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.

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.

RP-TNC Connector

RP-TNC (Reverse Polarity TNC) uses the TNC threaded shell with reversed pin conventions, similar to RP-SMA. It is used on some commercial WiFi access points and outdoor CPE antennas, particularly in older Cisco and Linksys equipment, and offers better vibration resistance than RP-SMA in demanding outdoor environments.

Common Applications

This F and RP-TNC cable assembly is well suited for flexible pigtails for compact modules and repeated-bend applications. The combination of reliable F and RP-TNC 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 – 2 GHz, limited by the lowest-rated component across the cable and connectors.

What is a 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.
