Approach Fast Stack cables are fitted (at both ends) with specific connectors to make connections to the Fast Stack Hub and to your avionics. Each Approach cable is typically 24 inches long. The Approach cable for an indicator is typically 36 inches long. The standard power and ground leads are 48 inches. The size of the Fast Stack Pro-G Hub and associated cables permits installation virtually anywhere behind your panel. In addition, since the cables are shorter, there is less noise, less potential for “ground loops” and less voltage losses. All cable wires are Milspec Tefzel and are of proper gauge and shielding. : Approach Fast Stack Systems
