The 66-88 MHz COL range is a series of “cut to frequency” 3dBd gain vertical collinears. The range includes models suitable for simplex, duplex and heavy duty applications. They all include internal DC grounding for lightning protection and the reduction of static noise. Drainage vents at the base allow the antennas to ‘breathe’ and thus prevent condensation build up.
The COL1 is an electrically identical internal design to the COL16 with ruggedised construction, designed for use in the most extreme climatic conditions. The radome which houses the active elements of the COL1 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. The antenna is fitted with a large, 60mm diameter alodined aluminium mounting tube.
