Percon VK 780 Silver+ UNG-4K Black - 500m
Silver+ Coaxial video cable for digital applications. Can carry serial data interface (SDI) and high definition television formats (HDTV) according to SMPTE 259M (270Mbps), ITU-R BT.601 (composite PAL at 177Mbps) ,SMPTE 292M (1,5Gbps) ,SMPTE 424M (Prog. Scan. HDTV/3G-SDI) , SMPTE ST2081 (QFHD) & SMPTE ST2082 (UHD-1). It is also used for analogue critical circuits. Perfect for installations in environments with interferences (power cables, transformers, electronic light controls (dimmers) or mobile phones) due to the high depth of penetration, the low transference impedance and the minimum DC resistance of its double shield (tinned copper braid 95%) that increases the reflections of the electric fields as well as the absorption of the magnetic fields, offering an attenuation over 90 dB before high, medium and low-frequency electromagnetic signals.
Available in reel size of 500m.
