Lightning protection cable penetrations

For the protection of communications equipment against overvoltage conditions, Selex ES has developed a coaxial conductor for use in the 0 – 18GHz frequency range.


This coaxial conductor offers the user a solution for safely discharging multiple surge currents.


An overvoltage condition that occurs between the inner and outer conductor is safely dissipated through a specially formed spark gap.


This conductor has been launched on the market and large numbers are in use.


Connector plug: type N connector female – female
Temperature range -55° to +90°C
Frequency-dependent return loss >25 – 17dB
Frequency-dependent insertion loss 0.05 – 0.25dB
