At the regular SVARC club Zoom meeting on Thursday, September 17, 2020, at 7:30 pm, club member Roger Steyaert K7RXV made a presentation on the topic of network analyzers. These can be used to measure antenna or coax parameters such as SWR, impedance, and loss. They can also be used to characterize and tune filters. A network analyzer is a very useful tool to have if you are building and tuning homemade antennas, filters, or other RF circuits.
