How to Read the Smith Chart on the Nano VNA

When tuning antennas for a specific band, we often resort to using a SWR bridge and transmitting on several frequencies to find our resonant point. The Nano VNA gets around this by sweeping across the band at very low power and displaying both VSWR and impedance (using the Smith Chart display).
This video explains how the Smith Chart provides this information, saving you time in determining how to trim your antenna.
