Positioning Antennas
In general, antennas should be mounted as high as practically possible and free of
obstructions. In point-to–point application, position both antennas at the same height and in a
direct line of sight to each other to attain the best performance.
For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For
omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single
AP application, place omni-directional antennas as close to the center of the coverage area as
possible.
For directional antennas, point the antenna in the direction of the desired coverage area.
