A.H. Systems SAS-543 High Power Biconical Antenna OPTIONAL EQUIPMENT The following is a recommend accessory list for the SAS-543 High Power Biconical Antenna: CONNECTING ACCESSORIES: SAC-211 Standard 3 meter N(m) to N(m) RF cable made with RG-214/U. Other cable types available upon request. -
Page 6: Operating Instructions
MOUNTING INSTRUCTIONS The SAS-543 biconical antenna has two 1/4-20 mounting holes on the base of the balun. Attach the antenna to the azimuth and elevation head (AEH-510) through the screw hole in the antenna base. The azimuth and elevation head (AEH-510) mounts to the tripod (ATU-510) top and allows the antennas to be rotated 360 degrees and tilted between horizontal and vertical polarization. - Page 7 A.H. Systems SAS-543 High Power Biconical Antenna OPERATING INSTRUCTIONS Once the antenna is mounted to a mast or tripod, connect an N-type coaxial cable from the antenna to a receiver or RF generator. The cable should be matched to 50 ohms, relatively low loss and adequately shielded against leakage such as RG-214/U or better.

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. -
