Project Description



Data cable protection devices for transmission and reception technology with exchangeable gas discharge tube. Long endurance due to minimum contact erosion resulting from the large-area contact surface of the gas discharge tube.

  • Large-area contact surface of gas discharge tubes
  • Longevity due to minimum contact erosion at the inner conductor
  • For installation in conformity with the lightning protection zone concept at the boundaries from 0A – 1 and higher
  • Available in 50 Ω and 75 Ω technology
  • Application: BOS radio, SAT and TV systems, mobile radio
