In addition, I can think of no reason that…

    (Or Stuff that Every Ham Should Know) by Mike Jahrig KG5P – KG5P@arrl.net I had a discussion with a fellow ham recently. He has a nice modern rig but was unclear why the antenna impedance and feedline characteristic impedance must be matched to the transmitter impedance (almost always 50 ohms) Since this is something that every ham should or must know, I believe it is important that I mention it. My fellow ham thought that…
