True, but I have melted plastic insulators on open wire line at about 10
watts when they happened to be right at a high impedance point! Fortunately,
that was at the banana jacks on the back of my ATU where the line
terminated, so I could smell it as well as see it on the SWR meter in the
line to the ATU.

Use the best insulation that you can get at all points. If you can find
them, those old ceramic feed-throughs that were used for "knob and tube"
house wiring years past ought to be excellent for guiding the conductors
through a wall. That's exactly what they were designed for although at 60 Hz
instead of HF. Every time I come across one I pick it up and put it in the
antenna goodie box.
