Good video. Thanks. Question … on p 9-29 of the manual it states “Remember that the impedance matching unit at the transmitter does not reduce the SWR in the feed line to the antenna.” I assume the “impedance matching unit at the transmitter” refers to the antenna tuner (correct?). Please explain the book’s assertion and what the antenna tuner is actually doing. If this is in another video that I haven’t yet watched, please forgive my impatience and point me to the proper video. Many thanks.
