Discone Antenna
The AX-71C antenna is a compact VHF/UHF
omni-directional receiving and transmitting
antenna for professional and amateur
applications.
(AX-71C pole mounted using WR-AC-01 clamps)
The antenna is ideally suited for wide band
surveillance and monitoring and reception of
VHF/UHF communicationswhere its omni-
directional characteristics and high gain can be
used to advantage.
The AX-71C offers a very good VSWR figure of
less than 1.5:1 for the VHF/UHF bands
The antenna covers the frequency range of
25MHz to 1500MHz.
While designed to be entirely general-purpose
and to perform well with third-party equipment,
the WiNRADiO AX-71C Wideband Discone
Antenna is especially suitable for the WiNRADiO
range of VHF/UHF receivers.
Its construction from high-grade stainless steel,
alloy and aluminium will ensure trouble free
operation for many years.
Rapid deployment is made possible by the
antenna’s simplified design and assembly.
Connect the feed-line, attach the radials and
mount the antenna and its ready to use. No
tuning or alignment is required.
The antenna should be pole mounted and clear
of objects that may effects its performance such
as metallic objects and other antennas.
