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.
N Connector
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
RP-SMA Connector
RP-SMA (Reverse Polarity SMA) uses the SMA threaded coupling mechanism but with the male/female pin convention reversed — the jack has a pin and the plug has a socket. Originally standardized to prevent connection of uncertified antennas to consumer WiFi equipment, RP-SMA is now the dominant connector on commercial WiFi routers, access points, and 2.4/5 GHz antennas.
Common Applications
This N and RP-SMA cable assembly is well suited for flexible pigtails for compact modules and repeated-bend applications. The combination of reliable N and RP-SMA 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.

Frequently Asked Questions
What is RGU178 coaxial cable used for?
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.
What is the signal loss of RGU178?
At 1800 MHz, RGU178 has approximately 41 dB of loss per 100 ft (0.41 dB/ft).
What frequency range does this assembly support?
This assembly is rated DC – 6 GHz, limited by the lowest-rated component across the cable and connectors.
What is a N connector?
Type N is a threaded RF connector rated from DC to 18 GHz with a durable weatherproof design, making it the preferred interface for outdoor antenna installations, cellular base stations, and commercial wireless infrastructure. Its larger size compared to SMA allows higher power handling and the threaded coupling resists vibration, making it suitable for mobile and fixed outdoor applications.
