I raise the bottom sash of the window and install a metal plate across
the opening.
The sash must be sealed to both the plate and to the upper sash to
prevent leaks. The plate itself is connected to the main shack ground
just outside. Bulkhead style connectors both UHF and N are used for the
coax leads. I used an octal socket for the rotor cable and an F
connector for a power lead to a mast mounted 432 preamp. The point is
that all the connections can be easily removed if there is lightning in
the area. I did the same things some years back for my Dad's house in
Florida; unfortunately this was after having some lightning damage.

I have also done similar, but a little differently. I used two boards
and drilled between them for the wire diameter. This created two
half-holes in the edge of each board. I laid the wires down in the
holes and laid the other board on top. This sorta worked. I still
had to seal between the glass and the top edge of the bottom window
(we had old recessed windows) so I drilled the holes in the floor.
