How to Put on a Compression BNC Connector
Compression BNC connectors have only one part: the connector itself. However, to compress one, you need a tool that costs around $100, and has no other use than to install these connectors. BNC compression connectors fit on various types of radial ground (RG) coaxial cables that have a solid center conductor surrounded by a braided wire shield. They carry signals up to 11 GHz for various applications, and connect to equipment with a one-quarter turn twist for easy connection and disconnection.

The "bayonet" lugs on a female BNC connector hold the collar in place. Strip one-half inch of the outer insulating material off the cable using a scissors or wire stripper. Be careful not to nick the braids.

Strip the shield and insulator back from the end of the cable one-quarter inch. Be careful not to nick the center conductor. Straighten out the braids of the shield and fold them back over the outer insulator.

Tips & Warnings
Dimensions may vary slightly with different brands of compression connectors. Read the instruction sheet that comes with your connector for exact distances.
Select a connector appropriate for your coaxial cable, and a compression tool made for that connector.
When pushing the cable into the connector, make sure the center conductor goes into the center pin socket.
