4496 Product Series

The 4496 product series are coaxial surge protective devices for hopf high frequency antenna systems supporting the Global Navigation Satellite Systems (GNSS) GPS, Galileo, GLONASS, and BeiDou for precise and reliable time synchronization.

  • Small form factor device for loop in antenna cable
  • Low insertion loss
  • Removable Gas Degassing Tube (GDT)
  • DC . pass
  • Bi-directional protection
  • Mounting kit for wall mount, plate mount or DIN rail mount according to IEC 60715 TH35
The 4496 series surge protectors are designed to protect hopf GNSS applications supporting GPS, Galileo, GLONASS and BeiDou hopf applications against lightning and transit.
It constitutes the first level of protection for sensitive equipment and can be derived multiple times. The 4496 series of products are waterproof and equipped with replaceable gas discharge tubes (GDT).
