Semi-Finished Coaxial Cable – RG11 CCS/48/AL
1. Cable Construction (No Jacket)
| Layer | Material | Approx. Diameter |
|---|---|---|
| Inner Conductor | Copper-Clad Steel (CCS), Ø 1.63 mm | 1.63 mm (14 AWG) |
| Dielectric | Foamed Polyethylene (FPE), physical foam | ~7.24 mm |
| Shield 1 (Foil) | Bonded Aluminum-Polyester Foil (100%) | — |
| Shield 2 (Braid) | 48 wires Aluminum (AL), ~30–35% coverage | — |
| Outer Jacket | Not included (semi-finished) | — |
Outer Diameter (core only): ~7.8 mm
Outer Diameter (after jacket): ~10.2 mm (varies by jacket type)
2. Electrical & Performance Characteristics
| Parameter | Typical Value |
|---|---|
| Impedance | 75 ohms |
| Capacitance | ~53 pF/m |
| Velocity of Propagation | ~85% (FPE dielectric) |
| Attenuation @ 100 MHz | ~5.8–6.0 dB/100m |
| Shielding Effectiveness | Basic (due to lower braid density) |
3. Key Features
CCS Conductor: Provides excellent mechanical strength; ideal for tension and pull resistance
48-wire AL Braid: Low-cost shielding suitable for basic EMI protection in low-noise environments
Jacket-Free (Semi-Finished): Enables flexible jacket selection (PVC, PE, LSZH, etc.)
Ideal for mass production, export customization, or OEM value-line products
4. Application Scenarios
Entry-level CATV and satellite distribution
Cost-sensitive infrastructure where shielding demand is low
OEM finishing with flame-retardant, UV-resistant, or armored jackets
Bundled coaxial cables for multi-core applications
5. Considerations
Highest attenuation among RG11 types using CCS/AL 48-braid
Not recommended for high-interference or professional-grade RF environments
Excellent for price-driven markets or shorter-length indoor runs
6. Comparison Snapshot
| Type | Conductor | Braid Type | Shield Coverage | Attenuation @100 MHz | Cost |
|---|---|---|---|---|---|
| CCS/48/AL | CCS | AL x 48 | ~30–35% | ~5.8–6.0 dB/100m | 💲 Lowest |
| CCS/64/AL | CCS | AL x 64 | ~35–40% | ~5.6 dB/100m | Low |
| CCS/96/AL | CCS | AL x 96 | ~55–65% | ~5.2 dB/100m | Medium |
| CU/64/CCA | Copper | CCA x 64 | ~40–45% | ~5.0 dB/100m | Higher |
