About This Assembly

RG400 Cable

RG-400 is a double-shielded, silver-plated PTFE coaxial cable built to MIL-C-17 specifications with a 0.195" outer diameter. Its construction mirrors RG-142 but with two braid shields for even greater shielding effectiveness. The standard cable for military and avionics applications requiring certified materials and traceable performance.

BNC Connector

BNC (Bayonet Neill–Concelman) is a quick-connect RF connector featuring a bayonet locking mechanism for fast mating and unmating, rated from DC to 4 GHz. Its ease of use makes it standard in test and measurement equipment, video distribution, two-way radio accessories, and laboratory bench setups where cables are frequently connected and disconnected.

MCX Connector

MCX (Micro Coaxial) is a snap-on RF connector approximately 30% smaller than SMB, designed for compact equipment requiring frequent connections in a small footprint. Rated to 6 GHz, MCX is commonly used in GPS receivers, automotive telematics modules, handheld communication devices, and compact measurement instruments.

Common Applications

This BNC and MCX cable assembly is well suited for military-spec RF interconnects and avionics signal routing. The combination of reliable BNC and MCX connectors and custom-cut cable length makes it a practical choice for both field installations and bench setups. Every assembly is hand-terminated, continuity tested, and ships free within the USA.
