Description
Features A range of high gain omnidirectional collinear antennas, the COL8 and COL12 are electrically identical and differ only in their physical construction. An operating bandwidth of 10 MHz is provided within VSWR limits of less than 1.5:1, making them suitable for single and multi-frequency applications. The antennas include internal DC grounding for lightning protection and the reduction of static noise. This negative beam tilt gradually increases with lower frequencies within the defined operational bandwidth. The result is an antenna that provides excellent null fill coverage and optimized range for antenna sites where average height above ground level is not greater than 2000m. • 6dBd gain omnidirectional pattern • Range of models to cater for varying environments • The radiating elements are constructed of alodined aluminum with all internal metal junctions welded to prevent the generation of intermodulation products and spurious emissions
