Base Station Radiation Pattern (Wall Mounting)
When the base station is mounted vertically on the wall, the radiation pat-
tern is approximately a 2 to 1 (2:1) forward to back ratio. This is due to the
absorptive effects of the wall on the signal and the orientation on th the flat
antenna shape aimed diagonally off of the corners (Figure 2-15).
