Fakra to SMA Automotive Radio Antenna Extension Cable

RG174/RG316 Universal Fakra Z-Code Female to SMA Female Car GPS Radio Antenna Extension Cable – High-Performance RF Connection for Automotive Systems

This versatile extension cable is engineered for seamless integration into modern vehicle communication systems, offering reliable signal transmission between GPS and radio antennas. Designed as a universal solution, it bridges the gap between standard Fakra Z-code connectors found on many OEM automotive antennas and SMA female interfaces used in aftermarket modules, ensuring compatibility across diverse vehicle models and aftermarket installations.

Constructed with either RG174 or RG316 coaxial cable options, this extension provides low insertion loss and consistent performance from DC up to 6 GHz—ideal for high-frequency applications such as satellite navigation, telematics, and wireless data transfer. The full 360° shielding minimizes electromagnetic interference (EMI), preserving signal integrity even in electrically noisy environments like modern EVs and hybrid vehicles.

The Fakra Z-Code connector features a distinctive purple key and secure clip-lock mechanism, making it resistant to accidental disconnection during vehicle operation. Meanwhile, the SMA female end offers a threaded coupling for robust mechanical stability and repeatable mating cycles—exceeding 100 engagements without degradation in electrical performance. Both connectors are built from durable materials: the Fakra housing uses color-coded plastic for quick identification, while the SMA body is crafted from brass with gold or nickel plating to resist corrosion and ensure long-term conductivity.

With customizable length options tailored to specific installation needs, this cable supports flexible routing within tight engine compartments or cabin spaces. Its lightweight, flexible design makes it easy to install without kinking or damaging internal conductors—a critical factor when extending antenna reach for improved GPS reception or FM/AM radio signal quality.

Commonly used in automotive diagnostics, fleet tracking, infotainment upgrades, and mobile broadband solutions, this adapter serves as an essential component for professionals installing GPS trackers, dashcams, OBD-II modules, or remote vehicle monitoring systems. Whether upgrading a factory-installed system or integrating third-party hardware, its plug-and-play simplicity eliminates complex wiring tasks.

Users consistently report enhanced signal strength and reduced dropouts after installation, especially in urban canyons or rural areas where weak satellite signals are common. Many appreciate how the secure locking feature prevents intermittent connections caused by vibrations or temperature fluctuations—an issue often encountered with cheaper alternatives.

For those seeking further customization, alternative configurations are available including right-angle versions for space-constrained setups, waterproof variants for outdoor exposure, and additional connector types such as Mini Fakra, SMB, MCX, HSD, or circular connectors to meet specialized requirements.

FAQs typically include questions about compatibility with different car brands (e.g., BMW, Ford, Toyota, Volkswagen), whether it supports 5G-ready devices, and if it can be used with active antennas. The answer remains yes—thanks to its broad frequency range and standardized impedance of 50 ohms, which aligns with most modern automotive RF standards.
