Product Description
Extra-Flexible RG59 Cable for Professional SDI Video
The AV-Cables Belden 1505F Extra Flexible RG59 HD-SDI BNC cable is designed for professional broadcast, video production and commercial AV applications where easier routing and repeated cable handling are important.
Built using genuine Belden 1505F precision 75-ohm coax and professional Kings true 75-ohm BNC connectors, this flexible cable supports SD-SDI, HD-SDI, 3G-SDI and 6G-SDI video systems.
The stranded 20 AWG copper conductor provides greater flexibility than traditional solid-conductor RG59 cable, making 1505F an excellent choice for cameras, equipment racks, carts, fly packs, production trucks and live-production environments.
Why Choose Belden 1505F?
Belden 1505F provides the signal integrity of professional RG59 video coax with a stranded center conductor engineered for increased flexibility. It is particularly useful where cables are frequently moved, coiled, transported or routed around production equipment.
