Humming & Antenna
 

I hear humming after my car has run for about 5 miles. It seems to be louder from inside the car. The other problem is my antenna won't go all the way down. Other than that, I love the car and I've only had it for about 30 days. I had it tuned up, changed the oil oil, had brakes & rotters changed (sorry if I spelled rotters wrong).

HELP the noise is sending me to the nut farm
