Omnidirectional Antennas
Mast antennas

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 and .
