• Broadband: 20 MHz to 2 GHz
• Minimizes antenna switching
• Transmit and receive capabilities
• Individual calibration

The AC-22- Combilog is a linearly polarized, broadband hybrid antenna. A log period antenna with the feed lines modified to include a set of, what is commonly referred to as "bow-tie" elements, which are low frequency antenna elements is the basic characteristic of a hybrid antenna. To reduce the the flow of common-mode currents on the outer conductor of the coaxial feed line/receive cable, common-mode chokes are typically installed. At a minimum, the frequency range of a log periodic, and biconical antenna can be covered by a hybrid antenna.

Four separate typical conventional antennas would be needed to cover the 20MHz - 2GHz frequency range that the AC-220 operates in.

Use as an EMI test antenna that meets most regulatory requirements for qualification-level regulatory compliance measurements is a suitable application for the AC-220 CombiLog Antenna. Transmitting over the frequency range of 80MHz - 2GHz is something that the AC-220 is equally suited for. For the purpose of establishing radiated RD fields for product immunity tests an RD power amplifier drives the AC-220 CombiLog Antenna. Handling power levels of up to 500 Watts is within the capabilities of the AC-220. Site surveys, field monitoring, shielding effectiveness tests of large enclosures, and test site comparisons are some of the applications that the AC-220 can also be used for.

To easily and quickly change the antenna polarization the AC-220 mounting assembly incorporates a hinge mechanism. To allow the AC-220 to be affixed to a tripod, antenna mast, or other mounting structure the mounting assembly is equipped with a standard 1/4inch by 20 mounting hole. Recommended supports for this antenna are Com-Power's AM-400 Antenna Mast & AT-812 Tripod.
