A coaxial cable connector includes a body configured to engage a coaxial cable having a conductive electrical grounding property, a post configured to engage the body and the coaxial cable when the connector is installed on the coaxial cable, a nut configured to engage an interface port at a retention force, and a retention adding element configured to increase the retention force between the nut and the interface port so as to maintain ground continuity between the interface port and the nut when the nut is in a loosely tightened position on the interface port.

Calibration devices, systems, and methods for push-on RF connectors are described. A male calibration connector can include a removable detent portion. With the removable detent portion removed, the male calibration connector can connect to a female calibration standard during a calibration process. With the removable detent portion installed, the male calibration connector can connect to a female push on connectors. Female calibration connectors and male calibration standards are also described.

A contact device includes a first contact element extending along a straight line and a second contact element inclined with respect to the first contact element. The first contact element has a connecting body extending along the straight line, a first contact portion, and a flap. The first contact portion has a first contact socket. The flap is connected to a first fixed end at a first side of the connecting body. The first contact portion is connected to the connecting body. The flap extends along the first straight line to the first contact portion and a free end of the flap is arranged at a distance from the first contact portion. The second contact element has a second contact portion engaging the first contact socket and electrically contacting the first contact portion.
