Red Link RG6 Full Copper Jell Filled Cable 300m Drum (RL-J3078BC)

🔧 Product Overview

While I couldn’t find the exact model RL‑J3078BC online, several specifications from similar jelly‑filled RG6 offerings provide a very close match and use typical industry standards

Construction & Materials

• Center conductor: Full copper wire (often oxygen‑free copper), approximately 1.02 mm diameter

• Dielectric: Foamed PE about 4.57 mm thick

• Inner shield: Bonded aluminum foil

• Outer shield: Braided aluminum with coverage typically ranging from 60 % to over 90 % depending on variant

• Jelly filling: Waterproof gel between dielectric and jacket for moisture protection

• Jacket: Durable PVC outer sheath, typically ~6.9 mm OD

Electrical Specs

• Impedance: ~75 Ω ±3 Ω

• Nominal velocity of propagation: ~82 %

• Structural return loss (5–3000 MHz): ≥ 20 dB

• Attenuation: For example, at 300 MHz ~11.6 dB/100 m, increasing to ~21.5 dB at 1000 MHz

Application

Designed for CATV, CCTV, satellite TV, and other RF/video systems where moisture resistance and low signal loss are required. It typically terminates with F‑type connectors on both ends

🔍 Notes on RG6 vs RG59

• RG6 has a thicker conductor, lower loss, and better high‑frequency performance compared to RG59.

• Full copper center conductors are preferred over copper‑clad steel (CCS/CCA) especially when flexibility and peak performance are required—though CCS still works due to the skin-effect at RF frequencies. Many RG6 cables use CCS to reduce cost and weight

In summary:

The Red Link RL‑J3078BC is best described as a 300 m drum of 75‑ohm, jelly‑filled RG6 coaxial cable featuring a 1.02 mm full copper core, foam PE dielectric, bonded foil + braided shielding, and robust PVC jacket. It’s optimized for video/RF signal distribution in wet or outdoor scenarios.
