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.

UHF Connector

The UHF connector (also known as PL-259 male / SO-239 female) is a large, low-cost RF connector designed in the 1930s for HF and VHF frequencies. Despite its name, its practical usable range is below 300 MHz due to its non-constant impedance design. It remains extremely popular in amateur radio (HF through VHF), CB radio, and marine radio applications.

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