Connecting the NanoVNA to an Android phone (should work with tablets too)

In this quick video I demonstrate connecting a NanoVNA to a mobile phone (in my case the phone is the Oppo A72 which has a USB type C connector on it and requires OTG is activated manually), the load item I connect is a saltwater dummy load (essentially a glass jar filled with salt water and a SO239 in the lid with copper wire electrodes connected to it), the VNA is able to show the SWR curve of the dummy load and also output it to the phone app. The app is in the Google Play store and should work on any Android phone or tablet that supports USB-OTG #android
