    Howdy,

    I really want to to say this as respectfully as possible, but, for some of us (with an EE background) both videos were rather painful..... The concepts you were "experimenting" with (because of the questioning of what could be called accepted and already proved "theory") literally "flew in the face" of P.H. Smith (the inventor of the "Smith Chart")

    He didn't really "invent" the theory, he just came up with a simple very easy to use graphical representation of the actual (already proved) theory. Every Student of Electrical Engineering gets an entry course (plus lab) in electromagnetics that includes some fairly simple proofs.......one of which happens to be shorted and open transmission line stub matching in antenna systems and all the characteristics of those various length sections of transmission lines (twin-lead, coax, and waveguides etc... when terminated, shorted, and open)

    I don't do instructional videos. But if I could offer some constructive criticism, simply changing the the narrative at the beginning of your first video to, for example, "This is an example of an experiment to show what various lengths of transmission line will do if treated like an antenna when open, shorted, or terminated with a varying resistance"....... would have likely eliminated the bulk of the criticism.

    Seriously referring to a shorted (or open for that matter) transmission line as an antenna from the get-go made a LOT of us with EE backgrounds "cringe" ......

    Just saying,

    Also, since I cannot now edit my original post above, anywhere I referred to "you", I of course meant the Author of the Youtube video and NOT and not KB7TBT above!

    Cheers Y'all!

    I'd say "mission accomplished." Well done!

    ...and a few of we mere mortals with only ET certificates, too.
