Ultra-Lightweight Miniature HDTV/SDI Coax

The Gepco® Brand Ultra-Lightweight Miniature Coax is ideal for mobile production trucks where weight and performance are critical. Maintaining exceptionally low attenuation, the VDM230LT design features a low-loss gas-injected dielectric created with Gepco’s new TactiCel™ Strong Cell Technology, providing improved crush resistance. For reduced weight, the VDM230LT utilizes a copper center conductor and a 100 percent bonded foil with a high-strength, ultra-lightweight liquid crystal polymer braid shielding. Maintaining the same dimensions as Gepco’s VDM230, VDM230LT is compatible with the same connectors and crimp tools previously used for VDM230. This Gepco Ultra-Lightweight Miniature Coax solution is ideal for highdefinition digital video, AWS3id digital audio and standarddefinition digital video interconnect within mobile production trucks.
