A simple wire antenna will do as good a job on the hf frequencies.
Simply run a length of thin wire around the perimeter of the largest
outward facing window and attach to your receiver. Suspend it with
mini suction-cup hooks.

Or, run a length of wire around the perimeter of your listening room.
Just tuck it between the carpet and wall and nobody will be the wiser.

Thin multistrand wire is the best choice, and you can even use really
thin magnet wire for the window antenna.
