The V78209 75 ohm coaxial cable offers low VSWR and attenuation characteristics for high-definition digital video. The construction of V78209 includes a silver-plated copper center conductor, a foamed fluoropolymer dielectric and it is double-shielded with a braid of tin-plated copper and an aluminized 100% coverage wrapper. Because of the critical effect of impedance-matched terminations, a comprehensive family of 75-ohm connectors are available.
