The human body acts a bit like a ground, which the above examples tell us will increase the signal.
I take it you mean connecting one lead to a ground and the other lead to the hot conductor inside a coaxial cable. I don't see why that would work better and it's been my experience that it doesn't. As they say, YMMV.
When connecting to the shield i have found that the signal is scattered. So if you have 7 RG-6 running in a bundle (for example) from the head end out to nearby rooms where they then separate and go their own way...sometimes the toner "rings" on multiple cables. When you use the center conductor its easier to pinpoint the correct cable.
