Here's another picture of the blue car. And like the others (except for the black car), it's too far rearward. At least in comparison with the AIM. And according to the AIM, "The antenna should lean inboard approx. 4 degrees (Ref.) when viewed from front of car & stand vertically when viewed from side of car".
Darrell, do you have another picture showing where the antenna is mounted on your car in reference to the mounting location in the AIM?
