VHF Collinear 144-175MHz Custom Tuned - 3 dBd - 3.2kg


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.

  • COL17
The COL17 is suited for broadband and duplex applications designed to cater for transmit to receive separations of up to 5.0 MHz. The antenna is a series fed collinear which is housed in a heavy duty tapered fibreglass radome, fitted to a ruggedised alodined aluminium mounting tube. The COL17 (and the electrically identical COL3) have been specifically designed to maintain stable vertical radiation pattern characteristics at the extremities of the tuned bandwidth, ensuring reciprocity of transmit and receive signal.
