Radio antenna

Nope, sorry. I know some on stereo and antennas, but you're on your own for Barracuda specific info.
Well, this isn't necessarily Barracuda specific information I'm requesting. I'm just wondering why (according to the factory) that a fiberglass hood would cause a radio to not function properly. If they felt the need to move the antenna to the rear, it must have been causing a reception issue.
