Don't like cellphones on freeways? Build a simple jammer and nuke 'em with
about 30 focussed watts of power so they lose lock, drop signal, and hang
up. Wait until they redial and blast 'em again.

I have heard of these devices, and would like to get one. Can you elaborate
on where to buy a ready made unit, or how to build one?
