" There's a fair amount of lore - measurements people have made, etc. It's kind of different from

Most interesting, Arie, thanks for posting. Judging by your plots, I'd say the 1-ohm to 470-ohms range is quite acceptable. More complex, though for someone wanting to measure antennas! 73, David
