Low Loss SDI and HDTV Video Cables Belden 1694A is an excellent low loss, 75 ohm coaxial cable, with

superb bandwidth, low capacitance and double shielding (one foil

screen, one tinned copper braid). Belden 1694A is useful in a wide

variety of applications, from low-frequency analogue audio through

the most demanding, high frequency, high-bandwidth uses like longer

runs of SDI and HDTV. Its specification compares favourably with any

competing product and exceeds most by virtue of its certified sweeptesting to 4.5 GHZ.
