RG 59B/U

The Alpha Wire RG 59B/U cable has been precisely designed to broadcast video transmission at the highest quality whilst achieving low capacitance, high velocities of propagation and tight tolerances for maxiumum signal intergrity.
The cable has a single strand solid 23 AWG copper-coated steel centre core surrounded by polyethylene insulation and a black PVC anti-contamination sleeve. The component can remain operational at temperatures -20°C or more and is an approved component by MIL-C 17D. It is availiable to purchase at reels of 30 and 305 metres.
