Hirose Electric GT21 Series Automotive Antenna Connectors feature a coaxial termination system that allows crimping of the center and outer conductors in one easy step. The cable assembly is finished without touching the center conductor, which provides precise center conductor positioning and produces consistent, repeatable cable assemblies. The one-step termination process delivers a precision assembly in significantly less time. GT21 enhanced connectors are designed to save space and are up to 10% smaller than competing designs. GT21 Series devices significantly reduce the required PCB real estate, resulting in a more compact antenna design solution. With a voltage standing wave ratio (VSWR) of 1.5 maximum (DC to 2.5GHz), the compact GT21 connector features excellent performance characteristics in a small space. GT21 Automotive Antenna Connector provides a reliable, positive lock structure with visual indication and a positive tactile click. This structure helps to provide a secure lock and prevent incomplete locking.
