ACL-6000
The ACL-6000 CombiLog is a hybrid antenna with linearly polarized bandwidth. Simply stated, hybrid antennas are log periodic antennas with modified feed lines that include a set of low frequency antenna elements. Moreover, common-mode chokes are commonly installed to reduce common-mode currents flowing on the uter conductor of the coaxial feed line/receiver cable. A hybrid antenna can typically encompass, at a minimum, the frequency range of the combined antenna types by essentially combining a log periodic and biconical antenna.
As a receiving antenna, the ACL-6000 operates from 30 MHz to 6 GHz, and as a transmitting antenna, it operates from 80 MHz to 6 GHz.
The ACL-6000 is a qualification-level EMI test antenna for measuring regulatory conformance in accordance with the vast majority of regulatory requirements.
The ACL-6000 is similarly suitable for use as a transmitting antenna for product immunity tests within the frequency range of 80 MHz to 6 GHz. The ACL-6000 can also be used for test site comparisons, shielding effectiveness evaluations of large enclosures, field monitoring, site surveys, and other similar applications.
AC-220
The AC-220 Combilog is a broadband, linearly polarized hybrid antenna. Hybrid antennas are, put simply, log periodic antennas with the feed lines modified to include a set of low frequency antenna elements, commonly referred to as “bow-tie” elements. Additionally, common-mode chokes are typically installed to reduce common-mode currents flowing on the outer conductor of the coaxial feed line/receive cable. By essentially combining a log periodic and biconical antenna, a hybrid antenna can typically cover, at a minimum, the frequency range of the combined antenna types.
The AC-220 operates from 20 MHz to 2 GHz as a receiving antenna. Using typical conventional antennas, four separate antennas would be needed to cover the same frequency range.
The AC-220 Combilog Antenna is suitable for use as an EMI test antenna for qualification-level regulatory compliance measurements as per most regulatory requirements.
The AC-220 is equally suitable for use as a transmitting antenna over the frequency range of 80 MHz to 2 GHz. The antenna is driven by an RF power amplifier for the purpose of establishing radiated RF fields for product immunity tests. It is capable of handling power levels up to 500 Watts.
Notwithstanding the above applications, the AC-220 can also be used for test site comparisons, shielding effectiveness tests of large enclosures, field monitoring, site surveys, etc.
