RG 11 cable: A thick, low-loss coaxial cable with a 75 Ω impedance, designed for high-frequency signal transmission over longer distances than smaller cables like RG 6. Thanks to its larger diameter and enhanced shielding, RG 11 offers lower attenuation, making it ideal for main trunk lines in cable TV systems, broadband internet, satellite feeds, and large building or campus installations. Its durable construction ensures reliable signal quality and reduced interference, even in demanding outdoor and high-frequency environments.
