HIGH DEFINITION TRIAXIAL CABLE

The 75-ohm triaxial cable GF7-TX303D is a form, fit, and function drop-in replacement for the commonly used PIC triaxial cable L7626TX. Meaning the electrical performance, size/weight, connector usage and the applications are the same. This cable is typically used in cabin entertainment video applications, where low levels of EMI cannot be tolerated. In most applications, the internal coax is terminated to the same aerospace connectors as GF7-303D and outer triaxial shield tied to a specified ground point.

This cable is currently available in two jacket colors, standard Laser Markable White and Flight Test Orange.
