There are several tutorials on my website that should help you
understand the issues.

Start with a careful study the "Power and Grounding" tutorial as
background. I am planning to write an expanded version of this for
ham radio.
Also look at the material on "the pin 1 problem" and the material on
ferrites (for background on how RFI happens), including the Power
Point pdf's.
I operated for several years from a second floor shack (that was
also my office) and simple wire antennas in my home in Chicago, with
no problems related to "grounding." See
