Did you know coaxial cables were invented by English scientist Oliver Heaviside in 1880? The original technology may be almost 140 years old but our cables are brand spanking new. Made only with the highest quality materials, HiBoost has your hookup needs covered. Strong, durable construction for long lasting use. Used for radio frequency (RF) signal transmission, this insulated coaxial cable works perfectly with all of our boosters. We typically recommend this length most with the Home 4K, or our Home 10K, especially in cases where you need additional length for more isolation for the booster or if you need to attach additional antennae to get the best coverage in your home or office.
