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.
