A.H. Systems Model Active Monopole Antennas OPERATING INSTRUCTIONS ASSEMBLY INSTRUCTIONS To prepare the antenna for operation, attach the telescoping rod antenna element to the top of the high impedance preamplifier. Adjust the rod length to 41” (1.04 meters). Do not operate the Monopole antenna with the Battery Charger connected. - Page 7 A.H. Systems Model Active Monopole Antennas GENERAL USE INSTRUCTIONS The calibration tables shown provide a listing of the frequency of operation and its antenna factor in dB/m. The field strength is the receiver voltage in dBV plus the antenna factor (refer to the antenna factor calibration) plus any cable loss.

A.H. Systems Model Active Monopole Antennas CALIBRATION Equivalent Capacitance With changes to our Active monopole antenna (converting the input connection from a BNC to a more rugged ¼-20 input) our element diameter changed to 6.17mm (Average). It is our recommendation to use a 12 pF for the ECSM fixture for an element height of 41” (1.04 meter) as per ANSI C63.5:2017 and CISPR 16-1-6:2017. - Page 9 A.H. Systems Model Active Monopole Antennas Active Monopole Calibration The antenna factor for the rod antenna shall be determined by measuring the signal transfer characteristics with the matching device and assuming that the antenna is a short monopole with an infinite ground plane.

MAINTENANCE To ensure reliable and repeatable long-term performance, annual re- calibration of your active monopole preamplifier by A.H. Systems’ experienced technicians is recommended. Our staff can recalibrate almost any type or brand of antenna. For more information about our calibration services or to place an order for antenna calibration, visit our website at www.AHSystems.com or call (818) 998-0223. - Page 12 A.H. Systems Model Active Monopole Antennas FAQ’s Q: Is your output connector bonded to the network case per MIL-STD 461F/G? A: The signal output connector is bonded to the antenna matching network case. Q: The product page states that the antenna includes an 18” ground plane but the standard I’m testing to requires at least a 60cm ground plane?
