Low-loss triax terminated with precision 75 Ohm impedance. ADC Pro-AxT connectors As with the HD coax series, the foam dielectric in Gepco triax is extruded though a proprietary blending and gasinjection process that achieves a precision 75 Ohm impedance, low attenuation and return loss, superior aging characteristics, and a high level of crush resistance. Unique to triax are two electrically isolated braids to meet the requirements of camera to CCU interconnect. For the overall cable jacket, a flexible, low brittle temperature, abrasionresistant TPE compound is used. These mechanical properties allow for the triax to be used in remote, hostile, and cold weather environments in addition to conventional indoor and studio applications.
