The industry-leading GRS™ 3-piece trunk & distribution connector series is designed for optimal performance in high bandwidth, two-way and digital communication systems. The GRS provides independent seizing of the cable’s center conductor and outer conductors during the installation process, guaranteeing proper cable retention.
Materials and Construction of Connector Components: ASTM 6000 aluminum alloy with gold chromate conversion coating for excellent corrosion resistance and a dry film lubricant to prevent thread galling. Contact pins and support sleeves are brass with bright acid tin plating providing excellent RF conductivity. O-rings are ultraviolet and ozone resistant EPDM for maximum durability.
GRS extension connectors, used extensively in system upgrades, incorporate a one-piece continuous pin, providing excellent long-term performance.
