Q: Is RG-174 compatible with automotive FAKRA connectors?

Yes, RG-174 (both solid PE and low-loss foam PE variants) is the primary 2.8 mm cable size used with standard crimp FAKRA and Mini-FAKRA connectors in vehicle telematics. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

Q: How small can RG-174 be bent inside an instrument enclosure?

With its 2.79 mm outer diameter and 7-strand 26 AWG center conductor, RG-174 supports a minimum static bend radius of 12 mm (4 × D) without impedance discontinuity. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

RG-174 (RG-174/U and RG-174A/U, MIL-DTL-17/119) is a miniature, highly flexible 50 Ω coaxial cable with a 2.79 mm outer diameter for GNSS/GPS active antennas, cellular/IoT pigtails, automotive FAKRA harnesses, and test instrument leads up to 1000 MHz.

FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

When should RG-174A/U (pure copper conductor) be chosen over standard RG-174/U (CCS)?

Standard RG-174/U uses a 40 % copper-clad steel (CCS) center conductor (~317 Ω/km DC resistance) for high tensile strength at RF, whereas RG-174A/U uses pure annealed copper (~140 Ω/km DC resistance) to minimize DC voltage drop when feeding 3.3 V or 5 V DC phantom power to active GNSS/GPS LNA antennas.

What is the practical upper frequency limit of RG-174?

RG-174 is ideal from DC to 1000 MHz (including VHF/UHF, 433/868/915 MHz ISM, and short < 3 m 1575 MHz GPS L1 pigtails); for higher frequencies up to 3–6 GHz or temperatures above +80 °C, specify PTFE-insulated RG-316. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.

Is RG-174 compatible with automotive FAKRA connectors?

Yes, RG-174 (both solid PE and low-loss foam PE variants) is the primary 2.8 mm cable size used with standard crimp FAKRA and Mini-FAKRA connectors in vehicle telematics. Each production reel undergoes sweep-frequency impedance and return-loss verification, dielectric spark testing, and dimensional inspection before dispatch with an EN 10204 3.1 test certificate.
