When a VNA is connected to an antenna (often they are outdoors) there are some potential issues with electrostatic discharge (ESD.) In dry areas of the world ESD can be an issue even when working with objects that are purely indoors. I have seen issues when working on tables indoors. Other VNA devices are known to have issues. Does anyone know how sensitive the RF inputs to the nanovna are with regard to ESD? Is there any ESD protection built into the RF connections on the nanovna?
