Yes, sometimes but not always. Reflected waves can
actually cool down the transmitter by reducing the
total current.

... and I think I see an example of the "astute choice" illustrated by the
"ladder-line length selector for our all-band dipole" on your website. I
get that and I like it but it would never have occurred to me -- probably
because of lack of wave theory on my part. Am I right?

Probably because of lack of Smith Chart experience?
