About This Assembly
Specs Summary
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.
Misc Connector
This connector type includes specialized or application-specific RF connectors designed for particular equipment or industries. These may include 2.4mm, 2.92mm (K), 1.85mm (V), SMP, SSMP, or proprietary interface types used in precision microwave measurement, defense electronics, and specialized RF subsystems.
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 F and Misc cable assembly is well suited for flexible pigtails for compact modules and repeated-bend applications. The combination of reliable F and Misc 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.
