> then re-wire it. I sure would. To a reversible "L" for use with coax lines -- or a balanced version of the L for open lines.
With the classic C-L-C "T" design, multiple panel control settings can create an illusion of a low-loss transformation (unless output C is always maximized for the given load). The T is capable of reasonably low loss when the L and C components have a Q > 200 and the output C has > 3000-5000 pF of maximum capacitance where the connection point to the line is under 25-ohms. Myself, I cannot imagine using common wire antennas where the feedline Z at any point on the transmission line is less than 50-ohms. That almost always indicates an electrically short and inefficient antenna unless extraordinary measures are taken at the tuner and antenna to minimize system loss. Most off-the-shelf T tuners suffer great losses with low operating Z. Unless its for mobile use, I really do not want to use antennas that are much less than a physical 1/2-wave at the lowest operating frequency.
