VHF Collinear Ruggedized Antenna 144-175MHz Custom Tuned – 3 DBd

Rated 5.00 out of 5 based on 1 customer rating

This 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 aluminum mounting tube provides a conductive surface that ensures effective earthing when mounted.

Description

This is electrically identical to the COL17 antenna. The COL3 is a ruggedized 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 colored black to maximize solar heat retention and this has been shown to aid significantly in ice shedding. A large alodined aluminum mounting tube supports the radome.
