Whats the difference between compression and crimping adapters?

F-type connectors have a center pin for the center conductor, and the shield connects to the body of the connector. A "F" connector screws onto the threaded connector on the TV or other component.  On a crimp connector, the outer shield of the cable crimps or squeezes onto the body of the connector. The center conductor either crimps or solders to the center pin of the connector.  In a compression connector, the outer shield of the cable is compressed against the body of the cable with a threaded nut. The center conductor either crimps or solders to the cable. You need a special crimping tool to connect the shield to the crimp F connector. But you only need standard hand tools to connect the shield of a compression F connector. The crimp connection only takes a few seconds to make. As a professional installer, you would benefit from making faster crimp connections. But you cannot disassemble a crimp connection.
