Dear Knuckleheads: I am concerned about the lighthearted advice you dispensed during your 5 November 2011 broadcast to the caller from Keller, Texas, whose problem was her car stalling when driving near a 'weather ball' (i.e., an FAA radar dome) on a local road. In order to shield its computer from electromagnetic (EM) radiation which you suspected as the cause, you humourously suggested that she wrap parts of her car in tinfoil. As anyone who has ever mistakenly placed a tinfoil-covered dish in a microwave oven (i.e., a 'radar' range) can attest, the presence of a conductor within an EM field of sufficient strength quickly generates some pretty impressive lightning-like sparks. I shudder to think what might happen to this poor woman (and her tank full of, y'know, gasoline ...) in these potentially disastrous circumstances. It's a good thing that weather dome is located next to a fire station. Seriously -- while it's entirely possible that, by design or defect, her car's electronics are insufficiently shielded from EM, it's also likely that the dome's emitters aren't properly calibrated, and they are putting out a much hotter signal than is necessary. After all, the FAA operators aren't going to worry about a signal with too MUCH reach; they want all the range they can get, to gather them most weather data possible. But if it poses a potential threat to passing motorists (not to mention any birds flying in the vicinity) it's a problem that needs to be addressed. I suggest that you contact your caller and advise her to forget the tinfoil science experiment, and choose a different route, at least. And if that dome thing actually IS a CIA / NSA / Who Knows What Agency listening station, don't worry, they've already heard from you (and me). Best Wishes and Happy Motoring!
