FIG. 1 shows the relative gain (loss) of an antenna (e.g., dipole or beam), under varying ground conditions, through the frequency range of 5-30MHz: A represents the curve under perfect ground conditions, B under average ground conditions (i.e., wet grassland), and C under poor ground conditions (dry desert). Note that the influence of ground conditions…

Earth Ground 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…
