Antenna Cable Routing

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Use high quality, 95 percent shield coverage, coaxial, coax, cable. Route the coax away from any electronic components.
Route antenna cables as far away from vehicle wiring as possible in order to reduce the likelihood of the vehicle wiring acting as an antenna for interference.
