Specs Summary
About This Assembly
RG178 Cable
RG-178 is an extremely thin 50-ohm coaxial cable measuring just 1.75mm in diameter, designed for space-constrained RF assemblies. Its PTFE dielectric and silver-plated conductors deliver reliable performance from DC up to several GHz. Commonly used for internal wiring in test equipment, medical devices, and cellular module pigtails.
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 ultra-compact internal wiring in test equipment and small wireless modules. 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.
