Wow. That makes me curious. What was this device, and what is it for? Can you buy it at wal mart?
I bet this guy had no idea that this was gonna get him in this deep!

GPS jammers are illegal in the U.S., and with some high-profile cases in recent years the cheap ones are harder to find now. As I recall, they used to be available for under $50 on eBay a few years back. If you want to spend $120, you can get one from Jammer-Store in Sweden. I did find a cheap one on eBay, though it claims to have a very limited range. I'm dubious as to that claim, so maybe that's just the seller's way of trying to get around U.S. law.
He should have covered the receiving antenna with aluminum foil. Probably effective, if it would stay on, and very cheap.
It would probably take the effort and cost of a pretty good tight metal enclosure to keep the signal weak enough to only affect receivers for a few yards. Just generating the signal right on frequency in a cheap box could spray out many times the power needed for his purpose.
If you ever played around with two AM radios in the same house, you might have noticed that one could be tuned 455 kHz off of a distant station that the other one was receiving and generate a bad whistle. That was because the local oscillator used in the second receiver would spray around unintentionally and cause the interference. They didn't intentionally transmit that interfering signal, but it was pretty strong.
