Pillar- or Wall-Mount Omni Antennas


Designed with the retail market in mind, the pillar-mount antenna pictured in Figure B-7 comes from Telex Communications. It was designed to be mounted to a building-structure pillar or to an inner-building wall. It also works well when placed on an outside corner of two walls. It has a fabric covering over it, allowing it to blend into the surrounding environment extremely well. This antenna supports diversity and is provided with dual-feed cables for the AP.
