Flexible, low-loss, precision coax for SPDIF or other 75S digital audio applications that require flexibility in a nonpermanent installation application. Unlike conventional coax cable, utilize a stranded center conductor, double-braid shield, and ultra-flexible PVC jacket for excellent flexibility and flex-life. Feature low-loss, crush resistant, gas-injection foam dielectric used in Gepco's High Definition video coax series. This dielectric process and compound reduces the occurrence of cable induced bit-rate errors and jitter in the data stream through precision dimensions, uniform cell structure, and minimized internal reflections and impedance mismatches.
