To: <topband@contesting.com> Hi Earl and others, The real key is in the coupling between the systems. If the conductors (antennas) have a high level of mutual coupling, they will affect each other in

Hi Carl, With four carefully pruned resonant radials elevated six feet (measured on 80 meters), the field strength was about 4 or so dB down from 64 radials, either elevated or on the ground. That wa

Carl, The data I posted is mostly from the reports you quoted. IMHO, it is a good idea to have available, read, and attempt to understand what one uses as "evidence" BEFORE using it..not after. If yo

To: <topband@contesting.com> Hi Denny, As Eric pointed out, and I keep pointing out, changing the radials does NOT affect wave angle. It's part of Hamlore and common but incorrect rumor that they do.
