Antennas 15
• Directional antennas concentrate the RF signal in a beam, like a flashlight. The angle of the beam
width determines the direction of the coverage pattern; typically ranges from 20 degrees (less
directional) to 90 degrees (very directional). The directional antennas are ideal for hallways and
outdoor point-to-point applications.
Positioning Antennas
In general, antennas should be mounted as high as practically possible and free of obstructions. In point-to –
point application, position both transmitting and receiving antenna at the same height and in a direct line of
sight to each other to attend 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.
