WebAn acoustic transmission line is the use of a long duct, which acts as an acoustic waveguide and is used to produce or transmit sound in an undistorted manner. Technically it is the acoustic analog of the electrical transmission line, typically conceived as a rigid-walled duct or tube, that is long and thin relative to the wavelength of sound ... http://arrl.org/feed-lines

Web$\begingroup$ @Andrew My point is if the tuner does need readjustment, then the tuner isn't compensating for the impedance of the antenna, because that doesn't change as the feedline changes length. Rather, it's compensating for the impedance of the antenna as transformed by the transmission line, which does change. Also consider that 25+0j ...
