Usage

 

  • A crimp connector is used to terminate the end of a coaxial cable to allow connection to an RF device or antenna

  • Each series of connector differs by method of connection, size, and electrical properties, allowing a technician to select a connector to best match the intended purpose

  • Most crimp connectors consist of three components - the connector body, pin/socket, and crimping ferrule

  • Terminating a coaxial cable with a crimp connector requires three tools - a wire stripper/cutter, soldering iron, and hex crimp

  • You can find instructional videos on crimping most connectors on YouTube.
