ZyAIR B-4000 Hot Spot Gateway
D-2 Antenna Selection and Positioning Recommendation
• 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.
Connector Type
The ZyAIR is equipped with a reverse polarity SMA jack, so it will work with any 2.4GHz wireless
antenna with a reverse polarity SMA plug.
