True. That's why I mentioned it and its center hole.

He said and outlet plate screw.

Yes, which is at ground potential, but electronics is complicated and
maybe even the array of ground conductors in the average house somehow
makes a decent antenna**.


When dealing with RF there is not much of a real ground on a wire more than
a few feet long. Depending on the frequency for the length of wire, but
where the TV stations operate it only takes a few inches of wire to put you
above ground, so to speak. It will be a ground at direct current and low
frequencies such as 60 HZ.
