What is the antenna current path or route

Despite Art`s disdain for amateurs, I`ve found solid information in the "ARRL Antenna Book". Mine contains Characteristics of a lambda/4 monopole which includes: "The current in a lambda/4 monopole varies practically sinusoidally (as is the case with a lambda/2 wire), and is highest at the ground-plane connection. The RF voltage, however is highest at the open (top) end and minimum at the ground-plane connection." The reason for this is already given in this thread. Best regards, Richard Harrison, KB5WZI You still haven't explained your comment regarding the high impedance at the top of an antenna. Are you going to withdraw it? My disdain is for those who put on the mantle of an expert and talk like all is known about antennas without applying any logic of their own |
