Bomar's BNC connectors are miniature, lightweight, and weatherproof interconnecting devices featuring a two-stud, quick disconnect bayonet lock coupling arrangement. They are designed for reliable performance from DC to 11 GHz in static applications and DC to 4 GHz in applications involving vibration, typically yielding a low VSWR to 4 GHz. These connectors are ideal for 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. Available in an extensive variety of configurations and cable sizes, Bomar BNCs are impedance matched to either 50 ohm or 75 ohm.
