    ON EDIT: One thing I noticed right away is that it's much quieter than using my G5RV on 40m. I've always had a high noise floor on 40; I assumed that it was just a fact of life, living in southern CA and all. Turns out maybe its not. I wonder if the vertical matching section on the 'RV has something to do with it.
    Most likely the case, as the vertical matching section is part of the antenna, and closer to man-made noise sources (ie, closer to the ground).

    That's what I was thinking too—the matching section functions as a vertical antenna element and verticals are known to be noisier than horizontally polarized antennas.
    All the world’s a stage, but obviously the play is unrehearsed and everybody is ad-libbing his lines. Maybe that’s why it’s hard to tell if we’re living in a tragedy or a farce.
