VHF Custom Tuned Collinear Antenna 144-175MHz 3 DBd – 3.2kg

Rated 5.00 out of 5 based on 1 customer rating

(1 customer review)

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 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 aluminum 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.
