RocketFish 4' HDMI Cable (RF-G1111) 95% copper braid and dual layer 100% aluminum Mylar foil shields protect against external signal interference. 24K Gold plating offers better corrosion resistance and enhanced signal transfer. Multi stranded, high purity copper conductors improve signal integrity and minimize resistance. Silver soldering maximizes conductivity for better signal transferal. Ergonomic, non slip grip and smooth fit insertion force minimizes risk of damage to connectors or devices.
