Here is my next iteration (PDF) of a summary of "Antenna Fundamentals and Measurements with a Nano VNA".
I am still learning a lot about this gadget and how to interpret the various graphs.
I've heard you need to do a careful "calibration" to have meaningful results.
I mostly work at HF and mostly on 80m or 20m.
Once you have the fundamentals (new vocabulary) it is rather amazing that a $50 device can tell you so much about
resistance, reactance, impedance, resonance, SWR and phase.
Comments are appreciated as I am going to be giving a talk with SOME of these slides at local radio clubs.
