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 Series provides independent seizing of the cable's center and outer
conductors during the installation process, guaranteeing proper cable retention.
Uniquely, the GRS design compensates for potential tolerance mismatches between
the cable and connector.
The connector configuration allows a full view of the center conductor entering the center
conductor seizing mechanism, eliminating the "blind entry" associated with 2-piece
connector installation.
Cable "pullback" is minimized, preventing cable deformation. GRS extension
connectors, used extensively in system upgrades, incorporate a one-piece continuous
pin, providing excellent long-term performance.

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.
