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.

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.

SMA Connector

SMA (SubMiniature version A) is the most widely used RF connector in the industry, offering a threaded interface that provides a secure, low-reflection connection from DC to 18 GHz. Its compact size, 50-ohm impedance, and broad frequency range make it the default choice for WiFi equipment, software-defined radios, cellular antennas, GPS receivers, and RF test instruments.

Common Applications

This F and SMA cable assembly is well suited for GPS and WiFi module pigtails, short flexible adapter leads, and internal device wiring. The combination of reliable F and SMA 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 – 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.
