Optional Antennas
When the AP is configured to support wireless clients, you may need the Range
Extender antenna to improve signal quality when the PC Card in the AP is shielded.
In a LAN-to-LAN configuration, you may need to install outdoor antennas, especially
when the APs are located in separate buildings.
Range Extender Antenna
The RoamAbout PC Card in the AP has two integrated antennas that perform best in
an open environment with as few obstacles as possible. Use the Range Extender
Antenna (Figure 1-4) to ensure optimal transmission and reception quality for
situations where the integrated antennas are shielded, such as:
You can connect the Range Extender antenna to the PC Card by inserting the connector
into the socket on the extended side of the PC card. To protect the socket from dust, it
is shielded with a cap. Remove this cap before you connect the antenna.
The Range Extender antenna has a mounting bracket and a base for vertical positioning
that allows you to place the antenna on top of a table or filing cabinet, or hang it on the
wall or ceiling.
Many computer monitors support a degauss option. The electromagnetic
discharge that may occur when degaussing the monitor may cause damage to the
antenna. To avoid damage, do not place the Range Extender Antenna on top of, or
too close to, a monitor.
The PC Card is close to metal surfaces.
The AP is installed in a hidden location, e.g. under a desk or inside a cabinet.
Objects shield the PC Card.
