75 ohm cables designed specifically for digital video applications. L-4CFB is RG59 type, L-5CFB is RG6 type. Semi-matt non-reflective PVC jacket. Double screened, foil plus braid. L-5CFB handle signals from DC to 3GHz, thus covering uncompressed HDTV signals right up to 3Gbits/sec (SMPTE424M). Blue jacket is designed to work with chroma-key. A range of colours is available to special order, allow 4 weeks for delivery (supplied as full reels of 200 metres only).
Note: See suitable connectors for these cables in the drop-down lists below the full cable specification.
