INTRODUCTION

Each antenna is lightweight,
compact, rugged and has been
manufactured to ensure maximum
gain, low VSWR and high power
handling capabilities. Whether
testing inside a shielded enclosure
or outdoors, this antenna will display
efficient performance characteristics
through the broad frequency range
of 700 MHz to 18 GHz.

INTENDED PURPOSES

This equipment is intended for
general laboratory use in a wide
variety of industrial and scientific
applications and is designed to be
used in the process of generating,
controlling and measuring high
levels of electromagnetic Radio
Frequency (RF) energy. It is the
responsibility of the user to assure
that the device is operated in a
location which will control the
radiated energy such that it will not
cause injury and will not violate

regulatory levels of electromagnetic
interference.

PROFESSIONAL APPLICATION

The A.H. Systems Double Ridge
Guide Horn Antenna is used by
EMC test labs as well as
Regulatory, military and security
authorities for a variety of
applications. For example, the
Double Ridge Guide Horn Antenna
is suitable for MIL-STD approval
tests on electronic devices as well
as general field strength
measurements.

APPLICATIONS

The model SAS-571 Double
Ridge Horn antenna is a
broadband High gain antenna
with low VSWR. It has an input
handling capability up to 300
watts CW, and rugged design
make this horn antenna excellent
for both immunity and emissions
testing

GENERAL USE INSTRUCTIONS

The double ridge guide horn
antenna comes assembled and
ready to use. The antenna
mounting bracket is attached to
the antenna backwards for
packing purposes. The bracket
must be removed from the
antenna, turned over (so that
the bracket leg faces away from
the antenna), and re-attached to
the antenna. (The bracket is not
needed for mounting if the
tripod being used has an
Azimuth/Elevation Head.)

Attach the antenna to the
tripod azimuth and elevation
head through the hole on the
antenna bottom or the hole in
the mounting bracket. The ridge
guides determine the antenna
polarity: for horizontal polarity
they should be parallel to the
ground, for vertical polarity they
should be perpendicular to the
ground. Connect a cable
between the antenna connector
and the receiver.

NOTE: BE SURE TO USE A
CABLE RATED FOR HIGH
FREQUENCY WHEN
OPERATING ABOVE 5 GHz.

MAINTENANCE

Annual recalibration is
recommended to ensure reliable
and repeatable performance.
A.H. Systems experienced
technicians can recalibrate
almost any type or brand of
antenna.
