The 5.2 dBi Mast Mount Vertical Omnidirectional indoor/outdoor antenna is
designed for WLAN applications for frequencies of 2400 MHz to 2500 MHz
. The antenna is
omni directional and has a nominal gain of 5.2 dBi. It is designed to be
mounted on a round mast or pole. The base of the antenna has an aluminum
section, which gives it enough strength to withstand being clamped. This
antenna is delivered with a hose clamp and an aluminum friction bracket for
mounting. A separate mast to which the antenna will be clamped, must be
provided. The mast mount antenna is designed for industrial applications. In
outdoor applications, the antenna cable end must be facing downward. In indoor
applications, the cable end should be facing the ceiling. The dimensions and
radiation pattern are shown in Figures
and
.
The 12
dBi antenna, shown in Figure
, is only for
outdoor, long-range applications. The AIR-ANT24120 offers an efficiently
designed fiberglass radome, which minimizes distortion and provides for maximum
range and better coverage than the previous antenna AIR-ANT4121. This antenna
might be used in the center of a point-to-multipoint bridging configuration. It
could also be used in a central area, which provides longer range connections
to an access point. The antenna, as with all outdoor-only antennas, has a
short, 30.48 cm (12 in.) coax pigtail, which makes it necessary to utilize
antenna extension cables. The dimensions and radiation patterns are shown in
Figures
through
.
This
antenna is delivered with a set of U-bolts and friction brackets. The antenna
must be mounted to a solid mast. The base of the antenna has a metal section,
which gives it enough strength to withstand being clamped. This antenna is
vertically polarized and must be mounted perpendicular to the ground with the
pigtail on the bottom. It has a plus and minus 3.5 degree beam spread from
perpendicular.
The Cisco Aironet 1400 series outdoor wireless bridge
9-dBi omnidirectional antenna is an optional antenna used with the 1400 Series
Outdoor Wireless Bridge
. This
non-diversity, vertically polarized antenna operates in the UNII-3 band (5725
to 5825 MHz). The antenna is designed to be mast-mounted in an outdoor
environment. The antenna is used at a hub site in point-to-multipoint
configurations. The antenna is not compatible with other Cisco Aironet radio
products operating in the 5-GHz frequency band. The radiation patterns are
shown in Figures
