Semi-Finished Coaxial Cable RG11
Low Loss 75 Ohm Trunk Core for Long Distance Distribution
Product Overview
What This Product Is
RG11 is the large-conductor member of the 75 ohm family, and in semi-finished form it gives cable makers a trunk-grade core without the foaming line. Loss is about 4.8 dB/100m at 100 MHz and conductor DC resistance around 3.5 ohms per 100 m, which is why it goes into long CATV runs and FTTH hybrid builds where an RG6 drop would not reach. The jacket is left off so the same core can be finished for indoor conduit, outdoor aerial or direct-burial duty.

Key Benefits
What It Gives Your Production Line
Reach Where RG6 Runs Out
Lower attenuation and lower conductor resistance keep signal usable over long trunk runs and tall building risers.
One Core for Indoor and Outdoor Finishes
Choose PVC, LSZH or PE at the jacketing stage instead of stocking separate finished cables.
Heavy Reels Packed for Container Loading
Heavy-duty plastic, wooden or ABS reels, film wrapped, with carton or pallet options for bulk shipment.
Shield Depth to Match the Plant
Standard, tri-shield or quad-shield, with 40 to 95 percent braid coverage on the first two builds.
Application Scenarios
Where It Is Used
- Long-distance CATV signal distribution
- Digital TV and satellite DVB-S/S2 systems
- Broadband and trunk-line RF systems
- Fibre-to-the-home hybrid cabling
- High-frequency data and video in commercial buildings
Who It Is For
Who Buys It
- CATV cable manufacturers supplying network operators
- Plants building trunk and riser cable for large projects
- Brands that need RG11 in their catalogue without a dedicated production line
Problems It Solves
The Reasons Buyers Move To This Product
Large Dielectric Is Slow to Run
A big foamed dielectric ties up an extruder for a long time. Buying the core keeps that line free for higher-turn products.
Trunk Cable Is Ordered in Bursts
Project-driven RG11 demand is hard to schedule. Core stock lets you jacket to order in days rather than weeks.
Different Jackets per Project
Aerial, duct and in-building jobs all want different jackets on the same electrical core.

Manufacturing And Quality Control
How It Is Produced And Checked
Production runs from conductor preparation — rod drawing, annealing, stranding and surface cleaning — through foamed insulation extrusion with controlled cell size and on-line diameter monitoring, then foil wrapping and braiding to the shield specification ordered. The line stops before jacket extrusion.
Conductor Preparation
Rod drawing, annealing and surface cleaning so the insulation bonds without microvoids.
Insulation Monitoring
Insulation thickness and concentricity monitored continuously on line during extrusion.
Shield Verification
Foil overlap and braid coverage checked against the ordered shield construction.
Electrical Spot Check
Impedance and attenuation sampled against the published values for the construction.
Reel Packing
Reels wrapped in plastic film against moisture and dust, then cartoned or palletised.
Customisation Options
What Can Be Changed
- Conductor grade BC, CCA, CCS or CCAM
- Standard, tri-shield or quad-shield
- Braid coverage 40 to 95 percent
- Reel length and reel material
- Carton or wooden pallet bulk packing
Use Guide
Working With It On Your Line
- Use a powered pay-off — RG11 reels are heavy and free-spinning stands can snap the core.
- Keep bend radius generous during jacketing; a large foamed dielectric deforms more easily than RG6.
- Match haul-off tension to reel weight, which changes noticeably between a full and a nearly empty reel.
- Record reel numbers against finished drums so trunk cable stays traceable for project handover.

FAQ
Semi-Finished Coaxial Cable RG11 FAQ
How much lower is RG11 loss compared with RG6?
About 4.8 dB/100m at 100 MHz against roughly 6.5 dB/100m for RG6, with conductor DC resistance around 3.5 ohms per 100 m.
Can RG11 cores be finished for direct burial?
Yes. The core is supplied unjacketed, so a PE jacket with your own water-blocking elements can be applied on your line.
What reel weight should we plan for?
Approximately 24 to 30 kg per 500 m, depending on conductor and shield type.
Is quad-shield available on RG11?
Yes, as a foil-plus-braid construction repeated twice, alongside standard and tri-shield builds.
How is bulk shipment packed?
Reels are wrapped in plastic film, then packed in carton boxes or on wooden pallets for container loading.
