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.
