E11Q250 is a low smoke zero halogen PE jacketed cable for free-to-air and pay TV systems. Constructed from LSZH materials, this cable is the safe and environmentally friendly choice for your in-building network build. Available in 250m reels with meter marking, E11Q250 is suited for longer cable backbone and lateral runs where lengths are high loss with RG6. E11Q250 is a 3GHz rated low loss coaxial cable with a copper-clad steel centre conductor for durability and four shielding layers to guarantee maximum signal protection and stability.
