Currently driving a '05 international 9200 with a Wilson 2000 in the factory mirror mount with new coax run to radio. I will be moving into a '14 peterbilt 579. I can't find an antenna bracket on it anywhere. None above doors, back of sleeper or built into the mirror arms. Popped the trim off inside and no external speaker and I couldn't find any factory wiring for a cb up there either. It's a mid roof without cab extensions and single exhaust behind sleeper. A chain rack will be installed because it will pull flatbed primarily hauling steel plate. What are my options for antenna mounts?
