Time & FrequencySolutions 4496 Product Series GNSS Surge Protective Device 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. Key Features ■ Small form factor device for looping into the antenna cable ■ Removable gas discharge tube (GDT) ■ 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). 4496 Product Series Product Sheet GNSS Surge Protective Device v01.03 1 / 4
