What would be the effect of connecting the HF rig and ATU's earth posts to outside earth system, say old cooper pipes for mains water system? I have an outside tap on the wall in the back garden, and checked the conductivity of that tap, with the water pipes running under the kitchen sink, and they are all connected.

What difference does it make, when they are not connected at all? I suppose there would be two different situations where one is for balanced antenna system when earth connection is not needed, and the other case where the antenna is unbalanced and needing earth system.

Is it Must or Optional? Is it good or bad or no difference for the radio system?
