Specs Summary
About This Assembly
RGU178 Cable
RGU-178 is an ultra-flexible variant of the RG-178 coaxial cable, retaining the 1.75mm form factor while featuring a stranded center conductor and flexible jacket for repeated bending. It excels in applications requiring both a small footprint and mechanical durability, such as wearable devices, rotating joints, and flexible test leads.
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.
F Connector
The F connector is a low-cost threaded coaxial connector used almost exclusively in cable TV, satellite, and over-the-air broadcast applications. It uses the center conductor of RG-6 or RG-59 cable as the pin, which simplifies termination and reduces cost. F connectors are found on cable modems, satellite receivers, TV tuners, and distribution amplifiers.
Common Applications
This BNC and F cable assembly is well suited for flexible pigtails for compact modules and repeated-bend applications. The combination of reliable BNC and F 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.
