Overview of CABRG58CU Coax Cable
CABRG58CU is a 50 Ohm coaxial cable with a nominal 5mm outer diameter, commonly used as an RG58-style flexible copper coax for radio-frequency, antenna feeder and laboratory connections. The black PVC jacket provides mechanical protection for indoor and short outdoor runs. This page helps South African makers, technicians and procurement teams assess suitability, compare specs, and plan purchases with local stock and pickup options at Communica.
Key Specifications
| Parameter | Typical Value | Notes |
|---|---|---|
| Characteristic impedance | 50 Ohm | Standard for RF test, antennas, transceivers |
| Outer diameter | ~5 mm | Flexible; easy routing in enclosures |
| Center conductor | Copper (solid/stranded variants) | Check datasheet for strand count and plating |
| Jacket | Black PVC | Indoor and short-term outdoor use; UV and oil resistance vary |
| Frequency range | DC to several hundred MHz (application dependent) | Attenuation increases with frequency; check loss spec for your band |
Primary keyword: network-and-communication-cable-cabrg58cu-coax-cable-50r-5mm-black appears throughout this page to help you find product information and stock availability for CABRG58CU coax cable in South Africa.
Where it's typically used
- HF/VHF/UHF antenna leads for handhelds and small base stations (short runs).
- RF test setups, lab benches and temporary measurement feeds.
- Interconnecting RF modules, transceivers and patch panels where 50 Ohm is required.
Consideration: For long outdoor antenna feeders, low-loss types (e.g., LMR-400) perform better. CABRG58CU is practical for short to medium runs inside buildings, test labs and prototyping rigs. See comparing coax cables for network communication for guidance when choosing cable for longer runs.

Selection & Compatibility Guidance
When choosing CABRG58CU, check connector compatibility (BNC, TNC, SMA, N-type). The cable's 5mm outer diameter is closest to RG58-type crimp or solder sleeve installations. If you need to fit an SMA connector, verify inner dielectric and conductor dimensions or choose factory-assembled leads to ensure reliable VSWR and low insertion loss.
Practical comparison
| Cable | Use Case | Typical advantage |
|---|---|---|
| CABRG58CU (50 Ohm, 5mm) | Short antenna leads, lab patching | Flexible, low-cost, easy to terminate |
| LMR-400 (50 Ohm, ~10mm) | Long outdoor feeders, low-loss links | Lower attenuation, better shielding |
| RG174 (50 Ohm, ~2.8mm) | Very short jumper leads, high flex spots | Very flexible but higher loss per metre |
Installation tips & examples
For best RF performance: keep cable runs as short and straight as practical, avoid tight bends (minimum bend radius ~4-6x cable diameter), and secure with soft clips to prevent microphonics. When terminating with BNC or SMA connectors, use the correct crimp die or solder sleeve; improper terminations degrade match and raise insertion loss. See how to install CABRG58CU coax cable for step-by-step guidance.
Accessories and bundles
- Pre-assembled pigtails (CABRG58CU with BNC/SMA) for plug-and-play use.
- Connector kits: BNC crimp/solder, SMA crimp, heatshrink and Ferrules.
- Test equipment: VSWR meters, spectrum analysers, directional couplers for alignment and verification.
