A.H. Systems AK-285R Shielding Effectiveness Antenna Kit
High Field Biconical Antenna, Folding
This Biconical antenna has a coaxial wound
balun that can handle High fields of RF energy.
Features
• Frequency Range of 20 MHz to 300 MHz
• Receive and Transmit
• Individually Calibrated (1, 3 and 10 Meter calibration included, horizontal
polarization)
• Rugged Construction
• Three Year Warranty
The SAS-544F Folding Biconical Antenna was the first EMC antenna designed for
portable compliance testing applications. This Biconical Antenna is designed with a
coaxial wound balun for increased power capability and intended for both transmitting and
receiving high electromagnetic RF fields. For rapid deployment, along with the mobility of
a small package, the Folding Biconical elements can be closed similar to an umbrella
allowing the antenna to be contained in an optional transit storage case. Whether testing
in a shielded enclosure, or outdoors, the rugged construction of the A.H. Systems
Biconical antenna will ensure long life, and reliable performance.
Assembly:The biconical antenna consists of the SAS-544F balun assembly, balun clamp
assembly and two folding biconical elements.
Operation: Attach the balun assembly to the tripod azimuth and elevation head with the
balun clamp. Screw the two biconical elements into the 'tee' end of the balun assembly.
Open the antenna elements completely and secure in open position by tightening the
knurled knobs in the element caps. Connect a cable between the antenna connector and
the receiver. The biconical beam pattern is similar to a dipole response.
