How to use the NanoVNA to sweep / measure an antenna system’s SWR and optimize its tuning

{sizes=”(max-width: 400px) 100vw, 400px” srcset=”https://qrznow.com/wp-content/uploads/2020/06/pic09-e1579354143333.jpg 400w, https://qrznow.com/wp-content/uploads/2020/06/pic09-e1579354143333-300x179.jpg 300w”}

This video briefly shows how to setup and use the NanoVNA to sweep an antenna system (antenna, transmission line, transmatch, etc.) to measure its VSWR, Reflection Coefficient, etc., and then shows how you can use it to monitor the tuning behavior as you make adjustments. The basic steps include: – Setting the traces that you want to display (SWR, Smith, S11) – Setting the frequency range – Running a Calibration – Making the sweep – Using Markers Please see my previous videos on the VNA, Smith Chart, Transmission Lines, Terminations, etc. for more background.
