PLEASE READ THIS MANUAL IN ITS ENTIRETY BEFORE ATTEMPTING INSTALLATION.

This kit contains the following:

1x Antenna Assembly

1x coaxial cable

Halyards and pulleys required to hoist and support the antenna are not supplied, however they can be purchased sepa-

rately from Barrett Communications (Halyard and Pulley Kit P/N BCA91201). It is recommended that the halyards used to 

support the antenna be either UV stabilised dacron cord or wire rope and that pulleys be of stainless steel construction.

For a 10-15m mast with an antenna in inverted V configuration, rods or stakes should be inserted into the ground at least 

9m away from the mast in order to secure the antenna ends.  

As with all antenna installations, ensure the antenna is as far from sources of electrical interference as possible and in a 

position that makes it impossible for the antenna to come in contact with high voltage overhead mains wiring.

It is highly recommended that antennas be installed by suitably qualified personnel.

Horizontal Configuration

Inverted V Configuration

Introduction

Barrett 912 Multiwire broadband 

(150W) can be mounted in a hor-

izontal  configuration  with  a  10-

15m mast or in an Inverted V con-

figuration with a 10-15m mast (. 

The required minimum distance 

between the masts is 32 metres 

for horizontal configuration. 

Compatible masts

10m Mast with nylon guys (P/N BC90205/FR/PR)

10m Mast with stainless steel guys (P/N BC902906/FR/PR)
