This is a subject talked about countless times here on wwdx. I couldn't figure out which thread to stick it to so thought I'd post this example here. Pretty wicked stuff. I once disconnected the coax coming from the antenna into the shack and got a little static shock. Not sure if it was from me or from when touching the shield and conductor on the pl259.
This video is on a whole other level though.
