E11QF250 is an RG11 75 Ohm flooded quad-shield coaxial cable for free-to-air and pay TV systems. It’s approved for both Foxtel satellite and Telstra cable networks. With an integrated flooding compound, E11QF250 is well suited for use in underground cable links and all outdoor exposed usage to prevent any moisture ingress from degrading your network. Available in 250m reels with meter marking, E11QF250 is suited for longer cable backbone runs where lengths are high loss with RG6. E11QF250 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.
