OK, couple of things:

Make sure the radio is grounded well, don't rely on just the negative power lead for the radio grounding. Install a short ground wire from the radio body to the vehicle chassis. This can sometimes fix funny issues like this. Either way, it won't hurt.

As for the antenna,
It could be picking up noise from the computer or other components under the hood. You could try moving it to the opposite side of the hood and see if that helps.
The headache rack can work well. It gets the antenna away from a lot of the noise sources. The ground plane isn't ideal, if you are using an antenna that needs a ground plane, but it'll usually work. For what it's worth, mounting on the fender doesn't provide an ideal ground plane, either.
