The HyperLink Lightning Protector Model ALQ2-NMNFB is a Quarter Wave DC-Short suppressor operating at 2.4 GHz. This unit is designed to pass the desired frequency while suppressing lightning surges. The ALQ2-NMNFB functions like a signal filter, operating within 2300-2700 MHz. Lightning strike electrical surges which operate at low frequencies (outside the ALQ2-NMNFB's frequency 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. Two ground lugs and terminals are provided directly on the lightning protector housing which provides superior grounding. Due to its superior RF performance this unit is ideal for IEEE 802.11b, 802.11g and 802.11n applications.Both connector ports of this unit are equally protected. This provides protection no matter which way it is installed. Either port can face the antenna and either port can face the equipment.The ALQ2-NMNFB features a bulkhead N-Female connector with a rubber "O"-ring seal for mounting through an enclosure wall. An optional stainless steel mounting bracket, HGX-LPMOUNT01 is also available.Operational Note: This 1/4 wave protector is not for use with coaxial cables carrying a DC voltage such as in the case of a remote-mounted amplifier or LNA. For applications requiring DC capability please see our Gas Tube version AL-NMNFB-9.
