Semi-Finished Coaxial Cable RG174
Thin 50 Ohm Core for GPS Antenna and RF Module Wiring
Product Overview
What This Product Is
RG174 is the small-diameter 50 ohm core used inside GPS modules, wireless antennas and test leads, where routing space matters more than power handling. The insulation diameter is about 1.52 mm and the cable runs from DC to 1 GHz at roughly 14 dB/100m at 100 MHz. Supplied without a jacket, it is bought by assembly manufacturers who add their own jacket, shielding upgrade or overmoulded connector.
Semi-Finished Coaxial Cable
Key Benefits
What It Gives Your Production Line
Fits Where Larger Coax Cannot
An insulation diameter of about 1.52 mm lets the cable route inside compact GPS and RF modules.
Shield Upgrades Without a New Cable
Standard single shield, three-layer or four-layer builds are available on the same core geometry.
Light Reels for Small Assembly Lines
Approximately 8 to 12 kg per 1000 m, so reels are easy to change on bench-scale assembly work.
Dielectric Choice for Temperature
Foamed PE for general use or FEP where the assembly sees higher temperatures.
Application Scenarios
Where It Is Used
- GPS antennas and receivers
- Wi-Fi, GSM and Bluetooth RF modules
- IoT and automotive electronics
- Laboratory and test leads
- Compact signal routing in small devices
Who It Is For
Who Buys It
- Antenna and module assemblers who overmould their own leads
- Test-equipment makers producing short patch leads
- Cable shops supplying IoT and automotive electronics
Problems It Solves
The Reasons Buyers Move To This Product
Space Inside the Enclosure
Thick coax will not bend into a compact module. A thin core solves the routing problem before jacket choice is even discussed.
Shielding Varies by Customer
One customer wants single shield, the next wants four layers. Ordering by shield build avoids stocking several finished cables.
Small Orders, Many Variants
Core supply on 500 m or 1000 m reels keeps variant stock affordable.
Technical Features
Construction And Materials
- Conductor: solid or stranded copper, or CCA

Manufacturing And Quality Control
How It Is Produced And Checked
Production runs from conductor preparation — rod drawing, annealing, stranding and surface cleaning — through foamed insulation extrusion with controlled cell size and on-line diameter monitoring, then foil wrapping and braiding to the shield specification ordered. The line stops before jacket extrusion.
Conductor Preparation
Rod drawing, annealing and surface cleaning so the insulation bonds without microvoids.
Insulation Monitoring
Insulation thickness and concentricity monitored continuously on line during extrusion.
Shield Verification
Foil overlap and braid coverage checked against the ordered shield construction.
Electrical Spot Check
Impedance and attenuation sampled against the published values for the construction.
Reel Packing
Reels wrapped in plastic film against moisture and dust, then cartoned or palletised.
Customisation Options
What Can Be Changed
- Solid or stranded conductor
- Copper or CCA conductor
- Foamed PE or FEP insulation
- Single, three-layer or four-layer shielding
- Reel length and reel material
Use Guide
Working With It On Your Line
- Support the core close to the strip point — thin coax kinks easily during hand assembly.
- Match the strip tool to the 1.52 mm insulation diameter to avoid nicking the conductor.
- Where the assembly runs hot, specify FEP insulation before production rather than reworking later.
- Keep unfinished cut lengths sealed; a bare shield picks up handling contamination quickly.

FAQ
Semi-Finished Coaxial Cable RG174 FAQ
What is the insulation diameter?
Approximately 1.52 mm for the core, which is why RG174 fits compact modules and short antenna leads.
Which shielding configurations are available?
One-layer aluminium foil plus a 96-wire braid, a three-layer build adding AL+PET tape, and a four-layer build with a second braid.
Can I get FEP insulation instead of foamed PE?
Yes. FEP is available where the assembly needs higher temperature resistance.
How heavy is a 1000 m reel?
Roughly 8 to 12 kg depending on conductor and insulation choice.
Is the cable jacketed?
No. It is supplied as conductor plus insulation and the shield you specify, ready for your own jacketing or overmoulding.
