Hugen, Looking forward to this version. When do you think it will be available? I'm trying to keep track of each version. Mike N2MS

============================================================== Given hugen's history on this forum, he generally doesn't start making announcements until he feels his final prototype is ready for

If you are interested in doing a detailed analysis you may be interested in how simsmith can help you Here is an excellent video explaining how to do impedance matching analysis including where the

For the moment, I'm just trying to understand what is going on, impedance-wise, with my antenna system. Not that I am having "problems" that need to be "solved," just curious. When operating, I will

Practical measurement using a 1:1 balun, connected the nanoVNA to one side, other side to the ladder line of a half size G5RV. The ladder line does the impedance transformation to the dipole of the

When using a 1:9 transformer you should connect the nanoVNA to the "1" side and the ladder line to the "9" side. For calibration use a 450 ohm resistor (or a 470 ohm with a second resistor to make it

W5DXP, thanks again, good information. With regard to your previous post, and calibration at the "measurement plane." II understand correctly, this means conducting the SOLT calibration procedure with

Silly me!! I was not paying attention to “PCB”... I was fixated on “version”... Thanks for the info! -- Regards, Chris

So how long off before this new unit is available for purchase? Weeks, Months, a year, years? -- Regards, Chris

Concerning ideal TLTs: First sentence above is true. Second sentence is false. A Transmission Line Transformer has an electrical length. If the load on the 9:1 TLT-balun is not the designed-for load

W5DXP, thanks for your response...I think... What I mean is that you have provided me with another thing to learn about, that is how to "calibrate your measurement plane at ..." Do you have any

Hi Herb, I’m also new to this, and ordered a NanoVNA which is arriving today. Is it not possible to update the bios/software on these units? I assumed they can be and didn’t even consider the

I've done it. Simply calibrate your measurement plane at the output of the balun that feeds the ladder line. The attached graph was done with an AIM-4170D but the calibration procedure for it and the

Erik, if I understand correctly, the purpose of the 1:9 balun is to reduce impedance by a factor of 9. So, presuming that I have a 450 ohm load at the end of the ladder line (which might not

Hi Helmut, Nick, Corneliu and Martin, thanks for the kind replies - indicating that the Lambda/8 method is not commonly known. The value measured that way is good for just that one Lambda/8 frequency.
