Hi,
I am a newbie here and on nanoVNA
Any online sources for how to use, without too much technicality, for antenna z, resonance, lc resonance and L inductance. Not interested in Smiths

There are a three books you might like to look at:





Smith charts can be helpful to show resonance, cable lengths (e.g. 90 degree
phase shift) etc., and will likely be explained in the books I mentioned.

Maybe it's better to say what you want in stead off your non-interested. I personally use it for that, what are your intensions.

Hello

nanoVNA without technicality seems unnatural to me. It is a measuring device; you must therefore master what it measures, otherwise it will not be too useful to you.

The current use of the Smith has nothing to do with the use for which it was designed and used. Before, we used the Smith, at a fixed frequency, to calculate graphically. Now we use the Smith to represent, in a frequency band, an impedance. With computers, there is no point in making calculations graphically: it is long and imprecise.

You will notice that the Smith that appears on the nanoVNA is not scaled and the graph you see is a trace because the frequency is swept.

If not interested in Smith Chart,

touch the nanoVNA's display, then choose trace, switch off the Smith trace.
