Trunk Cable and Connectors
The trunk cable (catalog number 1786-RG6) is a low-loss, RG-6 quad-shield
coaxial cable. It’s the bus or central part of the coax media system. The trunk
cable is composed of multiple sections of cable.
You can use several types of special-use cables, such as flexible (1786-RG6F),
direct burial, or plenum rated, that are available from third-party vendors.
Choose the cable type based on the application and or environment where
your system is being installed.
A cable connector (catalog number 1786-BNC) attaches coax trunk-cable
sections to a tap’s BNC connector. Standard BNC connectors twist and lock
onto the cable. However, these connectors are not designed for rugged
conditions, such as vibration, water, and so forth. Use IP67 media connectors
(catalog number 1786-TNC) that have screw threads for harsh
environmental conditions.
