Page 3: Introduction
A.H. Systems SAS-521-4 Bilogical Antenna INTRODUCTION The SAS-521-4 Bilogical Antenna (also known as a hybrid log periodic, biconical antenna) is a lightweight antenna that has been designed to ensure medium gain, low VSWR and high-power handling capabilities. Constructed of lightweight aluminum, the SAS-521-4 Bilogical Antenna has been manufactured to operate over a very wide bandwidth. -

A.H. Systems SAS-521-4 Bilogical Antenna OPERATING INSTRUCTIONS ASSEMBLY INSTRUCTIONS The SAS-521-4 Bilogical Antenna is shipped with the triangle and window elements removed from the boom; this allows for easy transportation. The Bilogical Antenna also comes with the LPM-510 tripod mounting adapter that is already assembled onto the antenna. - Page 7 The horizontal beamwidth of the Bilogical is approximately 45 degrees and it should be pointed or aimed in the direction that the received signal is coming from. © A.H.

Page 14: Maintenance
ANNUAL CALIBRATION To ensure reliable and repeatable long-term performance, annual re-calibration of your antennas, preamplifiers and current probes by A.H. Systems experienced technicians is recommended. Our staff can calibrate almost any type or brand of antenna. It is always up to the user to determine the appropriate interval for calibration certification based on the requirements of the end users specific test/application. -
