Since the brackets I found all came in two-packs, that’s probably a great idea. I chose a 2.5" corner bracket (widest I could get) which seems to work well. More $ but cheaper than the plastic mini speaker shelves I had planned on getting. Since I had magnets sitting around, I’m using those atm. I may be moving the bracket from the wall-mounting spot to further into the window. I have to put up the motion-sensitive light before I decide best viewpoint.
Has anyone tried this one? That looks like it would work well.
