Dave Casler wraps up his 3-part series on Antenna Systems with this outstanding video. Although the video tutorial is geared for those taking the Amateur Extra Class License Exam, there's plenty of good, basic antenna information in this program series for the rest of us. In this video, Dave discusses impedance matching of transmission lines to antennas, how transmission lines work, The Smith Chart, transmission line stubs, synchronous transformers, and antenna analyzers. This 3-part antenna series should be part of your Amateur Radio library. For the latest Amateur Radio news and events, please check out the blog sidebars. These news feeds are updated daily.
