    RE:  “P.S. I don't subscribe to the notion that quality coax runs of < 150 feetmake it "ok" to have the ATU in the shack while operating an antenna on
multiple bands....what technical evidence of that posit do you have to
share????”

The best source is "Reflections" by Walter Maxwell, W2DU, originally published as a series of articles in QST (difficult to read due to the poor scans) and then published by ARRL as a book.  The latest edition is "Reflections III" published by CQ Communications, but currently sold out.

If you really want to understand what is happening on a transmission line, how an ATU works, etc., then this is the book you should read.  Be warned, though, it is NOT an "easy read", but more of a "great study".  It requires a lot of thought and re-reading to absorb, but is well worth the effort.
