[Elecraft] 12 volt battery

[Dale Putnam]

Ground is not necessarily dirt. Ground is what ever medium allows current flow in the return circuit, be it rf.. ac.. dc.. or spikes. However.. each type of current flow.. REQUIRES not only a ground.. but a different ground as in different capabilities, skin or surface flow, multipoint flow,very high current flow are some examples.   A single ground, will not generally provide all that is needed. Yet,  generally, many grounds eventually wind up in dirt. 
Have a great day,
