I'm considering a vertical dipole array, one each in 3 corners of a
triangle around the outside of my apartment wall. I'm on the lower
floor, of course. Each vertical dipole will be disguised as a
stereotypical wooden birdhouse that you find at the craft store,
supported by wooden poles with wire cores.

I see some surprised birds in the picture.....;-)
