The kit's three pieces (connector body, end cap, ferrule) cover the full termination hardware; you supply the cable and the crimp tool for the ferrule. The snap-on coupling locks with an audible click and releases with a straight pull — no threads to turn, which speeds up repeated connects and disconnects in test setups.","metaTitle":"903-289P-51A2 SMB Plug, 50 Ohm, 4 GHz, RG-316, Right Angle","metaDescription":"903-289P-51A2 SMB plug, female socket, 50 Ohm, 4 GHz max, for RG-316 cable.
