UltraS BNC Adapters

JawDropper UltraS connectors are developed to enhance electrical and mechanical performance with the stable, push and turn interface of a traditional BNC. The UltraS series provides tactile feedback and a positive lock for quick and guaranteed mating. The name UltraS derives from its 4-times-smaller size than traditional BNC with both 50 and 75-ohm impedance. The same cable prep and termination specifications of legacy broadcast connectors make adopting HD-BNC seamless.
