300 ohm twinlead will give you the perfect chance to resurrect another 1950s practice: aluminum foil wrapped around the line and sliding back and forth to tune/detune any mismatch. Of course, you cannot get the fine feedback with digital that you could with analog.

I was so happy when they got rid of that stuff. Prone to picking up local motor interference, and needed to be spaced away from metallic antenna support structure. The town house I moved to in 1974 had a pre-installed VHF folded dipole in the attic, with twinlead of course, to a living room antenna outlet. Couldn't understand why it was SO lousy until I traced the twin lead and found it was routed through the wall by wrapping it around a convenient electrical conduit.
