cable Standard 75 Ohm Plasma Grade video coaxial cable Van Damme Standard 75 Ohm Plasma Grade Video Coax is a high resolution cable designed for use with analogue video signals. Precision performance is combined with exibility usually only found in microphone cables resulting in an excellent video cable for dynamic use in the broadcast, video and presentation markets. Applications Analogue video transmission up to 100 metres Suitable for SP Dif digital audio and word clock Application notes Can be used with serial digital video transmissions up to 138 metres Uses RG59 type crimp connectors Colour coding suitable for RGBHV, RGBS, YUV and other video formats Ultra pure oxygen free copper for outstanding sonic integrity Transmission length guidelines These transmission lengths have been calculated throughout to a maximum attenuation of -30dB at the frequency corresponding to half of the actual signal data rate for SMPTE 259. SMPTE and others advise that 90% of this cable length introduces an appropriate safety factor - this has been taken into account in the chart below.
