Semi-Finished Coaxial Cable – RG6 CU/64/AL (75Ω)
1. Construction Details
| Component | Specification |
|---|---|
| Inner Conductor: | Solid Pure Copper (CU), Ø ~1.00 mm – excellent electrical conductivity |
| Dielectric: | Foamed Polyethylene (PE), Ø ~4.60 mm – low dielectric loss, stable 75Ω impedance |
| Shield (Braid): | 64 strands of bare Aluminum (AL) – ~65–70% coverage, moderate EMI protection |
| Outer Jacket: | Not included – jacket to be added during OEM or custom extrusion (PVC, PE, LSZH, CPR, etc.) |
2. Typical Dimensions
