BNC-to-RCA Adapter for 75 ohm Signal Chains
The Monoprice 104121 adapts a male BNC twist-lock connector to a female RCA jack, letting you integrate legacy coaxial feeds into consumer audio-video equipment. It is built for installers and hobbyists who need a reliable gender change without signal degradation across 75 ohm paths.
Gold-Plated Contacts and Twist-Lock Security
Solid gold-plated conductors resist oxidation while maintaining low-loss transfer for composite video or SPDIF audio. The BNC side uses a twist-lock mechanism that prevents accidental disconnects caused by cable weight or rack vibration, a practical advantage over friction-fit alternatives in permanent installations.
Lifetime Warranty Backing from Monoprice
The adapter ships as a single passive component with no additional cables, tools or software included. Monoprice covers the unit under a lifetime warranty, so a failed connector can be replaced without sourcing a new part, reducing long-term maintenance cost for fixed wiring projects.

Questions about this item
Does the 75 ohm rating limit the bandwidth of the BNC to RCA connection?
The adapter is rated for 75 ohm signals, which matches standard video and digital audio coaxial cables, so it does not introduce an impedance mismatch that would cap usable bandwidth.
What clearance does the twist-lock BNC male end need behind a panel or rack?
The male BNC twist-lock requires enough depth for the bayonet collar to rotate and lock, typically a few centimetres behind the panel cut-out for finger access.
How do you attach the BNC male twist-lock to a female BNC jack without damaging the pin?
Align the centre pin, push the connector straight in, then twist the knurled collar clockwise until it clicks; forcing it at an angle bends the centre pin.
