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.
