1) use the NanoVNA to sweep and find out where 1/4 wavelength is (i.e. peak in S11 magnitude). Knowing the frequency where it's 1/4 wavelength, you can compare to free space wavelength. 2) Use the

Mike, W2AEW has an excellent series of videos on how to use the NanoVNA to measure and adjust antennas. I think you will find this one worth

If you can't see the NanoVNA-H as a COM port in Windows 11 after plugging it in that means that the driver is not installed. Windows 11 should install it automatically but sometimes it fails to

Very good point about actual VF vs published VF. There are several ways to quickly get the actual VF of the cable using a NanoVNA but the OP ("Anne") doesn't like posts that go beyond specifically

Roy J. Tellason, Sr It looks as "this TDR" subject has life of its own,,, The Agilent article will take me some time to digest... At present I am trying to "run the source code of nanoVNASaver" in

Some intersting reading, there. -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be

Sorry, it was the USB-cable. Should have used the one included. -Oddleiv s?n. 11. juni 2023 kl. 14:33 skrev Oddleiv Tungland <oddleiv@...>:

Ok now, is there a easy way to figure out the resonance of the antenna? I'm useing a different whip and ground plane so the factory (height) on the coil is going to be off so I'm wondering if there is

Hello all, I have a NanoVNA-H wich used to work under W10 with Nanosaver app. After upgrade to W11, when I connect the NanoVNA to usb port nothing happens, no new com port is seen under device

Sorry, didn't read your post correctly. Make sure you save the calibration, Then look on the left of the display to make sure you recall the saved calibration.

Far right is very high resistance, far left is very low resistance. Your open calibration looks good!

Joe, Very good point about actual VF vs published VF. There are several ways to quickly get the actual VF of the cable using a NanoVNA but the OP ("Anne") doesn't like posts that go beyond

Now something to remember, The VF can be FAR from that spec. I have seen Brand New cables that were different THAN THE SPECIFIED VALUE. And as cables age, and it seems this stuff is OLD, that it

Yes, well, the point was to have the OP go the last mile to get the information by following the archive link and maybe learn a thing or two in the process. This probably comes from having a mother

Ok got the Smith chart working in conjunction with SWR reading on port one and verified my calibration (honestly it was a fluke and not sure how I did it lol) So got that issue solved this new

Use the Smith Chart display and make sure that the trace is set to S11 And you (very confusingly) need to connect to and calibrate port 0 for S11 measurements. Port 1 (normally 2) is the return

Although we occasionally talk about other products with the NanoVNA name, this group is primarily about the original NanoVNA design by edy555 and the improvements of it by Hugen (NanoVNA-H and

Use the Smith Chart display and make sure that the trace is set to S11 Roger

Not familiar with setup, but the nano is "embedded " is some other hardware. Can you actually see / observe the nano LED 's? I believe one is a power / battery indicator and the other monitors the
