Triax BNC Connectors have an extra layer of insulation and a second conducting sheath. Triax connectors are used when signals require protection form noise through non-signal-carrying shielding, in applications where maximum RF shielding and minimum noise radiation are required.

Locations that host television productions will benefit from triaxial cables that run from the location of the TV truck to common camera locations throughout the building. This allows a shorter and easier workday for visiting television crews, who can simply plug into existing cables instead of having to run their own and dismantle them at the end of production.
