Cecil,

When you short ANY transmission line center to ground and the shield is
grounded, which is what you asked, ALL signal levels will decrease.
They will all go to zero if it is a pefect short.

You have a very strange way of defining noise decreases! If I unplug
the receiver or place it on standby, noise will decrease also. So will
turning off the RF amplifier. So will adding an attenuator.

If shorting the center to shield making noise go away and ignoring the
fact it also makes the signal go away makes you feel like you have
proven something, then I can't go further. That's about the silliest
thing I've ever heard as a logical arguement!
