Semi-Finished Coaxial Cable –RG11 CU/96/AL
1. Cable Structure (Without Outer Jacket)
| Layer | Material | Approximate Diameter |
|---|---|---|
| Inner Conductor | Solid Copper (CU), Ø 1.63 mm | 14 AWG |
| Dielectric | Foamed Polyethylene (FPE), gas-injected | ~7.24 mm |
| First Shield (Tape) | Bonded Aluminum-Polyester Foil (100%) | — |
| Second Shield (Braid) | 96-strand Aluminum (AL), ~60–65% coverage | — |
| Outer Jacket | Not included (semi-finished format) | — |
Outer Diameter (semi-finished core): ~7.8–8.0 mm
Outer Diameter (with jacket): ~10.2–10.5 mm (varies by jacket type)
2. Electrical Performance
| Parameter | Typical Value |
|---|---|
| Characteristic Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (FPE insulation) |
| Attenuation @ 100 MHz | ~5.0–5.2 dB/100m |
| Shielding Effectiveness | High (due to dense AL braid + foil) |
| DC Resistance | Very low (solid copper core) |
3. Key Features
High Signal Integrity: Solid copper inner conductor offers excellent low-loss performance across long distances
Enhanced Shielding: 96-wire aluminum braid + full foil coverage provides strong EMI protection
OEM-Ready Core: Can be finished with PE, PVC, LSZH, UV-resistant, or dual-layer jackets depending on application
Flexible Integration: Ideal for hybrid cables, bundled assemblies, and outdoor/indoor jacket customization
4. Typical Applications
Professional-grade CATV trunk and feeder networks
Long-range broadband transmission lines
Satellite dish and headend signal distribution
Export cable cores for custom finishing or private-label production
Environments with moderate to high electromagnetic interference
5. Considerations
Aluminum braid is lighter and less durable than copper or CCA braids
Requires jacket application before use in the field
Not suitable for direct burial or UV exposure without jacket finishing
