HIGH-DEFINITION 75 Ohm Coaxial VIDEO CABLE

The 75-ohm coaxial cable GF7-449D is an identical alternative to the commonly used V73263 cable, offering equivalent electrical performance, size, weight, connector compatibility, and application versatility. It features a double-shielded cable with a helically-wrapped silver-plated copper strip and tin-plated copper braid, providing over 100% shielding coverage. The GF7-449D is recommended for SMPTE 259M and is also suitable for SMPTE 292, SMPTE 424, and 12G-SDI video applications.
