Description
This is electrically identical to the COL8 however its ruggedized 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 sailboards 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 aluminum with all internal metal junctions welded to prevent the generation of intermodulation products and spurious emissions
