Gas Tube Surge Arrestor Type N male female, bulkhead

Rev : G | Rev date : 07 Jan 2021

Surge arrestors are designed to protect wireless base stations, switching centers and transmission line from the damaging effects of extreme high voltage surges caused by lightning strikes. Lightning strikes, even on grounded systems, can implant crushing voltages on RF transmission lines, creating voltage spikes on the center conductor of coaxial cable and putting the network out of commission. The new RFS lightning protection devices are designed and tested to the most demanding specifications. They are rated to protect against both direct and indirect multiple strikes in the harshest environments imaginable. Their rugged construction utilizes solid metal housings, beryllium-copper contacts and superior plating, which results in outstanding system protection and operating continuity.


  • Broadband operation  DC to 2.5 GHz
  • DC continuity on center conductor for reliable operation
  • Replaceable 230 volts gas capsules for easy maintenance
  • compliancy to IEC 61643-21
