BNC style connectors are miniature, light-weight, weatherproof interconnecting devices characterized by their two-stud, quick disconnect bayonet lock coupling arrangement. Their design functions satisfactorily from DC to 11 GHz in static applications, or from DC to 4 GHz in applications involving vibration. The connectors typically yield a low VSWR (reflected signal) to 4 GHz. Primary applications include radio telecommunications, broadcast equipment, medical equipment, computer, Precision Video, High definition studio broadcast, video switching and test instrumentation where frequent coupling and de-coupling are necessary. Bomar's BNC's are available in an extensive variety of configurations and cable sizes and are impedance matched to either 50 ohm or 75 ohm.
