If there is a mismatch at the amplifier, then keeping the
interconnecting cable short, example less than 0.1 wavelength, then the
impact of any impedance transformation in the transmission line is not
so severe. It is best to adjust the tuning on the input circuits of the
amplifier to achieve a VSWR of 1:1 !!
At my station the coax is less than 3 feet between exciter and my
amplifier, AL80B.
