4496 Product Series
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, BeiDou and IRNSS/NavIC for precise and reliable time synchronization.
- Small form factor device for looping into the antenna cable
- Low insertion loss
- Removable gas discharge tube (GDT)
- DC-pass
- Bi-directional protection
- Mounting kit for wall mounting, mounting plate or mounting on DIN rail according to IEC 60715 TH35
The 4496 product series surge protectors are designed to protect hopf GNSS applications supporting the Global Navigation Satellite Systems (GNSS) GPS, Galileo, GLONASS, BeiDou and IRNSS/NavIC against lightning and transients. They form the first level of protection for sensitive equipment and can derive multiple times. The 4496 product series is waterproof and equipped with replaceable gas discharge tubes (GDT).
