    I bought one of these that was made by an amateur club in Fairfield CA back in 1988. It works like gangbusters. I suggest adding a five-foot RG-58 coax line choke wound on a 3-4 inch form.

    My first impression was that since it was wound with insulated #12 house wire that it was actually a capacitive type coupling.

    Regardless, I enjoyed your great explanation.

    Many thanks David. I like to ‘play’ with antennas.
