A.H. Systems SAS-542 Biconical Antenna OPERATING INSTRUCTIONS ASSEMBLY INSTRUCTIONS The SAS-542 Biconical Antenna is shipped with the elements detached from the balun. Attach each element to the Biconical balun tee assembly. MOUNTING INSTRUCTIONS The SAS-542 biconical antenna is supplied with an ABC-B Balun mounting clamp. - Page 7 A.H. Systems SAS-542 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. The cable should be matched to 50 ohms, relatively low loss and adequately shielded against leakage such as RG-214/U or better.
