Description
RG-11 is a high-performance, thick-diameter coaxial cable designed for applications where signal integrity over long distances is paramount. It serves as the heavy-duty counterpart to RG-6, featuring a much larger 14 AWG center conductor that significantly reduces signal attenuation (loss). This makes it the ideal “trunk” cable for running signals from a service provider’s tap to a building or for extensive indoor runs where a standard cable would suffer too much signal drop.
The cable is built with a solid or copper-clad steel (CCS) conductor, surrounded by a thick foam polyethylene dielectric and high-efficiency shielding (typically dual or quad-layer). This robust layering provides maximum protection against electromagnetic interference (EMI) and moisture. Due to its thickness and stiffness, RG-11 is typically used for fixed installations rather than short “jumper” connections. It is compatible with specialized large-body F-type, N-type, or BNC connectors.
Key Technical Advantages
-
Ultra-Low Signal Loss: The 14 AWG conductor ensures minimal decibel (dB) loss over significantly longer distances compared to RG-6 or RG-59.
-
Superior Long-Distance Performance: Ideally suited for cable runs exceeding 150–200 feet, maintaining high signal strength for UHD digital video and high-speed data.
-
High Power Capacity: Capable of carrying higher current for remote-powered equipment, such as line amplifiers in large-scale DAS or CATV networks.
-
Heavy-Duty Shielding: Optimized to prevent ingress and egress of signals, ensuring compliance with strict RF interference standards in densely populated areas.
-
Extreme Durability: Often available with specialized jackets for direct burial (flooded) or UV-resistant outdoor use, providing a lifespan of decades.
