Percon VK 780 Silver+ Precision Digital Video Cable | 75 Ohm SDI 3G 4K UHD | Mobile Installation

Purpose of This Precision Video Cable

The Percon VK 780 Silver+ is a single 75 ohm coaxial cable for digital video. It is designed for serial digital interface transmission, high-definition television formats and 3G-SDI, and the manufacturer lists it for 4K UHD signal paths. Its flexible construction suits outside broadcast trucks, mobile units and studio camera links where cable must be moved often.

Conductor and Shield Construction

The centre conductor is silver-plated copper, which supports good high-frequency conductivity and helps keep loss down at SDI data rates. The dielectric is foamed FHDPE, and the shield is a double layer of copper-tin braid. The nominal diameter is 7.5 mm, a compact size that makes the cable easier to route through tight conduit, rigs and camera bodies.

Jacket and Mobile Use Rating

The PTC CMR jacket is built for repeated movement and bending, which is typical of mobile units, camera rigs and cable reels. The cable is listed for mobile installation, so it is chosen for flexible runs rather than fixed trunking. Check the jacket colour and rating against your production environment before committing to a long order.

Installation and Termination Guidance

Terminate the VK 780 with 75 ohm BNC connectors that match its 7.5 mm diameter and shield construction. Keep bend radii generous and avoid tight loops near the connector, since sharp bends can disturb the impedance. Test each run after installation, because SDI links depend on clean terminations as much as on the cable itself.

Ordering and Application Advice

Choose the VK 780 Silver+ for mobile and camera runs that carry 3G-SDI or 4K UHD signals. For a heavier build with a larger conductor, see the VK 880 Silver+. Cable is quoted by length and colour, so send the route length and jacket colour with your enquiry, along with the connector type you plan to use.
