  75Ω Coax: Permanent Installation  
         
   
  Low-loss, low-jitter, precision impedance coax for Word Clock, AES3id, SPDIF, or multiplexed digital audio formats. The same as Gepco's HD video series, these coaxial cables utilize Gepco's 3GHz gas-injected, low k constant dielectric and a precision-drawn, solid copper conductor. For comprehensive broadband shielding, a dual shield, foil and braid, is used to protect against both highfrequency RF and EMI noise and interference. All electrical and mechanical characteristics are manufactured to precision tolerances and specifications to minimize attenuation, internal reflections, and impedance mismatches. As a result, pulse rounding, bit-errors, and jitter from the cable interconnection are minimized.
