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.
