Barrett 912 Multiwire broadband(150W) can be mounted in a horizontal configuration with a 10-15m mast or in an Inverted V configuration with a 10-15m mast (.The required minimum distance between the masts is 32 metres for horizontal configuration.
The Barrett 912 series of broadband base station antennas are designed for use in either an inverted “V” configuration, using a single mast, or a standard dipole configuration, between two masts.
In the inverted “V” configuration the 912 provides a more omni directional radiation pattern. All broadband antennas in the series are designed to provide optimum performance over a wide HF spectrum, without the need for antenna tuners. Using high quality stainless steel and glass reinforced composites the 912 series of broadband antennas are lightweight and corrosion resistant, but are able to withstand wind speeds in excess of 200 km/h.
The antennas are supplied complete with an inverted “V” mounting harness, 30 metres of coaxial cable and high quality waterproof connectors.
Halyards and pulleys required to hoist and support the antenna are not supplied, however they can be purchased separately 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.
