The 144-175 MHz COL range is a series of “cut to frequency” 3dBd gain vertical collinears. The range includes antennas suitable for simplex, duplex and rugged applications. All of the antennas 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 alodine finish of the aluminium mounting tube provides a conductive surface which ensures effective earthing when mounted.
The COL35 is a high gain omnidirectional collinear antenna specifically designed for the most extreme conditions. It incorporates sleeved broadband dipole elements enclosed with a ruggedised, heavy walled fibreglass radome. The radome is coloured black to maximise solar heat retention and this has been shown to aid significantly in ice shedding. A heavy duty hot dip galvanised steel mounting tube supports the radome.
