I use this simple bracket to mount my Broadlink RM3 behind my TV. My wall bracket has a nice nook where I can just slide in from the side and it holds it securely. The bracket will hold it upside down (by the USB connector) or right-side up (by the taper). My TV's sensor is on the bottom corner, so this points down at it and works perfectly.
