Ultra-stable, precision 75 Ohm, low-loss gas-injected dielectric RG-59 video coax with high-bandwidth BNC connectors for Word Clock distribution in critical audio applications. These assemblies use 3GHz High-definition coax that feature Gepco's proprietary gas-injected foam polyethylene dielectric and a precision-drawn, solid copper conductor. These processed materials ensure an exacting 75? impedance, low structural return loss (internal reflections), and minimal attenuation. As a result, the occurrence of cable-induced pulse rounding and jitter is greatly reduced. For comprehensive broadband shielding, a dual shield, foil and braid is used to protect against both high-frequency RF and EMI noise and interference. Cable ends are terminated with Kings 2065 series high-bandwidth BNC video connectors and a flexrelief boot.
