SPDs for Coaxial Connection

DS-L4-7/16 F/F

Combined lightning current and surge arrester with maintenance-free quarterwave technology for multi-frequency applications (multi-carrier systems). The arrester is also capable of discharging high partial lightning currents. No remote supply as the arrester represents an electrical short-circuit for low-frequency signals. Broadband device for all 4+3G services.

  • Maintenance-free combined lightning current and surge arrester for multi-frequency
  • applications
  • Maximum transmission and PIM performance
  • For installation in conformity with the lightning protection zone concept at the boundaries from 0A – 2 and higher
