Section 1: Includes antenna systems by vehicle.

Perceived reception issues may be a result of environmental factors.

Reception may be diminished in certain areas due to power wires, buildings and/or overpasses.

Aftermarket window tint may interfere with reception.

In cases that are questionable, locate identical vehicle and verify concern (if the like vehicle is the same, condition may be normal).
