  • Modular wireless broadband antenna tower
    Patent number: 6606075
    Abstract: A preconfigured antenna assembly for use in a target topographic region. The antenna assembly includes an antenna chassis covered by a radome cover and a set of antennas mounted to the chassis. The mounting mechanism for each antenna allows each antenna to be aimed by adjusting an angle of inclination between a long axis of the antenna and a plane defined by the antenna chassis. The antennas are separated by an angular and linear spacing to minimize interference between adjacent antennas and provide a desired signal coverage for the antenna assembly.
