The COL3 is electrically identical to the COL17 antenna. The COL3 is a ruggedised antenna, designed for use in the most extreme climatic conditions. The radome which houses the active elements of the COL3 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 alodined aluminium mounting tube supports the radome.
