Features ■ ■ ■ ■ ■ Protects subscribers and equipment from destructive power crosses and lightning surges Reduces frequency of service calls Increases reliability of network operation Reduces cost of network maintenance UL Listed per UL 497* ® 1965 Series – 50 Ohm Coaxial Surge Protector The Bourns 1965 Series Coaxial Surge Protector is intended for use with low power VHF and UHF transmitters, 2-way base station transceivers, and receive-only systems. All models provide GDT technology. The 1965 arrester is symmetric and bidirectional. Either end may be used for the input or output. Various power and voltage choices are available - see specifications below for proper selection. Available with a choice of connectors. Note: The arrester ground plate is common with the connector body; hence the coax cable shields will be grounded at their connection to the arrester.

The above curves apply to systems with a VSWR of 1.2:1 or less. Choose the protector whose curve lies first above the power-frequency coordinates of the radio system. For systems with a VSWR in excess of 1.2:1, or for a more exact determination if desired, multiply the actual radio power by the expression 0.83[2xVSWR÷(1+VSWR)]2, and use this new power value to enter the graph.
