Lightning Protector. Protects amplifier from surges resulting from outside antenna being struck by lightning

Cell phone antennas and amplifiers are frequency specific (more info).

Protect sensitive electronic communications equipment from the damaging effects of lightning strike electrical surges.


  • Reliable performance from DC-3GHz
  • High quality construction
  • Easily replaced gas tube element
  • Multi-strike capability
  • Bi-directional protection
  • Amplifier friendly - protector will pass DC

This model features wide-band operation up to 3GHz. Due to its superior RF performance, this unit is ideal for IEEE 802.11b/g Wireless LAN applications, as well as ISM, MMDS, Cellular, iDEN and PCS applications. Since this protector will pass DC, it is suitable for applications where DC is carried through the coax cable such as remote amplifiers and LNAs.

This unit offers multi-strike capability via a replaceable gas tube element. A ground lug and terminal are supplied directly on the lightning protector housing providing superior grounding.

Protector is inserted inline between outside antenna and amplifier. The protector does not connect directly to the amplifier. Typically, a 2' LMR-400 jumper cable is used to connect the protector to the amplifier although any length of LMR-400 coax may be used.

For example, you can run LMR-400 coax from the Yagi on the roof to the lightning protector (mounted just outside the building) and then another run of LMR-400 coax cable from the lightning protector to the amplifier mounted in the building.

The lightning protector must be grounded.


  • Frequency Range: 0-3GHz
  • VSWR: 1:1.3 Max
  • dB Loss: 0.4dB Max
  • Impedance: 50 Ohm
  • Gas Tube Voltage Rating: 230V
  • Connectors: N/Female, both ends (one end is bulkhead)

Please note that while lightning protection will help guard against amplifier damage due to a lightning strike it does not guarantee it.
