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.

The COL12 is electrically identical to the COL8 however it’s ruggedised design makes it ideal for use in the most extreme climatic conditions. The radome which houses the active elements of the COL12 was originally designed to serve as the mast of recreational sail boards and is immensely strong. The radome is coloured black to maximise solar heat retention and this has been shown to aid significantly in ice shedding. A large, 60mm dia.x 500mm aluminium mounting tube supports the radome. • 6dBd gain omnidirectional pattern • Range of models to cater for varying environments • The radiating elements are constructed of alodined aluminium with all internal metal junctions welded to prevent the generation of intermodulation products and spurious emissions
