I started with mine on the bottom but moved it to the top yesterday. When it was on the bottom, it was between the TV and the stand. I had an open slot that would just barely big enough to hold the sensor. I liked this placement for appeareances but it seemed to lose the signal up high. Since I'm tall, this affected my bat swing in baseball. The upper location seems to be better for baseball and still works for bowling, however the pointing function doesn't seem as good. I may fiddle with the sensitivity settings later today.
