use ladder line to continue on into the tuner?

Some people use side-by-side runs of coax from the tuner
to the outside of the house. The center conductors of the
two runs of coax are used for the parallel lines. The
braids of the coax runs are tied together and grounded.
That alleviates any exposure to bare parallel wires.

Parallel side-by-side runs of 50 ohm coax have a Z0
of 100 ohms. Z0=150 ohms for side-by-side runs
of 75 ohm coax. For low power, side-by-side runs of
RG-62 has a Z0 of 186 ohms.
