Most of us overlook the importance of hooking good earth grounds to our antennas and our radios. Some think if lightning hits, its going to do what it wants to do. Probably right! Lightning protection is not why I am stressing the earth ground. Good earth grounds serve two purposes. One they protect against lightning (by routing current to the ground instead of our radios). Secondly, they discharge stray RF energy. There are a few things this does for us. First, it makes our receiver quieter (less static). Secondly it prevents RF from building up on the station equipment and distorting our audio (So many CBers have this problem!). Have you every heard someone who’s audio would distort when they would talk? The number one cause of this is strong RF currents running on the radio chassis and mic (more power and the problem gets worse!). Also grounding stray RF energy cuts down on interference to TVs, Phones etc. Plus, if you are using a vertical antenna (1/2,5/8 Wave) you can improve the performance by lowering the angle of radiation by using ground rods and radials running on the surface of the earth under your antenna. This is a total must if you are co-phasing verticals.
