But in emergency/expedient situations, it would be really handy if one
could pass at HF, say, 100 watts of RF energy through a window (I
visualize some foil strips and an inductor or two to "tune out" the
capacitance) to an external antenna.

In an emergency I'd say... uh... just leave the window open? :-)

But be sure to bring a hefty brick along to create the opening in the first
place

The OP's dilema was that the window COULD NOT open, and therefore some
way to pass RF through glass would have been Useful.

Computer software consists of only two components: ones and
zeros, in roughly equal proportions. All that is required is to
sort them into the correct order.
