Not at all. I've seen clearly with my own eyes the image of one persons VT100 CRT tube appearing on another across the room because the ground shielding had disconnected. If you have a high gain YAGI antenna, digital RF buffers and some fancy modern DSP lord only knows what you can snoop through the walls.

Most of this is solved by having a simple metal (steel) PC case and grounding the PSU though. Use good quality cables with FCC/IEC badges not the bargain bucket Chinese ones.

I used to see this happen with our old TV's at an old house with really bad grounding. I always wondered why it did that.

We could be playing a video game or movie, and set all the other tv's to channel 2 or something like that, while we played on channel 1. You could see the action on each of them. Almost 1:1 on the reaction times, albeit a little fuzzy.

"Yagi" isn't an acronym.

I learned something today.

  "The antenna was invented in 1926 by Shintaro Uda of Tohoku Imperial
  University, Japan, with a lesser role played by his colleague
  Hidetsugu Yagi." [1]
