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
