Antenna Tuners: Impedance and Feedline SWR - Two Experiments (076a)

********* NOTE: I make some comments herein about where the reflected power ends up. These are going to be refactored in the next video where I address the issue more directly. ********* Antenna Tuners or Antenna Matching Networks ... they are ubiquitous in the Amateur Radio World. They used to be things that hams either built for themselves or bought as a separate unit to include in the shack. Now they are very often included in transceivers. This video is an adjunct to the previous two videos that I created on the subject of antenna tuners. In this video I will perform two experiments to demonstrate two aspects of what they do. These are related to specific aspects of what they do after they are fully tuned to provide the lowest SWR for the transmitter: 1. Impedance at the Antenna connection 2. Feedline SWR. The next video will address the topic of the reflected power in the feedline and its associated SWR. ======================================= Time Markers for Your Convenience ---------------------------- 00:05 Introductory Comments 01:35 Experiment #1-Impedance 01:35 Introduction and Setup 02:16 Performing the Experiment 05:11 Experiment #2: Feedline SWR 05:11 Introduction and Setup 05:57 Performing the Experiment 09:06 Final Comments and Tootle-Oots
