from 6 inches square to 24 inches square, and use that as a through
the window capacitor. Hook up your indoor antenna lead to the inside
plate, and your external antenna leadin to the outside plate.
Make sure you have suitable lightning protection, since it is a mostly
ungrounded feed through. Put the lightning protection on the outside
part of the system.
One other mentioned inductors, and that is also a good approach.
I would use a pair of helical pancake coils (like the ones used in
early spark sets), as the coupling system.
For average receiving use, either system is entirely non-critical
in their sizing. If you want to get picky, you can tune them in
series or series/parallel mode to match most anything.
Good Luck
