The 112515-75: It carries a 4 GHz frequency ceiling and a 500 V voltage rating, with a bayonet lock that gives a quick, secure mate. The 75 Ohm impedance makes this the version you reach for when the signal path is video, CCTV, or telecom baseband — the standard 50 Ohm BNC would reflect energy back into the line and degrade the waveform.
