A.H. Systems SAS-544 High Field 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-544 biconical antenna is supplied with an antenna balun clamp. Place the SAS-544 balun assembly into the balun mounting clamp, attach the balun mounting clamp on to a tripod or azimuth and elevation head with a 1/4-20 thread. - Page 7 A.H. Systems SAS-544 High Field 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.
