Axially compressible, high bandwidth F-connectors designed for conventional installation hand tools for interconnection with coaxial cable. Each connector has a rigid nut that is axially and rotatably secured to a molded plastic, tubular body. A rigid, conductive post coaxially extends through the connector, linking the nut and body. A post barbed end penetrates the cable within the connector. The body has a tubular shank with an obstruction-free surface and an integral stop ring. A tubular, metallic end cap is slidably fitted to the body shank, and thereafter forcibly compressed lengthwise, with travel limited by the stop ring. No detented structure is formed on the body, and the end cap can irreversibly assume any position, being held by end cap teeth. A tactile system comprising convex projections on the stop ring complemented by a resilient O-ring on the end cap helps installers determine correct placement through the sense of touch.
