FM Antenna radio static

[Jim8541]

Hello, After installing new fluorescent lights in my basement and garage I can't get FM radio reception. I bought lights from an electrical supply house hoping I would get a better quality ballast that was shielded. I guess not. Any ideas on how I could construct an exterior antenna and attach it to my radio. I read somewhere about wrapping the ballast in aluminum foil but I think heat would be a problem. Any ideas would be helpful.
Thanks, Jim
