RG59U CCTV Outdoor 4K Coaxial Cable


RG59U outdoor 4K coaxial cable is commonly used in closed-circuit television (CCTV) systems to transmit high-resolution video signals over long distances. The “U” in the name indicates that the cable has a solid copper center conductor, which provides better signal transmission than a stranded conductor. The 4k coaxial cable is designed for outdoor use, with a weather-resistant jacket that protects it from moisture and other environmental hazards.

This CCTV outdoor coaxial cable is capable of transmitting 4K Ultra HD video signals over distances of up to 300 meters (1000 feet), making it well-suited for use in large buildings, campuses, or other areas where long cable runs are necessary.
