About This Assembly
Specs Summary
RG58 Cable
RG-58 is a classic flexible 50-ohm coaxial cable with a 0.195" outer diameter, offering an excellent balance of flexibility and performance at a low cost. Its braided shield provides good EMI rejection and its thin profile makes it easy to route through tight spaces. Common applications include amateur radio, CB radio, networking equipment connections, and general-purpose RF jumpers up to 25 feet.
Fakra Connector
Fakra is a family of color-coded RF connectors standardized for the automotive industry, designed to withstand the vibration, temperature extremes, and EMI environment of vehicles. Each color code denotes a specific application — GPS, DAB radio, SDARS satellite radio, cellular, or WiFi — preventing incorrect connections during vehicle assembly.
SMB Connector
SMB (SubMiniature version B) is a snap-on RF connector with a simple push-on coupling rated to 4 GHz. Its ease of mating and small footprint make it popular in telecommunications equipment, set-top boxes, GPS timing receivers, and instrumentation where a secure but easily disconnected interface is needed.
Common Applications
This Fakra and SMB cable assembly is well suited for amateur radio, CB radio, and general-purpose RF patch cables. The combination of reliable Fakra and SMB 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.
