If passing the line through the wall is the problem then just use a foot or
so of electrical mains "zip cord" for that short passage. Simply solder a
short piece of zip cord into the 450 Ohm window line at the appropriate
place to allow the line to pass through a small 1/4 - 1/2 inch hole in the
wall. The "impedance bump" caused by the short hunk of zip cord will never
be noticed throughout the MF/HF bands.

Yes, the impedance "bump" isn't a problem, but I would be concerned
about voltage breakdown. Most zip-cord is rated at a maximum of 600
VAC and it is quite possible to have voltages higher than that on a
transmission line.
