About This Assembly

RG174 Cable

RG-174 is an ultra-thin, highly flexible 50-ohm coaxial cable with a 0.100" outer diameter — one of the smallest coax types available. Its stranded center conductor and single-braid shield make it ideal for tight internal wiring where space is at a premium. Typical uses include GPS antenna pigtails, WiFi module connections, and short adapter leads inside enclosures.

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.

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 BNC and RP-TNC cable assembly is well suited for GPS and WiFi module pigtails, short flexible adapter leads, and internal device wiring. The combination of reliable BNC 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 RG174 coaxial cable used for?

RG-174 is an ultra-thin, highly flexible 50-ohm coaxial cable with a 0.100" outer diameter — one of the smallest coax types available. Its stranded center conductor and single-braid shield make it ideal for tight internal wiring where space is at a premium. Typical uses include GPS antenna pigtails, WiFi module connections, and short adapter leads inside enclosures.

What is the signal loss of RG174?

At 1800 MHz, RG174 has approximately 32 dB of loss per 100 ft (0.32 dB/ft).

What frequency range does this assembly support?

This assembly is rated DC – 3 GHz, limited by the lowest-rated component across the cable and connectors.

What is a 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.
