It’s often easier to use the theory as a guide to what to try, and then experiment. Experimentation is thus required even if one has done elaborate calculations. There are also exceptional circumstances where grounding increases noise problems, but these, in my experience, are much rarer than the pundits who preach against “ground loops” seem to think.Įven a semi-quantitative theoretical treatment of grounding in oversimplified situations requires heavy math at RF. As you add more, however, you usually reach a diminishing returns (no pun intended) situation where there is no *observable* improvement: that’s usually a good place to stop. With grounds the most common experience is “the more the merrier”.
Is there an advantage in grounding at more than these sites? In article (Larry Picard) writes: In your recent post you advised that coax should be grounded at two sites, first at the antenna and then just before entering the house.
