1000 watt multi wire broadband dipole
125 watt single wire broadband dipole in a limited space
configuration
The Barrett 912 series of broadband base station antennas
are designed for use in either an inverted “V”configuration,
912 Series Broadband Dipoles
900 series HF SSB base station antennas
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 light
weight and corrosion resistant, but are able to withstand wind
speeds in excess of 200km/h. The antennas are supplied
complete with an inverted “v” mounting harness, 30 metres
of coaxial cable and high quality waterproof connectors.

Single frequency wire dipole
915 Single Wire Dipoles
Single wire dipole antennas, spot-tuned to the required
operating frequency, are the most efficient antennas for use
900 series HF SSB base station antennas
in HF base stations. They are simple to install and have a
relatively narrow bandwidth and require little maintenance.
When several frequencies are required at a base station,
several dipoles can be stacked one above theother between
two towers. An antenna switch box BC91600 can be used to
switch to the required dipole depending on the channel.

In addition to the antennas described in this brochure, we can supply other antenna systems
including, rotatable log periodics, deltas, rhombics and conical monopoles to suit specific
customer requirements.

The Barrett 913 series helical dipole antenna is designed for use in
base station installations where the use of wire dipoles or
45
broadband antennas is impractical.
The construction and ease of assembly make the 913 Series
ideally suited to sites where space is restricted or where it may be

base station. In environments where man made noise causes a
problem when using a broadband antenna, signal to noise ratio is
improved by the narrow bandwidth characteristics of the
Helical Dipole .
