Tri-Shield RG6 will have 77% Braided Aluminum Shield Coverage Between 2 Layers of Aluminum Foil Shield, the 1st Foil Layer being Bonded to the Foam Dialectric. This an economical advantage to Quad Shield. Tri-Shield of the same material composition when compared Quad Shield will register the same signal Loss, with nearly the same Interference rejection qualities, at a minimum of cost increase as compared to regular 60% Braided Shield Coaxial Cable of the same material composition. The difference in flexibility as compared to Quad Shield is the mitigating factor for most installers as the chases and Wall-Plate spaces provided do not afford the luxury of the greater minimum bending radius needed when installing Quad Shield Cables.
