Antenna Options
The standard detachable portable antenna supplied with the access point is a
multi-purpose antenna suitable for a variety of environments, including office
LANs, physical plants, and factory floors. If your site has special requirements that
might be served by different types of antenna, four optional antenna models are
available, as shown below:
Omnidirectional Antenna
The fiberglass omnidirectional
antenna (model number 3CWE490)
is designed for use in harsh indoor
environments. It can be centrally
located on the ceiling to provide
uniform coverage over a wide area.
This antenna features a built-in
matching network that eliminates
the need for a ground plane.
This antenna can be mounted on
the ceiling by means of a standard
ceiling-mount bracket. Before
installing, ensure that access is
available for cable routing.
Ceiling Mount Omnidirectional Antenna
The ceiling-mount omnidirectional
antenna (model number 3CWE492)
is designed to cover large, open
areas. It should be located at or near
the center of the ceiling of a large,
open area (such as an open office
space divided into cubicles) to
provide uniform coverage in all
directions.
It is mounted by means of a single-hole stud mount, and so can be fixed easily to
drop ceiling tiles or to a solid ceiling surface where cable routing access is
available.
