Do you have your roof rack bars still on top? That whistle is commonly heard from the roof rack cross bars, loosen the tabs and slide both to the rear and the noise will shift farther back and shouldn't bother you. Or pop off the front caps and remove them until you need them for something. My XM/ on star antenna doesn't make a peep, thus why they look like a fish fin to cut through the air.
