Description
The ALQ2-DFDFB is a Broadband 1/4 Wave DC -Short suppressor designed for 800- 2250 MHz applications. This unit is designed to pass the desired frequency while suppressing lightning surges. The ALQ2- DFDFB functions like a signal filter, operating within 800 -2250 MHz. Lightning strike electrical surges which operate at low frequencies (outside the ALQ2-DFDFB operating range) are diverted through the protector’s short-circuit to the ground. The unit’s non-gas tube design, multi-strike capability and fast response time make it suitable for a wide range of applications. A ground lug is provided directly on the lightning protector’s housing, which allow for sup erior grounding. Both connector ports of this suppressor are equally protected. This provides equal protection no matter which way it is installed. The ALQ2-DFDFB features a 7/16 DIN Female Bulkhead connector with a rubber o -ring seal for mounting through an enclosure wall or panel.
