I have a SGC-230 tuner in the RV ... I was thinking of adding
ferrites to the input side of the tuner and then using it to tune a
dipole fed with 450 ohm window line.
My SG-230 tuner manual says that is a no-no.
It says: "The coupler must be located *at the antenna*.
Never use a feed line or coaxial cable at the output
of the antenna coupler."
