Product Overview
Bomar BNC connectors are miniature, lightweight, and weatherproof
interconnecting devices featuring a two-stud, quick-disconnect
bayonet lock coupling. They offer reliable performance from DC to
11 GHz in static applications and DC to 4 GHz in vibrating
environments, typically yielding a low VSWR up to 4 GHz. These
connectors are ideal for radio telecommunications, broadcast
equipment, medical equipment, computer applications, precision
video, high-definition studio broadcast, video switching, and test
instrumentation requiring frequent connection and disconnection.
Available in 50 ohm or 75 ohm impedance matched configurations,
Bomar's BNCs come in an extensive variety of configurations and
cable sizes.
