Barrett 913 helical dipoles
The Barrett 913 series helical dipole antenna is designed
for use in
base station installations where the use of wire dipoles or 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 necessary
to periodically dismantle in order to
relocate a temporary 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 913 Helical Dipole .
The hub is designed to be mounted on either a 50mm
diameter support
mast or an existing tower. The antenna comes complete with
30 metres
of RG58 coaxial cable and high quality C32-21 waterproof connectors.
Barrett 913 Antennas are ready to erect, in kit form,
with threaded
mounting bolts which attach directly to the central hub.
