I was doing some modeling using SimSmith and measured values of the shack end of my 450-foot long doublet fed with (mostly) 450-ohm window line. I was not getting what I would expect, so I measured th

It is quite a feat to get a relative epsilon less than 1 <grin> You can do it with ionized plasmas, but I suspect that's not what you have. I'd guess window line, which is 90% "open space" would have

I am preparing for portable operations once the weather gets warmer. I want to take along a nanovna to troubleshoot issues on the field. One important requirement is the scrolling and input control ha

I thought it might be interesting to start a post dealing with how to accurately measure components like inductors, capacitors and resistors on a NanoVNA. As an RF engineer I have made mistakes over t

Ok, after a couple of months on the shelve my 2.8inch NanoVNA-H Hardware version is bricked (I think!). From my reading online, it sounds to be common, I just hope newer firmware will prevent this? I

Here is my latest rendition of the pdf file: Nano VNA: An Antenna Stethoscope After giving a few Zoom club talks on the Nano VNA, I've changed my approach a bit. This is still a very basic look at how

I took the 5-stack 31 material apart (the third entry in the table) and wound a 2-stack 31 material using solid AWG #`12 enameled copper wire. The result is much less loss. Maybe I should have wound a

Hi, new user so thanks for your patience. Calibrated and confirmed appropriate procedure per reference videos. Did a wide sweep, and then resonant sweeps for two different triband antennas and found:

It has been suggested that I update my NanoVNA-h device but as I am not used to updating any software, I need step by step instructions, with no steps missing. In otherwords evert click or data entry

I'm trying to install new firmware using DfuSeDemo. When I start up NanoVNA in DFU mode (with the white screen), and then connect the device to a USB port, Device Manager shows a new Directory is adde

Dear All, I want to use NanoVNASaver for continuously reading and storing S1.p data i.e. automating my experiments for long duration tests (few hours). Since there is no LabVIEW tool available for Nan

I’m having exactly the same problem and this only started following the latest update V 1.0.45

Can the menu buttons/text be made larger? My eyes are getting old :-) The TinySA's menu system is much larger and easier to see. Thanks!

I have a NanoVNA and an H4 model with the DiSlord 1/0/45 version, build Dec 15 2020. I am starting to lad configurations into the various recall groups. I have the same issue with both units. - Enter

Hello, I recently have problems to display Marker 1, Marker 2, Marker 3 and so on . The graphs are shown but I miss the Marker 1, Marker 2, Marker 3 . values (see yellow colour) Anybody out there who

Is there a capability to control the tone used in the sweep or CW? Iv been using it as a tone generator, but I'd like to be able to control the tone freq and level. Thanks a ton, John

A VNWA like Testboard kit is being sold as an accessory for the NanoVNA on AliExpress for $10.00 usd (currently offering 5% discount). Assembly is required so some basic soldering skills are needed. h

I was sent this image today, which is allegedly a new V2 clone on the market with inferior performance. You can see that way under 900MHz the dynamic range has already worsened to 40dB. Currently the

Hi all! I don't know if I have problem, a faulty display or a firmware bug. I'm testing the function L/C Match. I enable the function by clicking "MARKER/SMITH VALUE/L/C MATCH" in the menu system, but
