I've been having problems with the cable TV recently (Shaw here in Vancouver), and have had the technicians here twice in the last week.

The problem is this: occasionally, and seemingly not when the cable guy is here, channel 6 gets this weird double image. I have a VCR capture, but will not subject you to the torture that it is. Unwatchable. There is also noise on channels 3-5 and 15+16. Anyway, cable guy comes to the house the second time, and after a while we realize that channel 6 is coming in even though the cable is not attached to the wall, and if we disconnect the cable from the TV, no signal at all. The channel was literally strong enough to watch with a small length of wire. Cable guy says the double image is timing between the cable signal and the OTA signal. Oh boy.

So how do I stop that signal from reaching the TV (and cable)? That's right, Faraday Cage! A little bit extreme, I think, but I think a hack solution might work. Chicken wire a la Enemy Of The State?
