Specs Summary
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.
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.
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.
Common Applications
This RP-SMA 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-SMA 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.
