If you have an under-the-floor crawl space, you could probably bring
the coaxes in under the building through a vent (make sure to seal

floor in a convenient corner, and snake your coaxes up that way. Or,
cut out an opening and flush-mount a box with RF connectors in it.

Google "plenum wire" to find what kind of cable is required when using
plenums for any kind of electrical wiring (similar issues may apply
to other plastic materials as well).

Normal insulation can generate toxic fumes in the presence of heat from
a fire, capable of killing or incapacitating the occupants even before
the fire itself threatens them.
