Passenger rattle at high speeds

[nashasticker]

Hi, I'm new to the forum but have used it for information on my cars. Speaking of which, I've had it with a rattle coming from the passenger side of my 1998 silverado. It only occurs at high speeds 55mph +. It doesn't make a difference if the blower is running, only at higher speeds. It is more than likely a wind vibration and someone once told me that this was due to the air following the antennae wire into the cab. Has anyone had this problem, and if so, how do I fix it? I'm fed up with the NOISE!!!!!
