But I only have one unit, and I would like to know if there is an easy way - ie, without an oscilloscope etc - to measure the transmission loss through a unun.

Probably the best inexpensive technique would be using back-to-back or tandem identical devices. The back-to-back system allows use of 50-ohm meters at each end, or S21 and S12 measurements with

What do you mean by "without another one in tandem"? OE8UWW

MFJ is selling a set and that is good enough for HF and the tolerances are good enough for every day "hobby" work. I always lol at people promoting commercial calibration standards costing hundreds if

Hello team, Is there an easy way to measure balun loss, without another one in tandem S11-S21 ? I only have one and I would like to have its characteristics, including loss. Cheers and thanks in

Thanks to all who had suggestions on this matter. Larry, K4MLA

I got mine from Mirfield Electronics, you could also try Canny Components. Ian

If you want to build your own BNC calibration standard, OZ7OU has some detailed info at http://www.hamcom.dk/VNWA/How%20to%20design%20a%20homemade%20male%20BNC%20calibration%20kit.pdf

Phase measurement on the reference line. At a frequency of 600 MHz, it is very accurate, at a frequency of 1250 MHz a slight discrepancy. For information to the group.

NanoVNA need ~1-2ms for measure 1 point Pause 0.5ms between measure points for wait si5351 freq lock (can be larger on band change)

Did a search on google using "bnc calibration kit" and had several hits that includes both male and female configurations along with a wide range of cost. -- David S

One caveat to measuring at the end of a long cable is that the calibration and measurement may need to have the sweep speed reduced. A round trip reflection cal or measurement with a 100 M

Hello all- received my nanoVNa from Amazon Sunday, have the Saver software running on win10 ok. Trying to also install on Ubuntu 18.04, but run into problems: ~/nanovna-saver$ python3.7 -m pip install

Don't know whereabouts you are. I bought my nanoVNA-H from Mirfield Electronics here in the UK. Arrived in 4 days, well packed and included a couple of extras adapters for PL259/SO239 in the price.

IN France, we have https://www.passion-radio.fr/appareils-mesure-rf/nano-vna-918.html
