Default sgc dipole?

I expect there's not supposed to be any feedline between the antenna
and the tuner in this installation, so I think that it probably is to
moderate the impedance for a ham band antenna cut for the lowest band.


If I have a different length on the case of the tuner compared to the
length on the hot terminal, how does that moderate impedance?


May be they want the impedance on the second harmonic to be less
*exciting*.

If there is a length of lossy feedline between my resonant 80 m
antenna and the tuner, and I try tuning up on 40 m, I won't fry my
tuner. But if the tuner is at the feedpoint, the voltage gets extremely
high.
