FAKRA Antenna Cables | Z and C Code, Female to Male & Female to Female, 6–20 ft
FAKRA RF cables for GPS, cellular and telematics installs.
SMB-based FAKRA antenna extensions and jumpers on RG174 50 Ω coax, rated to 4 GHz, with molded, keyed FAKRA connectors. Z code (neutral, mates with every keyed color) in female-to-male 6, 10, 15 and 20 ft for extending a roof antenna to a dash unit or telematics gateway; C code (blue) female-to-female 6 and 10 ft for GPS and SDARS modules. Fleet upfitters, RV and van builders, and automotive OEMs at volume pricing; same-day shipping from Oxnard, CA.
Which code
| Code | Color | Use |
|---|---|---|
| Z | Water blue / neutral | Universal: mates with any keyed FAKRA, so one extension serves GPS, GSM, LTE and DAB |
| C | Blue | GPS, GNSS and satellite radio (SDARS) |
| D | Bordeaux | GSM and LTE cellular (custom lengths on request) |
| A | Black | Radio and DAB (custom on request) |
Female-to-male is an extension (plugs into the existing cable and the module); female-to-female joins two male tails or a module to an antenna pigtail.

FAKRA Cable FAQ
1. What is a FAKRA cable assembly?
FAKRA is an automotive-grade RF interconnect system based on SMB geometry, keyed and color-coded to prevent cross-mating while maintaining 50 Ω impedance.
2. Why choose Conversions Tech High-Performance FAKRA cables?
Every assembly is continuity-checked and vector-network-analyzed to 4 GHz (VSWR < 1.3), ensuring rock-solid GNSS, LTE, satellite-radio and ADAS signals.
3. What frequencies and impedance are supported?
Rated DC – 4 GHz with a nominal 50 Ω characteristic impedance; low-loss builds provide headroom up to 6 GHz.
4. Which FAKRA codes & colors do you stock?
Blue B (GPS), Bordeaux-violet C (cellular), Green E (satellite radio), Brown F (AM/FM) and universal Aqua Z.
5. What’s the difference between code “Z” and “C”?
Code Z is un-keyed (“universal”) for lab or retrofit work; Code C has a dedicated mechanical key and Bordeaux-violet jacket for cellular telematics modules.
6. Which coax types do you use?
Standard builds use RG-174 LL for flexibility; premium low-loss options (RTK031 / TFC-302 LL) cut insertion loss by ~40 %.
7. Are your cables backwards-compatible with SMB?
The RF pin mates electrically with SMB, but the keyed plastic housing blocks direct connection. Use our FAKRA-to-SMB adapters when cross-connecting lab gear.
8. Typical applications?
GNSS antennas, LTE/5G telematics, satellite radio, HD-radio, Wi-Fi, rear-view cameras, LiDAR timing and V2X DSRC links.
9. Are Conversions Tech FAKRA assemblies automotive-rated?
Yes—they meet ISO 20860-1 electrical and SAE USCAR-17 mechanical-pull (≥ 90 N) and operate from -40 °C – +105 °C.
10. What connector retention does the latch provide?
The secondary lock tab withstands > 100 N axial force; a violet eject-key tool releases it in tight dash cavities.
11. Are these cables RoHS / REACH compliant?
Absolutely—every lot is tested < 0.1 % Pb/Cd/Hg; compliance declarations ship with your invoice.
12. Do you offer custom lengths, jackets or labeling?
Yes—any length from 4 in (10 cm) to 50 ft (15 m), with optional heat-shrink ID, over-molding or braided PET sleeve (MOQ 100 pieces).
13. What’s the minimum bend radius?
8 × OD (≈ 20 mm for RG-174); frequent flex at 25 mm radius passes 2 000-cycle vibration per USCAR-2.
14. How much loss over 15 ft?
≈ 1.5 dB @ 2 GHz on RG-174; ≈ 0.7 dB on low-loss RTK031—ideal for runs from roof antenna to telematics ECU.
15. Best routing practice to avoid EMI?
Keep ≥ 100 mm from ignition coils or DC/DC converters, cross power cables at 90 °, and bond shields to chassis ground.
16. Do you sell plug-and-play extension cables?
Yes—6 ft, 10 ft and 15 ft Z-to-Z or C-to-C extensions ship from stock.
17. Outdoor or marine use?
Specify our UV-stabilized jacket and nickel-plated housings; IP67 caps are available for exposed antennas.
18. MOQ for private-label?
250 units with laser-etched logo and custom bag header.
19. Warranty & returns?
Lifetime signal-integrity warranty plus a 30-day no-quibble return policy.
20. How do I safely disconnect a FAKRA plug?
Press the side latch until it clicks, then pull straight—avoid twisting to protect the keyed shell.
21. FAKRA vs. SMA—which to pick?
FAKRA adds keyed plastic housing, higher pull-force, color coding and vibration resistance; SMA is lighter but lacks automotive safety locking.
22. Certifications carried?
ISO 9001 and IATF 16949 production; cable lots are serialized and traceable to SPC data.
23. Do they work for Wi-Fi 6E / 7 back-haul?
Yes—low-loss assemblies keep IL < 2 dB across 5.925–7.125 GHz, making them 6 GHz-ready for in-car access points.
